Description: PERFORMANCE MANAGEMENT SYSTEM RELATED APPLICATIONS This application claims the benefit of provisional application 60/241 ,048, which hereby is incorporated by reference into this application. FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT Not applicable MICROFICHE APPENDIX Not applicable BACKGROUND OF THE INVENTION 1. FIELD OF THE INVENTION The invention is related to the field of communication systems, and in particular, to a system that provides wireless broadband services. 2. DESCRIPTION OF THE PRIOR ART People and businesses are demanding higher bandwidths from their communication providers. Consequently, the communication providers are looking for ways to increase the bandwidth of their systems using broadband technologies. Broadband technologies are generally referred to as systems that deliver a bandwidth above 64 kbps. Broadband technologies can communicate over downstream channels and upstream ch annels. The customer receives data from another device or system over the downstream channels. The customer transmits data to another device or system over the upstream channels. Broadband Wireline Systems One example of a broadband technology is Digital Subscriber Line (DSL) service. DSL service carries both voice signals and data signals at the same time in both directions. DSL service also carries call information and customer data. DSL service is typically comprised of twisted -pair wires that connect a customer to a central office. The central office comprises a Digital Subscriber Line Access Multiplexer (DSLAM) that provides the DSL service to the customer. Unfortunately, the speed of DSL service is limited by the distance between the customer an d the DSLAM. Customers located too far from the DSLAM may not be able to receive high -speed service. Also, there may not be enough customers within a particular area to make it economical to install a DSLAM. The quality of DSL service is also limited by the quality of the copper wire that connects the customer to the DSLAM. Furthermore, DSL service does not work over Digital Loop Carrier (DLC) lines. Another broadband technology is cable modem service. The cable modem communicates with a device or sys tern over a coaxial cable. The coaxial cable is typically the same coaxial cable used to receive cable television. The cable modem service can be one-way or two-way. In a two-way system, the coaxial cable carries both the upstream channels and the downst ream channels. In a one-way system, the cable modem receives data on the downstream channels over the coaxial cable and transmits data on the upstream channels over a phone line. Unfortunately, the cable modem uses up valuable bandwidth on the phone line in the one-way system. Also, the upstream bandwidth is small over a phone line. Broadband Wireless Systems Another broadband technology is wireless broadband service. Customers that subscribe to wireless broadband service communicate with a head end. In a one-way wireless system, a transmitter antenna for the head end broadcasts wireless signals to the customer on the downstream channels. The transmitter antenna is a satellite antenna or a land -based antenna. The customer transmits data to the head e nd over another medium, such as a phone line or a cable modem, on the upstream channels. One example of a one-way wireless system is a Digital Satellite System (DSS) from DIRECTV. A specific type of wireless broadband system communicates over Multichanne I Multipoint Distribution Service (MMDS) frequencies and Multipoint Distribution Service (MDS) frequencies. The MMDS frequencies range from 2596 MHz to 2644 MHz. The MDS frequencies range from 2150 MHz to 2162 MHz. In a typical MMDS system, the bandwidth of the upstream channels is about 6 MHz. The upstream bandwidth is divided into subchannels. Each subchannel has a bandwidth of 200 kHz. A head end manages the upstream and downstream channels with the customer. The head end also interfaces the custo mer with communication systems such as the Internet. The head end includes a base antenna comprised of a transmitter antenna and one or more receiver antennas. MMDS requires a line of sight between devices that are communicating. Therefore, the antennas are placed on a high building or a mountain to establish lines of sight with the customers. The transmitter antenna is omni -directional and broadcasts data from the head end to the customers on the downstream channels. In a two -way wireless system, the receiver antennas are positioned to receive MMDS signals transmitted from customers to the head end on the upstream channels. Each receiver antenna is positioned to receive MMDS signals from customers located within a certain area. The areas formed by the antennas are referred to as sectors. The sectors have designated frequency ranges or designated channels. The head end is comprised of an upstream manager and a downstream manager that control transmissions on the upstream channels and the downstrea m channels, respectively. As stated above, the upstream channels and the downstream channels are divided into subchannels. One upstream subchannel is a contention channel reserved for signaling, while the remaining subchannels are bearer channels. In the wireless broadband system, a wireless broadband router is located at a customer premises. The wireless broadband router communicates with the upstream manager and the downstream manager to exchange data. The upstream manager generally operates the cha nnels and/or subchannels in four states: idle, contention, polling, and dedicated. In the idle state, the channels are idle. In the contention state, the upstream manager generates and transmits control signals over one or more subchannels. For the polling and dedicated states, the upstream manager polls numerous wireless broadband routers to allocate use of the subchannels. Polling is a round robin process to determine which wireless broadband router has access to a subchannel. The upstream manager maintains a queue of the active wireless broadband routers to determine which wireless broadband router is next to transmit over