     BACKGROUND 
     Background and Relevant Art 
     Bonding of mobile cellular network links refers to the process of combining the bandwidth of multiple individual links (individual modems) to produce a single high-bandwidth link. For example, multiple 3G or 4G links can be bonded together to provide solutions for transferring data with increased bandwidth requirements, such as, video. Typical bonding solutions are designed to broadcast a single video stream or general data.

     DETAILED DESCRIPTION 
     The present invention extends to methods, systems, devices, apparatus, and computer program products for prioritized transmission of different data types over bonded communication modules. In some embodiments, different types of data, including radio communication data to and from aircraft control centers, are communicated between a remotely operated aerial vehicle (e.g., an unmanned aerial vehicle (UAV)) and a control station (e.g., where a pilot remotely controls the UAV) over a bonded communication link. The bonded communication link bonds together the capabilities (e.g., channels) of a plurality of communication devices at the remotely operated aerial vehicle. Radio communication data can represent the content of radio communication transmissions (e.g., the content of VHF airband radio transmissions) that was or is to be transferred over a radio network. 
     Data associated with one or more components (e.g., flight components, monitoring components, cameras, a radio transceiver, etc.) co-located at a remotely operated aerial vehicle is accessed. A plurality of different data types (e.g., flight commands, telemetry, video data, etc.) included in the accessed data are identified. The plurality of different data types includes radio communication data. Reference is made to a data type prioritization scheme to assign a priority to each of the plurality of different data types, including the radio communication data. Link quality is monitored for each of a plurality of communication devices. 
     A subset of communication devices, from among the plurality of communication devices, is selected for transferring the accessed data based on the monitored link qualities and assigned priorities. The subset of communication devices is selected by balancing operating costs for one or more of the plurality of communication devices against having sufficient capability to reliably transfer the accessed data. The accessed data is routed through the bonded communication link in accordance with a data distribution scheme. The accessed data is routed based on the determined priority for each of the plurality of different data types, including the radio communication data, and the monitored link quality for each of the plurality of communication devices. 
     In one aspect, accessed data of one assigned priority is routed over a first communication device included in the subset of communication devices. Accessed data of another assigned priority is routed over a second communication device included in the subset of communication devices. Components at the remotely operated aerial vehicle can refrain from routing accessed data over any non-selected communication devices. 
     The remotely operated aerial vehicle can be user-configurable, allowing different data types to be assigned different priorities. As such, the remotely operated aerial vehicle is able to selectively transmit higher priority data such that lower priority data is sacrificed first in the event of degraded quality at one or more communication devices (e.g., modems, network interface cards, etc.). Quality degradation may be in terms of reduced signal strength, reduced bandwidth or increased latency of the bonded link as a whole, or of one or more of the individual communication devices that are bonded. 
     Communication between the remotely operated aerial vehicle and a control device can be via a cellular or other wireless network. The control device includes a (e.g., Internet Protocol (IP)) network port providing a connection to the cellular or other wireless network. The port is able to re-assemble data streams (e.g., IP packets) received from the portable device and generate output data streams corresponding to the portable device input data sources. Both the remotely operated aerial vehicle and the control device include the ability to detect missing data packets and request packet resends. 
     In some aspects, different types of data are communicated between a remotely operated aerial vehicle (e.g., an unmanned aerial vehicle (UAV)) and a control station (e.g., where a pilot remotely controls the UAV) over bonded communication channels of one or more communication devices. In one aspect, data transmission is essentially simultaneous with each data type assigned a different priority. 
     For example, video from cameras mounted to a UAV and telemetry data indicating the status of vehicle flight systems at the UAV can be essentially simultaneously transmitted from the UAV to a control station. Command data for controlling the UAV can also be essentially simultaneously received at the remotely operated aerial vehicle from the control station. Radio communication data representing the content of radio transmissions received from an aircraft control center can be sent to the control station. Radio communication data representing the content of radio transmissions to be transmitted (and intended for an aircraft control center) can be received from the control station. The video, telemetry data, command data, and radio communication data can be transferred over bonded communication channels (e.g., from among 3G cellular, 4G cellular, satellite, Wi-Fi, WiMAX, etc.) at the remotely operated aerial vehicle. 
     Thus, aspects of the invention can be used to facilitate (e.g., more localized) radio communication between an operator (e.g., pilot) of a Remotely Operated Aerial Vehicle and a controlling entity when the operator (e.g., pilot) is physically located outside of (e.g., VHF) radio range from the controlling entity. In some aspects, a Remotely Operated Aerial Vehicle is a Remotely Piloted Aircraft (RPA) (and is potentially unnamed, for example, an Unmanned Aerial Vehicle (UAV)). In some aspects, a remotely operated aerial vehicle is a rotor-based UAV that includes a plurality of rotors. In some aspects, a rotor-based UAV is a quad-rotor UAV. In other aspects, a rotor-based UAV includes five or more rotors. A rotor based UAV can use rotors for one or more of: lift, maneuvering, and to change orientation, including vertical takeoff and landing (“VTOL”). 
     In this description and the following claims, “Airband” or “Aircraft band” is defined as a group of frequencies in the VHF radio spectrum allocated to radio communication in civil aviation, sometimes also referred to as VHF, or phonetically as “Victor”. Different sections of the band are used for radio navigational aids and air traffic control. The VHF airband can use frequencies between 108 and 137 MHz. The lowest 10 MHz of the band, from 108-117.95 MHz, can be split into 200 narrow-band channels of 50 kHz. These can be used for navigational aids such as VHF Omni Directional Radio Range (“VOR”) beacons, and precision approach systems such as Instrument Landing System (“ILS”) localizers. 
     Aircraft communications radio operations can use amplitude modulation (AM), such as, for example, A3E double sideband with full carrier on VHF and UHF, and J3E single sideband (SSB) with suppressed carrier on HF. AM and SSB permit stronger stations to override weaker or interfering stations. Alternative analog modulation schemes, such as the “CLIMAX” multi-carrier system and offset carrier techniques can also be used. Aspects of the invention can also be used when airband communication is facilitates with digital radios. 
     A reliable, low-latency, high-bandwidth communications link may be useful for transmitting a variety of different types of data. For example, an unmanned aerial vehicle (UAV) may be fitted with surveillance cameras (in addition to flight components, wireless communication components, a radio system etc.). The UAV can use a reliable, low-latency, high-bandwidth communications link for sending radio communication data (e.g., corresponding to received VHF airband communication), video and telemetry data to a ground-based operator and for receiving radio communication data (e.g., to be transmitted as VHF airband communication) and commands from the ground-based operator. Telemetry data is used to monitor the state of the aircraft and commands are used to control vehicle operation. Radio communication data can include tower and/or control center instructions and responses. 
