Configurable wireless switched network

A configurable wireless switched network includes a wireless access point. The wireless access point includes an application that is executable thereon. The application is configured to set, by a user via an input component, a first port of a plurality of ports as a command channel. The command channel provides a first point of contact between the wireless access point and client devices. The application is also configured to receive configuration parameters from the user. The configuration parameters include port allocation instructions for the ports and identifiers of the client devices. The application is further configured to monitor bandwidth utilization on a network; receive, at the command channel, a request from one of the client devices to access the network; and assign one of the ports to the client device based on the port allocation instructions, the bandwidth utilization, and an identifier of the client device.

BACKGROUND

The present invention relates to wireless networks, and more specifically, to a configurable wireless switched network.

Wireless routers, also referred to as wireless access points and switches, are very often used in networking configurations, such as local area networks. Wireless routers, may be single- or dual-band capable, and may support a number of wired connections through its ports (also referred to as channels). Wireless routers typically use one channel (or two in the case of a dual-band router) to share all wireless access to the router.

In a home environment, at one time there may be heavy streaming of content to devices that require large amounts of bandwidth and at another time there may be very little bandwidth consumption among the devices. Thus, the bandwidth utilization at any given time can vary significantly with respect to network devices.

According to embodiments of the present invention, a configurable wireless switched network includes a wireless access point. The wireless access point includes a plurality of ports; an input component; a memory unit; a computer processor communicatively coupled to the plurality of ports, the input component, and the memory unit; and an application. The application is operable to set, by a user via the input component, a first port of the plurality of ports as a command channel. The command channel provides a first point of contact between the wireless access point and client devices communicatively supported over a network by the wireless access point. The application is also configurable to receive configuration parameters from the user.

DETAILED DESCRIPTION

In accordance with exemplary embodiments, a configurable wireless switched network is provided. Wireless switched networking processes enable a wireless access point (WAP) or router to act as a multi-mode switched/shared device using channels as set ports. The wireless switched networking processes enable an end user or administrator to configure channels on their wireless router to act as switched ports by chaining specific devices to set channels, or by setting the channels aside for the router to automatically negotiate a unique channel for an individual client to use as a port. In addition, the wireless switched networking processes allow for any individual channel to be set up (or set aside) for implementation in normal, ‘shared’ mode, thus allowing for the end user to set up certain classes of clients to share a port, while servers needing increased bandwidth, such as home media or file servers, can attach to their own individual ports.

Turning now toFIG. 1, a system upon which wireless switched networking may be implemented will now be described in accordance with some embodiments.

The system100includes a wireless access point (WAP)102and client devices104A,104B, and104C (collectively referred to as “104”), which together form part of a network, such as a local area network.

The WAP102includes ports (also referred to as channels)106. One of the ports is designated as a command channel108, as will be described further herein. The ports106enable network access for the client devices104A,104B, and104C.

The client devices104may be implemented as any type of communication device with processing and network communication capabilities. As shown inFIG. 1, for example, client device104A is a laptop, client device104B is a desktop or general-purpose computer, and client device104C is a portable device, such as a tablet PC or smart phone. The client devices104may be any combination of wired and/or wireless communication devices. In one embodiment, at least one of the client devices104is connected to the WAP102via physical wiring, and at least one of the client devices104is wirelessly connected to the WAP. In an embodiment, the client devices104may operate logic embedded on corresponding network device drivers (not shown) to facilitate configuration of the ports106.

The WAP102includes a computer processor (CPU)110, an input component112, a memory unit114, and at least one antenna116. The input component112may be implemented as one or more physical buttons, knobs, or switches. A user, such as an operator of any of the client devices104may configure the ports106via the input component112. In one embodiment, at least a portion of the configuration of the ports may be implemented via the client devices104(e.g., through the logic embedded on the network device drivers).

The antennae116may be implemented to conform to current wireless communication standards, e.g., IEEE 802.11. The memory unit114may store an application118and parameters120for use in implementing the exemplary wireless switched networking processes described herein. The computer processor110executes the application118to receive parameters from a user of the network and to assign ports to client devices104, as will be described further herein.