a subchannel for a period of time. The upstream manager keeps an inventory of open subchannels and waiting wireless broadband routers in the queue. The upstream manager uses a credit to grant a wireless broadband router use of a subchannel for a limited period of time. A credit is a message that allows usage of a subchannel for a period of time or for the transfer of a maximum n umber of transmission units, such as bytes. One example of a credit is information, such as a subchannel or frequency range, a maximum allowed time to transfer data, and a maximum number of bytes the wireless broadband router is allowed to transfer. There are two kinds of credits: polling and dedicated. Polling credits are credits related to polling of the wireless broadband routers. Polling credits are generally smaller than the dedicated credits. Once the wireless broadband router completes transfer of the packets, the wireless broadband router transmits a DONE message to the upstream manager via the upstream channels. The DONE messages include information such as the number of bytes sent and the number of packets left for the wireless broadband rou ter to transfer. If the DONE message shows that the wireless broadband router has more than three packets left to transfer and there are available subchannels, then the upstream manager issues a dedicated credit to the wireless broadband router. Fault Management Systems and Performance Management Systems Two important areas in communication network operation are fault management and performance management. A fault management system assists in identifying faults in the communication network through the u se of alarms and monitoring devices. Once the fault management system identifies the faults, network personnel can then fix, replace, or add communication devices or software. Two examples of fault management systems are eHealth from Concord Communicatio ns and NerveCenter from Veritas Software Corp. A performance management system evaluates the performance of a communication network. The performance management system provides a clearer view of the operation of the communication network. The performance management system determines how a communication network is performing at all levels, such as nationally, regionally, and down to a specific communication device. Therefore, to improve performance, bottlenecks and high traffic points may be identified to add equipment or perform tuning on a specific communication device. By evaluating the performance, the performance management system can also shape the traffic over the communication network. One prior performance management system provides an Internet service assurance to e-commerce businesses for their websites. This prior system manages the delivered quality of e-mail, news, web, domain name service, Radius, file transfer protocol, and lightweight directory access protocol service of e -commerce busin esses. This prior system also provides management of service level agreements. Unfortunately, this prior system is focused on enterprise management and has not been effectively adapted for service management of a communication network. Also, this prior system does not provide performance management for operating a broadband wireless system. Remote monitoring (RMON) probes monitor performance information of a communication network. The RMON probes are in the same location as service provider equipment, which does not accurately measure from the customer 's perspective. RMON probes use RMON standards to capture and define traffic information passing through a given point. The RMON standards are divided into nine groups for Internet and a tenth group for token ring. RMON 1 is geared towards collecting datalink layer (OSI layer 2) information. The information is organized based on MAC addresses and captures datalink information such as collisions, bad packets, and link utilization. The nine groups of RMO N are statistics, history, events, alarms, hosts, matrix, topN, packet capture, and packet filter. The information is used for bandwidth allocation and for error detection. RMON 2 is concerned more with application layer information. Statistics classify each passing frame as being unicast, broadcast or multicast. Totals are kept of the number of frames passed and the utilization of the link. Each frame is also categorized by size, from 64 bytes to 1518 bytes. In addition, bad frames are counted and summary totals are created. History takes a trend analysis of the statistics explained above and presents them in a graphical or spreadsheet form. This is usually captured in increments of 30 seconds worth of traffic or more. Hosts create a table of each MAC address sending data across the line and tabulates the number of frames, good and bad, unicast or broadcast, that each MAC sends. Matrix is similar to hosts but adds in destination MAC addresses as well. Then, statistics are summarized on a per-conversation basis between any two MAC addresses. Finally, topN takes host table information and correlates to the top number of MAC addresses. The N number is generally from 5 to 10 above. An example would be to correlate the top 5 MAC addresses as pertain s to broadcasts or CRC errors. There are individual tests that measure performance of specific user 's activities. A WGET program measures the response times of Internet web surfing. Ping tests are well known to test throughput delays. Also, file transf er protocol tests measure getting and putting files from and to a web server. Unfortunately, these tests have not been effectively adapted to measure overall performance of a communication network from the customer's perspective, especially in a broadband wireless system. Unfortunately, the current broadband wireless systems have not been effectively adapted to collect, store, and report performance information for the broadband wireless systems. The current systems typically focus on collecting, storing, and reporting fault information instead of performance information. Thus, broadband wireless system providers do not have an effective way to monitor system performance.

