    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 location or containment 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. In some embodiments, the present invention provides methods, apparatuses and systems facilitating network location of rogue access points to determine whether one or more rogue containment methodologies should be applied. As discussed below, the rogue location and containment functionality described herein can be applied to a wide variety of wireless network system architectures.

    摘要： Methods, apparatuses, and systems directed to facilitating roaming and client handoffs in wireless networks. In one implementation, the present invention is directed to a coordination mechanism facilitating handoffs of wireless clients in a wireless network infrastructure. In one implementation, the coordination mechanism minimizes the use of group- or multi-casting to provide a scalable wireless network roaming infrastructure.

    摘要： In a fixed channel wireless network system with a limited number of channels, assignment of the fixed channels between remote client elements and access elements is made systematically according to a set of criteria accounting for network loading and interference, then channel assignments are dynamically updated according to a priority to maintain optimal network performance with changing conditions of load and interference. The channel utilization problem is address at a system level rather than at a local level by treating the system as a three dimensional color mapping problem. All noise is treated as having a source in virtual access elements with an appropriate performance metric. The performance metric is used to select a channel set that minimize chances of interference and maximize user performance. Specifically, there are several parameter matrices which are managed and updated by a central resource management element, namely signal strength between elements, interference, and load. These matrices are used to find the optimal channel assignments for a predetermined limited set of assignable channels.