     As such, radio communication data (e.g., corresponding to VHF airband communication), telemetry data and command data can have increased mission importance relative to video. Failure to transmit telemetry data, and/or receive command data could cause control of a remotely operated aerial vehicle to be lost. For example, for a UAV, losing ground-to-aircraft command data could result in total loss of the UAV. Failure to transmit or receive tower radio communications has safety implications for the remotely operated aerial vehicle as well as other aircraft 
     Some techniques rely on separate, un-bonded links for transmitting video and telemetry data from an aircraft to the ground, and command data from the ground to the aircraft. Thus, if a channel for telemetry and/or commands is malfunctioning and another channel for video is operational and/or has available bandwidth, there may be no way to make use of (or “take over”) the other channel for telemetry data and/or commands. If the malfunction is significant, an aircraft could potentially be lost even though a functioning communication channel exists. 
     On the other hand, interruption of a video stream would not adversely affect the integrity and/or safety of the UAV (or other aircraft). Thus, radio communication data, telemetry data, and command data can be given higher priority relative to video. In the event of a malfunction or degraded quality of a link, video and other lower priority data can be sacrificed to increase the chances of radio communication data, telemetry data, and/or command data being appropriately transferred. 
     As described, a remotely operated aircraft can be operated by an operator (e.g., a certified pilot) from a control station. In one aspect, the operator can use the control station to fly the remotely operated aircraft past line of sight. The remotely operated aircraft can be certified for past line of sight flight by appropriate government and/or regulatory authorities, such as, for example, the Federal Aviation Administration (FAA), Transport Canada Civil Aviation (TCCA), European Aviation Safety Agency (EASA), Civil Aviation Administration of China (CAAC), etc. for the country in which it is operating. 
     A remotely operated aerial vehicle can include wireless communication components (e.g., one or more modems) for wireless communication with a control station via one or more wireless networks. The one or more wireless networks can span various communication channels (e.g., bonded and/or redundant cellular channels, satellite channels, WiMax channels, etc.) between the remotely operated aerial vehicle and the control station. In general, the control station uses the wireless communication channels to exchange data with the remotely operated aerial vehicle and vice versa. For example, the control station can use the wireless communication channels to communicate (data and/or voice) with the remotely operated aerial vehicle, to send operator commands to the remotely operated aerial vehicle, to receive vehicle status from remotely operated aerial vehicle, etc. 
     The remotely operated aerial vehicle can also include radio communication components (e.g., transceiver and antenna) for radio communication via a radio network. For example, the remotely operated aerial vehicle can include a radio system for radio communication with controlling entities (e.g., aircraft control centers). The radio system can include a transmitter, a receiver, and an antenna. In one aspect, the radio system facilitates Very High Frequency (VHF) radio communication (e.g., between 30 MHz to 300 MHz and more particularly VHF airband communication in frequencies between 108 MHz and 137 MHz) and/or Ultra High Frequency (UHF) radio communication (e.g., between 300 MHz and 3 GHz). However, other communication mechanisms are also contemplated. The receiver can receive radio communication (e.g., VHF and/or UHF communication) from a controlling entity (e.g., a control center) or other aircraft. The transmitter can transmit radio communication (e.g., VHF and/or UHF communication) to a controlling entity (e.g., a control center) or other aircraft. The antenna can convert electric power into radio waves, and vice versa. 
     To transmit, the transmitter supplies an electric current oscillating at radio frequency (e.g., a high frequency alternating current (AC)) to the antenna&#39;s terminals. The antenna radiates the energy from the current as electromagnetic waves (i.e., radio waves) at the radio frequency. To receive, the antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals, that is applied to a receiver to be amplified. 
     The remotely operated aerial vehicle further includes a communication converter. The communication converter can convert between wireless communication formats compatible for transmission via the one or more wireless networks and radio communication formats compatible for transmission via the radio network and vice versa. For example, the communication converter can convert communication from cellular (or satellite) to VHF radio (e.g., VHF airband communication in frequencies between 108 and 137 MHz.) and/or UHF radio and vice versa. Accordingly, an operator (or pilot) flying a remotely operated aircraft from a control station can communicate with a controlling entity (e.g., a control center) using VHF radio and/or UHF radio communication as if the operator (or pilot) was essentially in the same physically location as the remotely operated aircraft. That is, VHF radio and/or UHF radio transmissions can originate from the remotely operated aircraft and VHF radio and/or UHF radio waves can be received at the remotely operated aircraft. 
       FIG. 1  illustrates an example architecture  100  that facilitates prioritized transmission of different data types over bonded communication modules. As depicted, architecture  100  includes a view of Unmanned Aerial Vehicle (UAV)  101 , control device  121 , and network  131  (e.g., a cellular network). In one aspect, UAV  101  is certified for past line of sight flight by appropriate government and/or regulatory authorities, such as, for example, the Federal Aviation Administration (FAA), Transport Canada Civil Aviation (TCCA), European Aviation Safety Agency (EASA), Civil Aviation Administration of China (CAAC), etc. for the country in which it is operating. UAV  101  can be powered on and a certified pilot (e.g., through control device  121 ) can be maneuvering UAV  101  on the ground or in the air. 
     UAV  101  includes packet distributor  102 , packet inspector and re-assembler  103 , network link monitor  104 , packet inspector and prioritize  105 , video stream packet generator  106 , data stream packet generator  107 , video encoder  108 , analog to digital converter  109 , modems  111 ,  112 ,  113 ,  114 , and  115 , antenna  183 , transceiver  184 , converter  186 , and one or more other antennas (not shown). The individual bandwidth provided by channels at each of modems  111 ,  112 ,  113 ,  114 , and  115  can be bonded into bonded communication link  142 . 
     Packet distributor  102  is configured to inspect headers of incoming data (e.g., Internet Protocol (IP) packets) to establish their priority. Based on priority and a packet distribution scheme, packet distributor  102  routes packets to individual modems from among modems  111 ,  112 ,  113 ,  114 , and  115  taking into account modem link qualities. 
     Packet inspector and re-assembler  103  is configured to receive data (e.g., IP packets) from modems  111 ,  112 ,  113 ,  114 , and  115  and place them in a buffer. Packet inspector and re-assembler  103  can search the buffer for the next packet in the sequence based on the packet sequence numbers. If a packet is still missing after a timeout, a resend request is sent with higher priority. Once the next packet in the sequence has been found it is output via the data output port  120 . 
