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： In a wireless Local Area Network (WLAN) system, a hierarchical architecture is provided which employs a protocol which divides protocol processing functions between a plurality of substantially identical access elements in which reside time-critical protocol functions, such as acknowledgment and retransmission of packets, and a centralized control element which provides control and management functions related to dynamic configuration of wireless networks, such as processing of network management messages (e.g., authentication and association), load control, channel control, and handoff, processing of physical layer information, and processing of channel characteristics, propagation, interference or noise, for the plurality of access elements on the WLAN without loss of information about the wireless characteristics of the access elements. This hierarchical protocol processing architecture allows the data flow to be centralized for better performance and provides useful access to all the protocol information from the WLAN.

摘要： Methods, apparatuses, and systems directed to a key distribution and caching mechanism that facilitates roaming in wireless networks. In one implementation, the present invention reduces the latency associated with handoffs by reducing the time required to set up encryption or other secure access mechanisms between access points and clients in the wireless network infrastructure. In one implementation, the present invention operates proactively to distribute authentication credential information to selected components of the wireless network infrastructure before a client roams to another access point.

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.