The parameters120include allocation instructions selected or created by the user. The parameters120may be non-negotiable, such that an assignment of a client device to a port is carried out regardless of other conditions or activities experienced on the network. In this embodiment, the assignment may be directed to a shared port or an individual port. For example, a parameter120may be a dedicated port assigned to a particular client device104. Likewise, a parameter120may be a shared port that is assigned for two or more client devices104. The port may be assigned based on a client device identifier that is determined by the application118when the client device attempts to gain access to the network.

Alternatively, or in addition, thereto, the parameters120may include negotiable elements, such that an assignment of a client device to a current port is renegotiated based on various conditions, such as identification of a peak throughput pattern of bandwidth utilization or a threshold value of bandwidth utilization set via the parameters. In this embodiment, when a specified condition is met, the renegotiation may result in reassignment of the client device from its current port to a different port on the WAP102. To illustrate further, the following scenarios are provided:

Example A describes dynamic renegotiation of a client device into an individual (non-shared) port. In this example, the client device surpasses a clip level (threshold bandwidth) utilization, and the application118negotiates with the client device104to move the client device's connection over to an individual port. The connection is moved, and the client device104is now on a switched individual port.

Example B describes a client device configured for direct attachment to an individual port of the WAP102. In this example, a user (e.g., administrator) configures the WAP102to always supply an individual (non-shared) port to a specified client device. The client device attaches to the WAP102through the command channel108. The WAP102negotiates with the client device to move the client device's connection over to an individual (non-shared) port. The connection is moved, and the client device is now on a switched individual port.

Example C describes dynamic renegotiation of a client device into a shared pool port. In this example, the client device, which was previously dynamically attached to an individual port, hits a fallback clip level (i.e., bandwidth utilization decreases). The WAP102negotiates with the client device to move the client device's connection over to a shared port. The connection is moved, and the client device is now on a port that is part of a shared pool.

Turning now toFIG. 2, an exemplary process for implementing the configurable wireless switched networking will now be described.

At block202, at set up process begins. A user sets one port of the WAP102as the command channel108. As indicated above, the command channel provides a first point of contact between the WAP102and client devices communicatively supported over a network by the WAP102.

At block204, the application118receives configuration parameters120from the user. The configuration parameters120include port allocation instructions for the ports106and may also include identifiers of the client devices. The port allocation instructions and the identifiers may be stored in the memory unit114.

At block206, the application118monitors bandwidth utilization of the network. At this point, the process ofFIG. 2includes two separate branches, which may or may not be simultaneously implemented. One of the paths is directed to handling a request from a client device looking to access the network, while the other path is directed to dynamic renegotiation of assignments based on results of the network monitoring. The first path is described in blocks208-212, and the second path is described in blocks214and216.

At block208, the command channel108receives a request from a client device104to access the network. At block210, the application applies port allocation instructions to the client device. For example, if the port allocation instructions provide that a particular client device use a dedicated port, then the application118follows the port allocation instructions accordingly. Thus, at block212, the client device is assigned to a port based on the application of the port allocations instructions. In one embodiment, the assignment may further consider the bandwidth utilization information resulting from the monitoring in performing the assignment, if desired. The process returns to block206.

Returning to the second path ofFIG. 2, the application118determines if a threshold bandwidth utilization level has been met. For example, the configuration parameters120may include a maximum threshold utilization pattern, which when detected from the network monitoring over time, causes the application118to dynamically renegotiate assignment of at least one of the client devices to a dedicated port. Likewise, the configuration parameters120may include a minimum threshold bandwidth utilization pattern, which when detected from the network monitoring over time, causes the application118to dynamically renegotiate assignment of the client device to a shared port. The reassignment may be implemented immediately (e.g., on determination that the client device is outside of the threshold utilization value) or may be implemented upon reconnection of the client device to the network.