     For outgoing radio (e.g., VHF airb and) communication, a packets of radio communication data, such as, for example, radio communication data  181 , can be received from control device  121 . In one aspect, radio communicating data is received via a microphone at control device  121  (e.g., an operator of control device  121  can speak into the microphone). The packets of radio communication data  181  can be passed to converter  186  for transmission as radio communication  182 . Converter  186  can convert the packets for radio transmission by transceiver  184 . Transceiver  184  can convert the packet to electrical current. Antenna  183  can in turn transmit the electrical current as radio waves (e.g., including radio communication directed to a control center (e.g., tower)). In one aspect, transmitted radio waves are in the VHF airband radio communication frequencies (but can also be in other VHF frequencies or can be in UHF frequencies). 
     For incoming radio waves at radio  182 , antenna  183  can convert received radio waves to electrical currents. Transceiver  184  can process the electrical currents into radio communication. Converter  186  can convert the radio communication to data packets of radio communication data. Converter  186  can send the data packets to packet inspector and prioritizer  105 . In one aspect, received radio waves are in the VHF airband radio communication frequencies (but can also be in other VHF frequencies or can be in UHF frequencies). 
     Network link monitor  104  is configured to monitor the link quality of each of modems  111 ,  112 ,  113 ,  114 , and  115 . Network link monitor  104  can send monitored link quality information to other modules of UAV  101  and/or to control device  121 . 
     Packet inspector and prioritizer  105  is configured to inspect headers of incoming data (e.g., IP packets) to establish a data type. A data type can be, for example, any of: radio communication data, telemetry data, command data, video data, audio data, etc. Using a data type prioritizing scheme and data type priorities provided via configuration input, packet inspector and prioritizer  105  can insert a priority identifier in each (e.g., IP packet) header. Packet distributed  102  can refer to the priority identifiers when routing data through one or more of modems  111 - 115 . 
     Video stream packet generator  106  takes an encoded video stream and breaks it up into a sequence of (e.g., IP) packets. Video stream packet generator  106  can insert a label in each packet header to identify it as a video stream packet. Video stream packet generator  106  can also insert a packet sequence number in the header to allow re-assembling packets in the correct order once received by the receiver. 
     Data stream packet generator  107  is configured to take an input data stream and break it up into a sequence of (e.g., IP) packets. Data stream packet generator  107  can insert a label in each packet header to identify it as a data packet. In some embodiments, different labels are also used to distinguish between different types of data, such as, for example, operational data, status data, etc. Different types of data can come from different systems, such as, flight systems (e.g., at, integrated with, and/or attached to UAV  101 ). Different types of data can include radio data, power data (e.g., battery status), engine data, environmental data (e.g., temperature, altitude, direction, etc.), etc. 
     Video encoder  108  is configured to encode a digital video stream into a lower bitrate format by employing a compression algorithm (such as H.264). A target bitrate can be specified via configuration input. The degree of compression can be varied based on feedback from the network link monitor  104 , so that the bitrate is adjusted to correspond to available bandwidth of bonded communication link  142 . 
     Analog to digital converter  106  is configured to covert analog video to digital video for processing at video encoder  108 . 
     As described, antenna  183  can convert received radio waves (e.g., from a control tower) to electrical currents. Transceiver  184  can process the electrical currents into radio communication. Converter  186  can convert the radio communication to one or more packets of radio communication data. Converter  186  can send the one or more packets of radio communication data to packet inspector and prioritizer  105 . 
     In some embodiments, UAV  101  also includes one or more separate audio input channels (analog and/or digital). In these embodiments, UAV  101  also includes appropriate components for converting analog audio to digital audio, encoding a digital audio stream, and breaking an audio stream into a sequence of packets. 
     Accordingly, the depicted components of UAV  101  can be connected to and exchange data with other components at UAV  101 . For example, analog to digital converter  109  can receive analog video from analog video input  116 . Analog video can be captured at analog cameras (e.g., at, integrated with, and/or attached to UAV  101 ). Video encoder  108  can receive digital video from digital video input  117 . Digital video can be captured at digital cameras (e.g., at, integrated with, and/or attached to UAV  101 ). Analog to digital converter  109  can convert analog video into digital video. Video encoder  108  can encode digital video and converted analog video into a video stream. 
     Alternately or in combination, analog and/or digital audio can be captured at condensers (e.g., at, integrated with, and/or attached to UAV  101 ). An audio encoder can encode digital audio and convert analog audio into an audio stream. 
     Data stream packet generator  107  can receive data (e.g., telemetry data of different data types) from data input  118 . Data can originate at other (e.g., vehicle, flight, monitoring etc.) systems and/or components (e.g., at, integrated with, and/or attached to UAV  101 ). Data stream packet generator  107  can turn data  118  into a data stream. Packet inspector and prioritizer  105  can receive configuration (e.g., telemetry data of different data types) from device configuration input  119 . Configuration  119  can indicate the configuration of other (e.g., vehicle, flight, monitoring, etc.) systems and/or components (e.g., at, integrated with, and/or attached to UAV  101 ). 
     Packet inspector and re-assembler  103  can receive data (e.g., IP packets) from modems  111 ,  112 ,  113 ,  114 , and  115 . Packet inspector and re-assembler  103  can formulate data (e.g., commands) to output to other components at data output  120 . Data can be output to other (e.g., vehicle, flight, mentoring, etc.) systems and/or components (e.g., at, integrated with, and/or attached to UAV  101 ) to give commands to those other systems. Packet inspector and re-assembler  103  can also formulate radio communication data to send to converter  186 . 
     As depicted, control device  121  includes network port  122  (e.g., a wired connection), inspector and re-assembler  123 , and video decoder  124 . 
     Inspector and re-assembler  123  is configured to receive data (e.g., IP packets) from network  131  through network port  122 . Inspector and re-assembler  123  can sort data into buffers based on data type. A data type can be, for example, one of one or more different types of radio communication data, telemetry data, command data, video, audio, etc. Inspector and re-assembler  123  searches each buffer for the next packet in the sequence of that data type based on the packet sequence numbers. If a packet is still missing after a timeout, a resend request is sent. Once the next packet in the sequence has been found for a packet type, it is output to the appropriate stream. Video data can be output to video decoder  124 , while data packets are output to the data output port  128 . Radio communication data, such as, for example, radio communication data  181 , can be sent to a headset or speakers for rendering to an operator of UAV  101 . 
     Video decoder  124  is configured to decode video data (e.g., packets) into a digital video stream. Video decoder  124  can output a digital video stream at video output  127 . 
     When appropriate, control device  121  can also include an audio decoder to decode audio data (e.g., packets) (which may be radio communication) into a digital audio stream and output the digital audio stream at an audio output port. 
