摘要： A technique for implementing AP-local dynamic switching involves Layer 2 switching. This may be accomplished by providing data associated with wireless stations to an AP sufficient to enable the AP to determine whether traffic from a particular wireless station should be locally switched. Alternatively, the wireless station may be able to determine whether to locally switch traffic based upon the traffic itself. For example, it may be desirable to AP-locally switch voice traffic to avoid latency, which is particularly detrimental to voice transmissions such as voice-over-IP. Traffic that is not to be switched locally is Layer 2 tunneled upstream.

摘要： A technique for providing a prediction as to whether a resource will be accessible to a user is described. The technique can involve comparing asserted membership in a wireless realm with membership records. Advantageously, a user can be made aware of the likelihood of access to a resource before attempting to reach the resource.

摘要： Systems and methods for network assignment based on priority are described in this application. In one aspect, a technique for network assignment based on priority relates to establishing a connection between a client and a virtual local area network (VLAN), based on an explicit or implicit network priority preference of the client. In an embodiment, multiple VLANs can be combined into one network bundle, the network bundle being a unit network for priority specification. In addition, multiple network bundles may be available for network assignment on a particular network controller (e.g., network switch). For example, the preferred network of a client may be comprised of several individual VLANs. Thus, the client can be assigned to any of the constituent VLANs included in the preferred network bundle.

摘要： A technique for implementing an untethered access point (UAP) mesh involves enabling AP-local switching at one or more UAPs of the mesh. A system constructed according to the technique may include a wireless switch; an access point (AP) wire-coupled to the wireless switch; and a UAP mesh, wirelessly coupled to the AP, including a UAP with an AP-local switching engine embodied in a computer-readable medium. Another system constructed according to the technique may include an untethered access point (UAP), including: a radio; a backhaul service set identifier (SSID) stored in a computer-readable medium; an anchor access point (AAP) selection engine embodied in a computer-readable medium. In operation, the AAP selection engine may use the radio to attempt to associate with the AAP if a beaconed backhaul SSID matches the stored backhaul SSID. A method according to the technique may include beaconing with a backhaul SSID; acting in concert with an upstream switch as an authenticator for a downstream station that responds to the beacon; providing limited local switching functionality for the downstream station.

摘要： A technique for controlling the amount of power consumed by access points (APs) of a wireless network involves implementing throttleable APs (TAPs). It would be desirable for the TAPs to be in a relatively low power mode during periods of low activity, and switch to a high power mode in response to increased wireless activity. To that end, a throttling engine can be implemented to throttle TAPs up in power in response to increases in wireless activity, and throttle TAPs down in power in response to decreases in wireless activity.

摘要： A technique for wireless network monitoring involves scanning channels using clients instead of access points. An example of a method according to the technique may include, for example, receiving from a wireless access point a command to perform a channel scanning function, listening on a channel associated with the channel scanning function, and sending RF data found on the channel to the wireless access point. Another example of a method according to the technique may include, for example, scanning a first channel, switching from the first channel to a second channel, sending data on the second channel to an access point, switching from the second channel to the first channel, and resuming scanning on the first channel. A system according to the technique may include one or more scanning clients, proxy clients, multi-channel clients, or other clients that are capable of scanning channels in lieu of an access point.

摘要： A technique for controlling the amount of power consumed by access points (APs) of a wireless network involves implementing power-saving APs (PSAPs). It would be desirable for the PSAPs to be in sleep mode during periods of low activity, and at full power during periods of high activity. To that end, a PSAP agitation (PSAPA) engine can be implemented to agitate PSAPs in response to increases in wireless activity, and put PSAPs to sleep in response to decreases in wireless activity.

摘要： A technique for improving authentication speed when a client roams from a first authentication domain to a second authentication domain involves coupling authenticators associated with the first and second authentication domains to an authentication server. A system according to the technique may include, for example, a first authenticator using an encryption key to ensure secure network communication, a second authenticator using the same encryption key to ensure secure network communication, and a server coupled to the first authenticator and the second authenticator wherein the server distributes, to the first authenticator and the second authenticator, information to extract the encryption key from messages that a client sends to the first authenticator and the second authenticator.

摘要： A technique for locating a device uses connectivity to find a distance between an access point (AP) and a device. The AP transmits a frame to a device and receives an acknowledgement frame from the device. The amount of time for a signal to pass between the AP and the device is estimated and multiplied by the speed of light to find the distance between the AP and the device.

摘要： A novel technique involves evaluating a real-time environment of a channel based on a nonlinear function of the number of neighbor radios and channel utilization requirements. The technique can be used to pick a channel for an AP that is added to a wireless network or to tune a channel for an existing AP. The technique can be applied to, for example, a relatively new wideband option in the 802.11n standard.