The broadband wireless system 100 operates as follows. The customer premises' 600, 610, and 620 communicate with systems within the Internet 145. For instance, the customer premises 600 coul d download a web page from a server in the Internet 145. To download the web page, the customer premises 600 accesses the server through the head end 500, the market hub 400, and the regional aggregation point 300. The national operations centers 200 an d 210 collect network information for the broadband wireless system 100. The national operations center 200 retrieves network information from the regional aggregation point 300, the market hub 400, the head end 500, and the customer premises 600. Networ k information comprises performance information and fault information. The performance information is information that describes how a communication network is operating, such as throughput rates, number of transmission units, and signal -to-noise ratio. The fault information is information that identifies failures in a communication network, such as alarms and indicators of failed communication devices. The national operations center 200 processes and stores the network information. The national opera tions center 210 is a mirror system to the national operations center 200. The national operations center 210 retrieves and stores the same network information as the national operations center 200. Thus, if the national operations center 200 fails, then the national operations center 210 takes over without affecting the broadband wireless system 100. The regional aggregation point 300 routes data through the broadband wireless system 100 and collects network information for the broadband wireless system 100. The regional aggregation point 300 retrieves network information from the market hub 400, the head end 500, and the customer premises 600.

The market hub 400 retrieves network information from the head end 500 and the customer premises 600. The market hub 400 stores the network information and exchanges the network information with the natio nal operations center 200 and the regional aggregation point 300. The head end 500 interfaces the customer premises 600 with other components in the broadband wireless system 100 and routes data from the customer premises 600 to the market hub 400 and vice -versa. The head end 500 collects network information for the broadband wireless system 100. The head end 500 transfers the network information to the market hub 400, the regional aggregation point 300, and/or the national operations center 200. The hea d end 510 operates similar to the head end 500. The market hub/head end 520 operates similar to the market hub 400 and the head end 500. The customer premises 600 exchanges data with the head end 500 over wireless links 128 and 129. The customer premises 600 has two-way wireless communication with the head end 500 because both the downstream and upstream channels are over the wireless links 128 and 129. Those skilled in the art will appreciate that the upstream link 128 could be over a non -wireless link, such as a phone line or a cable modem, which is within the scope of the invention.

The head en d 500 communicates with the market hub 400 and the customer premises 600. The downstream manager 520 routes data to the customer premises 600. The data could be from other components in the broadband wireless system 100. The downstream manager 520 commu nicates with the other components through the switch 510 and the router 505. The operation of the router 505 and the switch 510 is well known to those skilled in the art and is not discussed for the sake of brevity. The downstream manager 520 receives p ackets that contain the data from the switch 510 over the link 513. The downstream manager 520 processes the packets to extract the data. The downstream manager 520 converts the data into an IF signal. The downstream manager 520 transmits the IF signal to the transmitter system 535 through the patch panel 525 over the links 516 and 528. The up -converter 560 and the transmitter 565 function together to process the IF signal and convert the IF signal into an RF signal. The transmitter system 535 then tra nsmits the RF signal to the transmitter antenna 570 over the link 531. The transmitter antenna 570 is an omni -directional antenna. The transmitter antenna 570 transmits the RF signal to the customer premises 600 on downstream channels over the link 129. The RF signal is a Multichannel Multipoint Distribution Service (MMDS) signal. The MMDS frequencies range from 2596 MHz to 2644 MHz. The MMDS signals in this example also include the Multipoint Distribution Service (MDS) frequencies. The MDS frequencie s comprise MDS1 (2150-2156 MHz) and MDS2 (2156-2162 MHz). The bandwidth of the downstream channels is approximately 8 Mbps. Concurrently, the upstream manager 515 routes data received from the customer premises 600 to the broadband wireless system 100. T he upstream manager 515 communicates with other components in the broadband wireless system 100 through the switch 510 and the router 505. The upstream manager 515 receives the data from the customer premises 600 through the receiver system 530 and the r eceiver antenna 575. The receiver antenna 575 