     Data output at data output port  128 , digital video stream data output at video output  127 , and an audio data stream output at an audio output port can be presented at one or more output devices, for example, a display screen and speakers, associated with control device  121 . Control device  121  can also receive configuration and data (e.g., commands for controlling UAV  101  through configuration input port  126  and data input port  129  respectively. Configuration input port  126  and data input port  129  can be connected to one or more input devices (e.g., vehicle control devices, such as, flight control devices) associated with control device  121 . Input devices can include keyboards, mice, flight sticks, etc. manned, for example, by a vehicle operator (e.g., pilot). 
     Thus, generally, UAV  101  can transmit one or more of radio communication, other audio, video, telemetry data, etc. over network  131  to control device  121 . Control device  121  can receive one or more of radio communication, other audio, video, telemetry data, etc. over network  131  from UAV  101 . Similarly, control device  121  can send radio communication data and command data to UAV  101  over network  131 . UAV  101  can receive radio communication data and command data over network  131  from control device  121 . 
     A packet distribution scheme can be used to distribute data (e.g., IP packets). The packet distribution scheme minimizes disruption in transmission of higher priority data types when the signal quality degrades. Any of a variety of different schemes for distributing data (e.g., IP packets) between individual modems (e.g., from among modules  111 ,  112 ,  113 ,  114 , and  115 ) based on their priority can be used. 
     In one aspect, telemetry navigation data is highest priority, Air Traffic Control (ATC) radio communication the second highest priority, other (payload) communication is the third highest priority, and sensor or peripheral data is the fourth highest priority. 
     In general, network link monitor  104  can establish which modem(s) have the best link quality, and packet distributor  102  can route the higher priority packets via these modem(s). For example, at UAV  101  a modem with higher (or even the best) link quality can be used exclusively for telemetry data or exclusively for certain types of telemetry data (or radio communication data). 
     In another embodiment, higher priority packets can be routed via a plurality of (and possible all) modems. Having higher priority, available bandwidth is allocated first to these packets. Packets with lower priority are relegated to being sent when remaining bandwidth permits. 
     Optionally, packet distributor  102  may refrain from distributing data through one or more modems due to cost in accordance with a packet distribution scheme. For example, if sufficient bandwidth is available from cheaper to operate modems (e.g., 1G) then other costlier to operate modems (e.g., satellite) are not used. When appropriate, dictated at least in part by link characteristics, costlier modems can be used to transfer higher priority data. For example, if all the 1G modems in a vehicle are out of range of a cell tower, a satellite modem can be used to transfer tower radio communication, send telemetry, and receive vehicle commands until 1G service is again available. 
     Thus, in general, UAV  101  can control the routing of radio communication data, telemetry data, command data, audio, and video between control device  121  and other systems and/or components of UAV  101  (e.g., at, integrated with, and/or attached to UAV  101 ). UAV  101  can give data types related to radio communication, data types related to monitoring specified (e.g., vehicle, flight, etc.) systems, and/or data types related to controlling specified (e.g., vehicle, flight, etc.) systems higher priority. Some telemetry data may be designated to have higher priority relative to other telemetry data and radio communication data. For example, telemetry data indicating a low engine battery can be given a higher priority than telemetry data indicating temperature. Similarly, some types of commands may be designated have higher priority over other types of commands. For example, a command to electrically isolate a malfunctioning battery can be given a higher priority than a command for panning or tilting a camera. 
       FIG. 2  illustrates a flow chart of an example method  200  for prioritized transmission of different data types over bonded communication modules. Method  200  will be described with respect to the components and data of computer architecture  100 . 
     Method  200  includes accessing data associated with one or more components co-located with a UAV ( 201 ). For example, UAV  101  can access any of analog video  116 , digital video  117 , data  118 , configuration  119 , radio communication  182 , and data  120 . 
     Method  200  includes identifying a plurality of different data types included in the accessed data, the plurality of different data types including radio communication data ( 202 ). For example, packet inspector and prioritizer  105  can identify data types for any of: analog video  116 , digital video  117 , data  118 , configuration  119 , radio communication  182 , and data  120 . Method  200  includes referring to a data type prioritization scheme to assign a priority to each of the plurality of different data types including the radio communication data ( 203 ). For example, packet inspector and prioritizer  305  can refer to a data type prioritization scheme to assign a priority to any of: analog video  116 , digital video  117 , data  118 , configuration  119 , radio communication  182 , and data  120 . 
     Method  200  includes monitoring a link quality for each of a plurality of communication devices ( 204 ). For example, network link monitor  104  can monitor a link quality for each of modems  111 - 115 . Link quality can be monitored on an ongoing basis, such as, for example, at specified intervals, in response to a request from any of modems  111 - 115 , in response to a request from control device  121 , when changes in data type or data volume are detected, when distance to a cell tower changes, when entering a new control area, etc. 
     Method  200  includes selecting a subset of communication devices, from among the plurality of communication devices, for transferring the accessed data based on the monitored link qualities and assigned priorities, the subset of communication devices selected by balancing operating costs for one or more of the plurality of communication devices against having sufficient capability to reliably transfer the accessed data ( 205 ). For example, network link monitor  104  can select modems  111 - 113  (a subset of modems  111 - 115 ) for transferring any of: analog video  116 , digital video  117 , data  118 , configuration  119 , radio communication  182 , and data  120  to control device  121 . The modems  111 - 113  can be selected based on the monitored link qualities for each of modems  111 - 115  and assigned priorities for any of: analog video  116 , digital video  117 , data  118 , configuration  119 , radio communication  182 , and data  120 . 
     The modems  111 - 113  can be selected to balance operating costs for one or more of modems  111 - 115  against having sufficient capability (e.g., bandwidth) to reliably transfer any of: analog video  116 , digital video  117 , data  118 , configuration  119 , radio communication  182 , and data  120 . 
     A selected subset of communication devices can change over time based on changes in monitored link qualities and/or changes to assigned data priorities. 
     Method  200  includes routing the accessed data through the bonded communication link in accordance with a data distribution scheme based on the determined priority for each of the plurality of different data types, including the radio communication data, and the monitored link quality for each of the plurality of communication devices ( 206 ). For example, packet distributor  102  can route any of: analog video  116 , digital video  117 , data  118 , configuration  119 , radio communication  182 , and data  120  to control device  121  in accordance with a data distribution scheme. The routing can be based on the assigned priority for each of: analog video  116 , digital video  117 , data  118 , configuration  119 , radio communication  182 , and data  120  and the monitored link quality for each of modems  111 - 115 . 
     Routing the accessed data can include routing accessed data of one assigned priority over a first communication device included in the subset of communication devices. For example, packet distributor  102  can route radio communication  182  over modem  111 . Routing the accessed data can include routing accessed data of another assigned priority over a second communication device included in the subset of communication devices. For example, packet distributor  102  can route configuration  119  over modem  112 . Routing the accessed data can include refraining from routing accessed data over any non-selected communication devices. For example, packet distributor  102  can refrain from routing any data over modems  114  and  115 . 
