    Abstract: Apparatus and method provides dynamic load balancing of network bandwidth between access points in an 802.11 wireless LAN. The access point generates and monitors average bandwidth utilization of client devices connected to said access point. The average bandwidth utilization for each client device is aggregated and selected clients are forced to roam to other access points if the aggregate bandwidth is equal or exceeds a threshold.

    Abstract: A system and method for autonomic wireless presence ping is presented. An IS administrator wishes to collect capacity requirement information corresponding to a wireless network, such as the number of packets a client sends to and receives from an access point. The IS administrator sends a request to the access point. In turn, the access point sends a control packet to client devices it supports, instructing them to enable an enhanced presence ping bit. Each client enables its enhanced presence ping bit, and collect enhanced status information. Each client device sends the enhanced status information to the access point either when a timer expires, or when the client device receives a ping request from the access point. The access point then forwards the enhanced status information to the IS administrator for analysis.

    Abstract translation: 提出了一种用于自主无线存在ping的系统和方法。 IS管理员希望收集对应于无线网络的容量需求信息，例如客户端从接入点发送和接收的分组数量。 IS管理员向接入点发送请求。 反过来，接入点向其支持的客户端设备发送控制包，指示他们启用增强的存在ping位。 每个客户端使其增强的存在ping位，并收集增强的状态信息。 当定时器到期时，或当客户端设备从接入点接收到ping请求时，每个客户端设备将增强状态信息发送到接入点。 接入点然后将增强状态信息转发给IS管理员进行分析。

    Abstract: A wireless network access point is described which provides the resources of a backbone network to wireless clients. The access point is able to detect a degraded condition on the backbone network. Upon detecting the degraded condition, the access point transmits or broadcasts a reassociation request to one or more clients associated with the access point. In addition, the rate at which new associations are made is halted or reduced during the degraded backbone condition. In one embodiment, the association rate is reduced by increasing the interval between beacons transmitted by the access point which identify the access to the backbone network.

    Abstract: In accordance with the preferred embodiment, an access point provides dynamic load balancing of network bandwidth between access points within the 802.11 wireless LAN. The access point uses the RTS/CTS protocol to reduce the bandwidth available to a single device using an excessive amount of network bandwidth. The access point places a device that has been monopolizing a network channel on a Restricted List, and regulates bandwidth on the network by not returning a CTS to any client on the Restricted List. When the client's network usage drops below a policy driven threshold set by the number of network users, the client is removed from the list and the access point will respond to a RTS from the client with a CTS.