is a directional antenna. The receiver antenna 575 forms a "sector" in the direction in which it points. Any communication device that communicates with the receiver antenna 575 is considered within the sect or. Those skilled in the art will appreciate that the base antenna 540 could include a plurality of receiver antennas forming a plurality of sectors. Those skilled in the art will also appreciate that the head end 500 could include a plurality of upstrea m managers and receiver systems depending on the number of sectors controlled by the head end 500. The receiver antenna 575 receives an RF signal from the customer premises 600 on the upstream channel over the link 128. The RF signal is also an MMDS signal. The bandwidth of the upstream channel is approximately 200 kbps. The receiver antenna 575 transfers the RF signal over the link 521 to the receiver system 530. The LNA 555 amplifies the RF signal. The receiver 550 and the down-converter 545 functio n together to process the amplified RF signal and convert the amplified RF signal into an IF signal. The receiver system 530 transfers the IF signal to the upstream manager 515 through the patch panel 525 over the links 517 and 514. The patch panel 525 c onnects many devices together. For instance, if the head end 500 controlled ten sectors, then the patch panel 525 would connect ten upstream managers to ten receiver systems. The upstream manager 515 receives the IF signal through the patch panel 525. The upstream manager 515 processes the IF signal to route the data carried by the IF signal. The upstream manager 515 generates packets and inserts the data, carried by the IF signal, into the packets. The upstream manager 515 transmits the packets to the switch 510 for transmission to other components in the broadband wireless system 100. The upstream manager 515 also generates control messages for the customer premises 600. The upstream manager 515 transmits these control messages to the downstream manager 520 through the switch 510. The downstream manager 520 transmits the control messages to a wireless broadband router that is located at the customer premises 600. The wireless broadband router communicates with the upstream manager and the downstream manager to exchange data. The upstream manager 515 separates the upstream channels into subchannels. The upstream manager 515 polls numerous wireless broadband routers to allocate use of subchannels. Polling is a round robin process to determine which wireless broadband router has access to a subchannel. The upstream manager 515 maintains a queue of the active wireless broadband routers to determine which wireless broadband router is next to transmit over a subchannel for a period of time. The upstream manager uses the control messages to grant a wireless broadband router use of a subchannel for a limited period of time. The control messages are credits. A credit is a message that allows usage of a subchannel for a period of time or for the transfer of a maximum number of transmission units such as bytes. One example of a credit includes information such as a subchannel or frequency range, a maximum allowed time to transfer data, and a maximum number of bytes the wireless broadband router is allowed to transfer. There are two kinds of credits: polling and dedicated. Polling credits are credits related to polling of the wireless broadband routers. Polling credits are generally smaller than the dedicated credits. Once the wireless broadband router completes transfer of the packets, the wireless broadband router transmits a DONE message to the upstream manager 515 via the upstream channels. The DONE messages include information such as the number of bytes sent and the number of packets left for the wireless broadband router to transfer. If the DONE message shows that the wireless broadband router has more than three packets left to transfer and there are available subchannels, then the upstream manager 515 issues a dedicated credit to the wireless broadband router. The receiver system 530 also receives a 10 MHz signal from the satellite receiver 587. The satellite antenna 580 receives satellite signals and transmits the satellite signals to the satellite receiver 587 over the link 524. The satelli te receiver 587 processes the satellite signals to generate the 10 MHz signal. The satellite receiver 587 transmits the 10 MHz signal to the receiver system 530 over the link 526. The receiver system 530 uses the 10 MHz signal as a reference signal. In some examples, the receiver system 530 communicates with the receiver antenna 575 over the links 522 -523 and the O/E converter 585. In this example, the link 522 is a fiber optic cable. Depending on the number of receiver antennas on the base antenna 540, the number of wire cables, such as the link 521 , running from the base antenna 540 could become large. A large number of wire cables can be heavy and can add stress to the structure of the base antenna 540. Conversely, fiber optic cable can be lighter than wire cable. Therefore, it may be advantageous to run fiber optic cable between the base antenna 540 and the receiver system 530. In such a case, the O/E converter 585 is used to convert the optical signal to an electrical signal.