     As described, monitored link qualities and assigned priorities can be used to both facilitate selection a subset of communication devices and facilitate routing accessed data in accordance with a data distribution scheme. 
     In one aspect, data of higher priority is routed over communication devices having higher link quality and data of lower priority is routed over communication devices having lower link quality. 
     In some aspects, audio and video have a lower priority than other types of data (video can have a lower priority than audio or vice versa). The other data types can be designated to have higher or lower priority relative to one another. Data type designations can be made by a vehicle owner, a vehicle operator (e.g., pilot), set by (e.g., Federal Aviation Administration (FAA)) standards or regulations, etc. For UAVs, higher priority can be given to (e.g., telemetry, command, and radio communication) data related to the air worthiness and safety of the UAV. 
     Control device  121  can be software running on a personal computer. An operator (e.g., a pilot) can use control device  121  to operate UAV  101  past line of sight and possibly a significant distance away, for example, from another state or country 
     In some aspects, data is prioritized based on an associated input or output port. Thus, UAV  101  could prioritize based on data stream. For example, UAV  101  could prioritize zero or more digital inputs and/or zero or more analog inputs. 
     Control device  121  can be at a fixed location or can be mobile. For example, control device  121  can be in a mobile command center (e.g., a land based vehicle). When control device  121  is mobile, control device  121  can also include a plurality of modems bonded into a bonded link (e.g., replacing port  122 ). In some embodiments, depending on available communication modules, UAV  101  is at, integrated with, and/or attached to other components and control device  121  is at, integrated with, and/or attached to another aircraft. The other aircraft can be another UAV. As such, one UAV can serve as a relay between another UAV and a ground station or other control center. 
     Modems in a bonded link (either in UAV  101  or control device  121 ) can be of the same or different brands, types, capabilities, etc. For example, a bonded link can include any and different combinations of 3G cellular, 4G cellular, satellite, Wi-Fi, WiMAX, etc., modems or interface cards. In some aspects, operating costs are balanced against having sufficient capabilities to reliable transfer accessed data. A bonded link can include a number of cheaper to operate modems (e.g., 3G) along with other more costly to operate modems (e.g., satellite). The more costly to operate modems can be used when the cheaper to operate modems fail to provide sufficient bandwidth for reliable transfer of accessed data and thus for safely operating a vehicle. 
     Aspects of the invention can be used to prioritize the routing of radio (e.g., VHF airband) communication, video, audio, and data to and from vehicles. The vehicles can be a land based, aerial (fixed wing and/or rotary), marine based (submersible or non-submersible), or space based vehicles. Vehicles can have a vehicle operator (either in the vehicle or operating the vehicle remotely). In one aspect, a vehicle is a Remotely Piloted Aircraft (RPA). 
     UAVs and control devices can include computer network connectivity components (e.g., a Network Interface Card (“NIC”) or cellular modem) for wired or wirelessly connecting the cameras, condensers and other components to a computer network. As such, modules, algorithms, components, etc., for routing prioritized data, audio and video through a bonded link can also be connected to other modules, algorithms, components, etc., over (or be part of) a network, such as, for example, a Local Area Network (“LAN”), a Wide Area Network (“WAN”), and even the Internet. Accordingly, the modules, algorithms, components, etc., for routing prioritized data, audio and video through a bonded link as well as any other connected computer systems and their components (e.g., in a control or command center), can create message related data and exchange message related data (e.g., Internet Protocol (“IP”) datagrams and other higher layer protocols that utilize IP datagrams, such as, Transmission Control Protocol (“TCP”), Hypertext Transfer Protocol (“HTTP”), Simple Mail Transfer Protocol (“SMTP”), etc. or using other non-datagram protocols) over the network. 
     As such, modules, algorithms, components, etc., for routing prioritized data, audio and video through a bonded link can be operated (e.g., remotely) over the computer network. When a control system (e.g., control device  121 ) is used to control a vehicle (whether the vehicle is manned or unmanned), the control system can also be used to control routing prioritized data, audio and video at a vehicle through a bonded link. 
     In some aspects, routing prioritized radio (e.g., VHF airband) communication, data, audio, and video through a bonded link is provided though autonomous operation by a robotic vehicle or system. For example, a robotic vehicle or system can route prioritized data, audio and video through a bonded link. 
     Wireless Communication Between an Operator of a Remotely Operated Aircraft and a Controlling Entity 
     Aspects of the invention also extend to methods, systems, devices, apparatus, and computer program products for wireless communication between an operator of a remotely operated aircraft and a controlling entity. A remotely operated aircraft is operated by an operator (e.g., pilot) from a control station. The operator can use the control station to fly the remotely operated aircraft past line of sight. The remotely operated aircraft can be certified for past line of sight flight by appropriate government and/or regulatory authorities, such as, for example, the Federal Aviation Administration (FAA), Transport Canada Civil Aviation (TCCA), European Aviation Safety Agency (EASA), Civil Aviation Administration of China (CAAC), etc. for the country in which it is operating. 
     The remotely operated aircraft includes wireless communication components (e.g., one or more modems) for wireless communication via one or more wireless networks. The one or more wireless networks can span various communication channels (e.g., bonded and/or redundant cellular channels, satellite channels, WiMax channels, etc.) between the remotely operated aerial vehicle and the control station. In general, the control station uses the wireless communication channels to exchange data with the remotely operated aircraft. For example, the control station can use the wireless communication channels (e.g., any of modems  111 - 115  over network  131 ) to communicate (data and/or voice) with the remotely operated aerial vehicle, to send operator commands to the remotely operated aerial vehicle, to receive vehicle status from remotely operated aerial vehicle, etc. 
     The remotely operated aircraft also includes radio communication components (e.g., transceiver and antenna) for radio communication via a radio network. For example, the remotely operated aerial vehicle can include a radio system for radio communication with controlling entities (e.g., control centers). The radio system can include a transmitter, a receiver, and an antenna. In one aspect, the radio system facilitates Very High Frequency (VHF) radio communication (e.g., between 30 MHz to 300 MHz and more particularly VHF airband communication in frequencies between 108 MHz and 137 MHz) and/or Ultra High Frequency (UHF) radio communication (e.g., between 300 MHz and 3 GHz). However, other communication mechanisms are also contemplated. The receiver can receive radio communication (e.g., VHF and/or UHF communication) from a controlling entity (e.g., a control center) or other aircraft. The transmitter can transmit radio communication (e.g., VHF and/or UHF communication) to a controlling entity (e.g., a control center) or other aircraft. The antenna can convert electric power into radio waves, and vice versa. 
