摘要： A data processing system and method are described for permitting a server computer system to remotely disable an ability of a client computer system to access a network which couples the client computer system to the server computer system. The server computer system transmits an indication to the client computer system utilizing the network that the ability of the client computer system to access said network be at least temporarily disabled. In response to a receipt of the indication by the client computer system, the ability of the client computer system to access the network is at least temporarily disabled. The client computer system is unable to transmit information utilizing the network while the client computer system is temporarily disabled.

摘要： 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.

摘要： 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.
