摘要： A wireless access point selection system. In particular implementations, a method includes receiving a notification that identifies a wireless access point that detects radar on an operating channel and identifies the operating channel; updating neighbor lists of one or more neighboring wireless access points to remove the wireless access point from the neighbor list, where the neighbor list comprises neighbor wireless access points, corresponding operating channels, and corresponding enable indications, where each enable indication indicates if a channel availability check is required before performing active scanning; and transmitting the updated neighbor list to the neighboring wireless access points. In one implementation, a system provides a DFS enable indication to wireless clients so they can know whether a channel availability check is required prior to transmitting.

摘要： Methods, apparatuses, and systems directed to facilitating the application of pre-allocation policies in a wireless network environment. According to one implementation of the present invention, a central controller, or other control point in a wireless network infrastructure, applies one or more policies that limit the number of resource pre-allocations a given wireless client may establish with one or more wireless access points. In one implementation, the central controller provides a pre-allocation list to a wireless client that is requesting pre-allocation. By limiting a wireless client's ability to pre-allocate resources, the central controller optimally manages the resources of the wireless network. In alternative embodiments, the central controller can terminate pre-allocations between a wireless client and one or more wireless access points to enforce pre-allocation policy on the wireless network infrastructure.

摘要： Methods, apparatuses and systems facilitating containment of the effects of rogue or unauthorized access points on wireless computer network environments. Embodiments of the present invention support one to a plurality of rogue containment methodologies. A first rogue containment type involves identification of the physical connection of the rogue access point to the wired network infrastructure and, thus, allows for disabling of that physical connection to contain the rogue access point. Other rogue containment methods involve wireless techniques for containing the effect of rogue access points. As discussed below, the rogue containment functionality described herein can be applied to a wide variety of wireless network system architectures.