     To transmit, the transmitter supplies an electric current oscillating at radio frequency (e.g., a high frequency alternating current (AC)) to the antenna&#39;s terminals. The antenna radiates the energy from the current as electromagnetic waves (i.e., radio waves) at the radio frequency. To receive, the antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals, that is applied to a receiver to be amplified. 
     The remotely operated aircraft further includes a communication converter. The communication converter can convert between wireless communication formats compatible for transmission via the one or more wireless networks and radio communication formats compatible for transmission via the radio network and vice versa. For example, the communication converter can convert communication from cellular (or satellite) to VHF radio (e.g., VHF airband communication in frequencies between 108 and 137 MHz.) amd/or UHF radio and vice versa. Accordingly, an operator (or pilot) flying a remotely operated aircraft from the control station can communicate with a controlling entity (e.g., a control center) using VHF radio and/or UHF radio communication as if the operator (or pilot) was essentially in the same physically location as the remotely operated aircraft. That is, VHF radio and/or UHF radio transmissions can originate from the remotely operated aircraft and VHF radio and/or UHF radio waves can be received at the remotely operated aircraft. 
     In one aspect, the radio components are used to receive radio communication via the radio network (e.g., VHF airband). The radio communication is in a radio format compatible for transmission over the radio network. The radio communication is received from an aircraft control center transmission. The communication converter converts the radio communication from the radio format to another format. The other format is compatible for transmission over another wireless communication network (e.g., cellular channels, satellite channels, WiMax channels, etc.). The wireless communication components are used to send the wireless communication in the other format via the other wireless communication network (e.g., network  131 ). The wireless communication is sent to a control station used to control the remotely operated aircraft. 
     In another aspect, the wireless communication components are used to receive other wireless communication (that may be responsive to the wireless communication) via a (e.g., the other) wireless communication network (e.g., cellular channels, satellite channels, WiMax channels, etc.). The other wireless communication is in a (e.g., the other) format compatible for transmission over the (e.g., other) wireless communication network (e.g., network  131 ). The other wireless communication is received from the control station used to control the remotely operated aircraft. The communication converter converts the other wireless communication from the format to the radio format. The radio components are used to send the other wireless communication in the radio format to the aircraft control center via the radio network (e.g., VHF airband). 
     Accordingly, aspects of the invention can be used to facilitate (e.g., more localized) radio communication between an operator (e.g., pilot) of a remotely operated aircraft and a controlling entity (e.g., a control center) when the operator (e.g., pilot) is physically located outside of (e.g., VHF and/or UHF) radio range from the controlling entity. In some aspects, a remotely operated aircraft is a certified Remotely Piloted Aircraft (RPA) (and is potentially unnamed, for example, an Unmanned Aerial Vehicle (UAV)) being controlled by a certified pilot. 
     Turning to  FIG. 3 ,  FIG. 3  illustrates an example architecture  300  that facilitates radio communication between pilot  311  of Remotely Piloted Aircraft (RPA)  301  and control center  309 . Architecture  300  includes RPA  301 , control center  309 , control station  312 , and pilot  311 . In general, pilot  311  uses control station  312  to communicate with and control (e.g., flight characteristics of) RPA  301 . In one aspect, pilot  311  is a certified pilot operating RPA  301  past line of sight and possibly a significant distance away, for example, from another state or country. RPA  301  can be certified for past line of sight flight by appropriate government and/or regulatory authorities, such as, for example, the Federal Aviation Administration (FAA), Transport Canada Civil Aviation (TCCA), European Aviation Safety Agency (EASA), Civil Aviation Administration of China (CAAC), etc. for the country in which it is operating. 
     Control station  312  can communicate with RPA  301  using wireless technologies including bonded and/or redundant cellular channels, satellite channels, WiMax channels, etc. For example, control station  312  can use cellular communication to communicate with (both send data and commands to and receive data and telemetry from) RPA  301 . Cellular communication can be used to transfer data as well as voice communication between control station  312  and RPA  301 . Pilot  311  can utilize audio input device(s) (e.g., a microphone) and audio output devices (e.g., speakers, headphones, etc.) at control station  312  to exchange voice communication (or other audio data) with RPA  301 . 
     As depicted, RPA  301  includes cellular communication components  302  (e.g., circuitry), communication converter  303 , VHF radio communication components  304  (e.g., transmitter and receiver circuitry), antenna  306 , processor  307 , and memory  308 . Cellular communication components  302  are configured to exchange (send and receive) cellular communication (voice and/or data) with other systems, such as, for example, control station  312 . Communication converter  303  is configured to convert (voice and/or data) between cellular communication and VHF (e.g., VHF airband) radio communication. VHF radio communication components  304  are configured to exchange (send and receive) VHF radio communication (voice and/or data) with other systems, such as, for example, control center  309 . 
     During operation, pilot  311  can maneuver RPA  301  (e.g., on the ground and/or in the air) within control area  319 . In one aspect, pilot  311  flies RPA  301  into control area  319  from elsewhere. Control area  319  can be a geographical area of control, for example, an area around an airport, a flight information region, etc. controlled by control center  309 . Control center  309  can control air traffic around an airport, ground traffic at an airport, etc. Control center  309  can be an Air Route Traffic Control Center (ARTCC), a TRACON (Terminal Radar Approach Control), an oceanic airspace controller (including oil rig mounted components), etc. 
       FIG. 4A  illustrates a flow chart of an example method  400  for transmitting wireless communication from a control center to an operator of a Remotely Operated Aircraft. Method  400  will be described with respect to the components and data of architecture  300 . 
     Method  400  includes using radio communication components at a Remotely Piloted Aircraft (RPA) to receive wireless communication via a radio network, the wireless communication in a radio format compatible for transmission over the radio network, the wireless communication received from an aircraft control center ( 401 ). For example, antenna  306  can receive the VHF radio (e.g., airband) communication  323  and convert the radio waves into electric current. The electric current can be processed at a receiver included in VHF radio communication components  304 . The receiver and antenna  306  can interoperate to access voice communication  331  in radio format  331 R. 
     Method  400  includes using a communication converter at the Remotely Piloted Aircraft (RPA) to convert the wireless communication from the radio format to another format, the other format compatible for transmission over another wireless communication network ( 402 ). For example, communication converter  303  can convert the voice communication  331  in radio format  331 R into voice communication  331  in cellular format  331 C. Cellular format  331 C is compatible for transmission over a cellular network, such as, for example, a 3G cellular network, a 4G cellular network, or some other type of cellular network. Cellular format  331 C can include one or more data packets representative of the content of VHF radio communication  323  (and thus also representative of the content of voice communication  331 ). 