Those skilled in the art will appreciate numerous variations in a sector probe configuration and operation that are within the scope of the invention. Those skilled in the art will also appreciate how the principles illustrated in this example can be used in other examples of the invention. In this embodiment, the sector probe 695 measures the performance of the broadband wireless system 100 by simulating web surfing of the top ten websites, transferring files using File Transfer Protocol (FTP), and using a ping test to measure delay. Typically, there is one secto r probe per sector, and a head end typically controls eight to ten sectors. With two head ends per market, there are between sixteen to twenty sector probes per market. FIG. 10 is a flow chart for the sector probe 695 with web surfing, FTP, and delay tests in an example of the invention. FIG. 10 begins in step 1000. The sector probe 695 receives and processes an instruction to execute a plurality of tests. In step 1002, the sector probe 695 executes a WGET program for web surfing. Step 1002 and the WGET program are discussed below in greater detail in FIG. 11. In step 1004, the sector probe 695 executes a bulk file transfer script. Step 1004 and the bulk file transfer script are discussed below in greater detail in FIG. 12. In step 1006, the sector probe 695 executes a ping test to measure delay. Step 1006 and the ping test are discussed below in greater detail in FIG. 13. In step 1008, the sector probe 695 executes a raw channel capacity test. In this embodiment, the raw channel capacity test i s a New Test TCP (NTTCP) program to simulate bit -error-rate testing over the wireless links 128 and 129. The NTTCP program is an open source software package that transmits a flood of unacknowledged packets over a link and measures the number of received packets versus the number of dropped or corrupted packets. The NTTCP program assists in determining the general condition of the wireless links 128 and 129. In step 1010, the sector probe 695 executes an out of lock indicator test. The out of lock indicator test indicates the presence of a clean Quadrature Amplitude Modulation (QAM) signal. If the modem, within the wireless broadband router 690, goes out of lock, then there is an RF interference in the air or a bad component in a piece of the equipment . In step 1012, the sector probe 695 executes a downstream FEC test. The FEC test detects FEC errors that indicate dropped packets. In step 1014, the sector probe 695 stores the results of the tests of steps 1002 -1012 in the memory 830. FIG. 10 ends in step 1016. FIG. 11 is a flow chart for the sector probe 695 for a web surfing test in an example of the invention. FIG. 11 begins in step 1 100. In step 1102, the sector probe 695 measures the start time of the WGET program. The WGET program is an open - source program used to transfer a single file over a HyperText Transfer Protocol (HTTP) connection from a server. In this embodiment, the sector probe 695 executes the WGET program for ten popular websites such as Yahoo, ESPN, and MSN. In step 1104, the sector probe 695 transmits a request for the ten popular web pages. In step 1106, the sector probe 695 receives the ten popular web pages.

The ping test is a standard TCP/IP utility to measure the round trip time b etween two hosts. The ping test also can measure the time between two endpoints on a link and the average delay of packets on that link. This ping test transmits eleven pings at one -second intervals. In step 1302, the sector probe 695 measures the start time of the ping test. In step 1304, the sector probe 695 transmits and receives one ping. In step 1306, the sector probe 695 measures the delay of the one ping to measure the time to acquire a spot in a polling channel. This delay indicates the speed at which a transmission begins. A first ping is measured separately because the time to acquire a spot in the polling channel will be longer than future credit reception cycles. One example of delay for one ping is shown in FIG. 46, which is discussed be low. In step 1308, the sector probe 695 transmits and receives ten pings. In step 1310, the sector probe 695 measures the delays of the ten pings. The sector probe 695 determines the average delay of the ten pings to determine the average roundtrip time once the wireless broadband router 690 has been admitted to a polling group. This delay indicates the customer 's experienced speed on most downstream transfers excluding the shortest downstream transfers. One example of the average delay for ten pings is shown in FIG. 46, which is discussed below. In step 1312, the sector probe 695 then compares the delay for the first ping with the average delay of the last ten pings. In step 1314, the sector probe 695 measures the end time of the ping test. FIG. 13 ends in step 1316. Channel Probe - FIGS. 14-16 Upstream managers and downstream managers in a broadband wireless system manage upstream and downstream channels, respectively.