     Method  400  includes using wireless communication components at the Remotely Piloted Aircraft (RPA) to send the wireless communication in the other format to a control station used to control the Remotely Piloted Aircraft (RPA) via the other wireless communication network ( 403 ). For example, cellular communication components  302  (e.g., a cellular modem) can transmit the voice communication  331  in cellular format  331 C contained in cellular communication  324  over the cellular network. 
     Control station  312  can receive cellular communication  324  containing voice communication  331  in cellular format  331 C over the cellular network. Cellular components at control station  312  (e.g., a cellular modem) can process cellular communication  324  to reform voice communication  331 . Control station  312  can render voice communication  331  to pilot  311  at an audio output device, such as, headphones or speakers. 
       FIG. 4B  illustrates a flow chart of an example method  450  for transmitting wireless communication from an operator of a Remotely Operated Aircraft to a control center. Method  450  will be described with respect to the components and data of architecture  300 . 
     Pilot  311  can respond to voice communication  331 . Pilot  311  can enter voice communication  341  (e.g., can speak) into a connected audio input device (e.g., a microphone) at control station  312 . Voice communication  141  can be intended for personal at control center  309  (although others listening on the same frequency can also hear voice communication  341 ). Control station  312  can use cellular components (e.g., a cellular modem) to transmit voice communication  341  in cellular format  141 C contained in cellular communication  321 . Cellular format  341 C can include one or more data packets representative of the content of Very High Frequency (VHF) radio communication. 
     Method  450  includes using wireless communication components at a Remotely Piloted Aircraft (RPA) to receive wireless communication via a wireless communication network, the wireless communication in a format compatible for transmission over the wireless communication network, the wireless communication received from a control station used to control the Remotely Piloted Aircraft (RPA) ( 451 ). For example, cellular communication components  302  can receive cellular communication  321  from control station  312 . Cellular communication components  302  can process cellular communication  321  to access voice communication  341  in cellular format  341 C. 
     Method  450  includes using a communication converter at the Remotely Piloted Aircraft (RPA) to convert the wireless communication from the format to a radio format, the radio format compatible for transmission over a radio network ( 452 ). For example, communication converter  303  can convert the voice communication  341  in cellular format  341 C into voice communication  341  in radio format  341 R. Radio format  341 R is compatible for transmission over a radio network. 
     Method  450  includes using radio communication components at the Remotely Piloted Aircraft (RPA) to send the wireless communication in the radio format to an aircraft control center via the radio network ( 453 ). For example, a transmitter included in VHF radio communication components  304  can form electric currents representing VHF radio (e.g., airband) communication  322 . Antenna  306  can convert the electric power into radio waves. The transmitter and antenna  306  can interoperate to transmit voice communication  341  in radio format  341 R contained in VHF radio (e.g., airband) communication  322  (i.e., radio waves) 
     The radio system at control center  309  can receive VHF radio (e.g., airband) communication  322  containing voice communication  341  in radio format  341 R. 
     For example, an antenna at control center  309  can receive the VHF radio (e.g., airband) communication  322  and convert the radio waves into electric current. The electric current can be processed at a receiver included in the radio system. The receiver and the antenna can interoperate to process VHF radio (e.g., airband) communication  322  to reform voice communication  341 . Voice communication  341  can be rendered at an audio output device, such as, headphones or speakers at control center  309 . 
     Thus, RPA  301  can essentially function as a mobile communication converter capable of converting between cellular and VHF communication and vice versa. Accordingly, a two-way voice communication link can be established between pilot  311  and personnel at control center  309  even though pilot  311  is outside of control area  319  (or otherwise out of VHF radio range from control center  309 ). One part of the two-way communication link is facilitated by the cellular network and another part of the two-way communication link is facilitated by the radio network. 
     Aspects of the invention also include converting between UHF radio communication and wireless communication on other wireless networks. For example, communication converter  303  (or another similar communication converter) can be configured to convert (voice and/or data) between cellular communication and UHF radio communication and vice versa. UHF radio communication components at RPA  301  can be configured to exchange (send and receive) UHF radio communication (voice and/or data) with other systems, such as, for example, control center  309 . 
     Aspects of the invention also include conversion between VHF and/or UHF radio communications and other wireless formats, such as, satellite, Wi-Fi, WiMax, etc. 
     In one aspect, a handheld transceiver (e.g., aircraft radio) is mounted to RPA  301 . Antenna  306  can be a 5-watt hi gain antenna. Pilot  311  wears a headset and can communicate to the control center  309  through a scrambled encrypted cellular control link, up to the handheld transceiver that is within VHF range of control center  309 . This significantly increases safety for RPA  301  and other aircraft within controlled airspace. For example, pilot  311  can be in Miami while controlling RPA  301  in Los Angeles and even cause RPA  311  to enter the traffic pattern in Los Angeles. Pilot  311  can talk to a local control tower in Los Angeles via a cellular link between control station  312  and RPA  301  and a radio link between RPA  301  and the local control tower. 
     Similar mechanisms can be used for a transponder included in RPA  301 . Ground control software can include a user adjustable setting to squawk whatever (e.g., 4-digit) transponder code is either demanded from a control center (e.g., tower) or to identify the particular mission the aircraft is flying so air traffic control knows what the aircraft is doing. A transponder can include a separate circuit board attached to a 5-watt antenna but controlled through a cellular (or other wireless) link. 
     Any of a variety of different transponders can be used. For example, any of Mode A, Mode C, Mode S, Automatic Dependent Surveillance-Broadcast (“ADS-B”) can be used. 
     If the control tower says “RPA  301 , turn left heading  090 , ascend to one thousand two hundred, Squawk  1256  and ident”, the message can be transmitted via VHF to RPA  301 , converted to cellular communication at RPA  301 , and transmitted to control station  312  via a cellular network. Pilot  311  can repeat those instructions verbally to verify she or he understands them accurately. The repeated instructions can be transmitted via the cellular network to RPA  301 , converted to radio communication at RPA  101 , and transmitted via VHF to the control tower. Pilot  311  can also dial the transponder to a new code of “1256” and touch the “ident” button which essentially reacts like a sonar ping on the controller&#39;s radar screen. The onboard transponder continues transmitting that code to ground antennas and other aircraft until changed. Both air traffic control and other aircraft can then see RPA  301 . RPA  301  can be represented in radar similar to other smaller craft. 
     The transfer of radio commutation data containing the verbal instructions from the control tower, pilot  311 &#39;s response, and the transponder code can be assigned a higher priority relative to other data being routed through cellular communication components  302 . 
     RPA  101  may use various Federal Aviation Administration (FAA) transponder codes assigned specifically for use by remotely operated aircraft. For example, these transponder codes can begin with a zero and have any of three recommendations:
         0911—Emergency response missions given priority vectoring over other remotely operated aircraft flying in the airspace from 0-400′ Above Ground Level (AGL),   0060—Fast, direct routes at approximately 300′ AGL like pipeline monitoring or beach patrols.

     The transfer of radio communication data containing any of these transponder codes, as well as other transponder codes, can be assigned a higher priority relative to other data being routed through cellular communication components  302 . 
     In general, analog and/or digital systems can be used to monitor and control remotely operated aircraft (e.g., RPA  101 ). Monitoring and control equipment can be co-located with and/or separate one another. Information exchanged between remotely operated aircraft and monitoring and control equipment can be relayed over a wired and/or wireless communication networks. 
     Remotely operated aircraft can include computer network connectivity components (e.g., a Network Interface Card (“NIC”) or cellular modem) for wired or wirelessly connecting the monitoring equipment to a computer network. As such, modules, algorithms, components, etc., for controlling the flight of remotely operated aircraft (e.g., direction, speed, acceleration, pitch, yaw, roll) can also be connected to other modules, algorithms, components, etc., over (or be part of) a network, such as, for example, a Local Area Network (“LAN”), a Wide Area Network (“WAN”), and even the Internet. Accordingly, the modules, algorithms, components, etc., for controlling the flight of remotely operated aerial vehicles (e.g., direction, speed, acceleration, pitch, yaw, roll) as well as any other connected computer systems and their components (e.g., in a control center), can create message related data and exchange message related data (e.g., Internet Protocol (“IP”) datagrams and other higher layer protocols that utilize IP datagrams, such as, Transmission Control Protocol (“TCP”), Hypertext Transfer Protocol (“HTTP”), Simple Mail Transfer Protocol (“SMTP”), etc. or using other non-datagram protocols) over the network. 
     Combined Aspects 
     In some aspects, UAV  101  includes one or more of the components and functionalities depicted in and described with respect to computer architecture  300 . In other aspects, RPA  301  includes one or more of the components and functionalities depicted in and described with respect to computer architecture  100 . Accordingly, the various described aspects can be integrated together and interoperate with one another. For example, UAV  101  can facilitate wireless communication conversion between an operator (e.g., pilot) and a control center similar to RPA  301 . RPA  301  can utilize a data prioritization scheme similar to UAV  101 . 
     Aspects of the present invention may comprise or utilize a special purpose or general-purpose computer including computer hardware, such as, for example, one or more processors and system memory, as discussed in greater detail below. Aspects within the scope of the present invention also include physical and other computer-readable media for carrying or storing computer-executable instructions and/or data structures. Such computer-readable media can be any available media that can be accessed by a general purpose or special purpose computer system. Computer-readable media that store computer-executable instructions are computer storage media (devices). Computer-readable media that carry computer-executable instructions are transmission media. Thus, by way of example, and not limitation, Aspects of the invention can comprise at least two distinctly different kinds of computer-readable media: computer storage media (devices) and transmission media. 
     Computer storage media (devices) includes RAM, ROM, EEPROM, CD-ROM, solid state drives (“SSDs”) (e.g., based on RAM), Flash memory, phase-change memory (“PCM”), other types of memory, other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store desired program code means in the form of computer-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer. 
     A “network” is defined as one or more data links that enable the transport of electronic data between computer systems and/or modules and/or other electronic devices. When information is transferred or provided over a network or another communications connection (either hardwired, wireless, or a combination of hardwired or wireless) to a computer, the computer properly views the connection as a transmission medium. Transmissions media can include a network and/or data links which can be used to carry desired program code means in the form of computer-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer. Combinations of the above should also be included within the scope of computer-readable media. 
     Further, upon reaching various computer system components, program code means in the form of computer-executable instructions or data structures can be transferred automatically from transmission media to computer storage media (devices) (or vice versa). For example, computer-executable instructions or data structures received over a network or data link can be buffered in RAM within a network interface module (e.g., a “NIC”), and then eventually transferred to computer system RAM and/or to less volatile computer storage media (devices) at a computer system. Thus, it should be understood that computer storage media (devices) can be included in computer system components that also (or even primarily) utilize transmission media. 
     Computer-executable instructions comprise, for example, instructions and data which, when executed at a processor, cause a general purpose computer, special purpose computer, or special purpose processing device to perform a certain function or group of functions. The computer executable instructions may be, for example, binaries, intermediate format instructions such as assembly language, or even source code. Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the described features or acts described above. Rather, the described features and acts are disclosed as example forms of implementing the claims. 
     Those skilled in the art will appreciate that the invention may be practiced in network computing environments with many types of computer system configurations, including, personal computers, desktop computers, laptop computers, message processors, hand-held devices, multi-processor systems, microprocessor-based or programmable consumer electronics, network PCs, minicomputers, mainframe computers, mobile telephones, PDAs, tablets, pagers, routers, switches, and the like. The invention may also be practiced in distributed system environments where local and remote computer systems, which are linked (either by hardwired data links, wireless data links, or by a combination of hardwired and wireless data links) through a network, both perform tasks. In a distributed system environment, program modules may be located in both local and remote memory storage devices. 
     Aspects of the invention can also be implemented in cloud computing environments. In this description and the following claims, “cloud computing” is defined as a model for enabling on-demand network access to a shared pool of configurable computing resources. For example, cloud computing can be employed in the marketplace to offer ubiquitous and convenient on-demand access to the shared pool of configurable computing resources. The shared pool of configurable computing resources can be rapidly provisioned via virtualization and released with low management effort or service provider interaction, and then scaled accordingly. 
     A cloud computing model can be composed of various characteristics such as, for example, on-demand self-service, broad network access, resource pooling, rapid elasticity, measured service, and so forth. A cloud computing model can also expose various service models, such as, for example, Software as a Service (“SaaS”), Platform as a Service (“PaaS”), and Infrastructure as a Service (“IaaS”). A cloud computing model can also be deployed using different deployment models such as private cloud, community cloud, public cloud, hybrid cloud, and so forth. In this description and in the claims, a “cloud computing environment” is an environment in which cloud computing is employed. 
     In one aspect, one or more processors are configured to execute instructions (e.g., computer-readable instructions, computer-executable instructions, etc.) to perform any of a plurality of described operations. The one or more processors can access information from system memory and/or store information in system memory. The one or more processors can transform information between any of the described formats. 
     System memory can be coupled to the one or more processors and can store instructions (e.g., computer-readable instructions, computer-executable instructions, etc.) executed by the one or more processors. The system memory can also be configured to store any of a plurality of other types of data generated and/or transformed between any of the described formats by any of the described components. 
     The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
