摘要： A method and device for providing switched tunnel connections from a user to a destination or a multiple number of destinations. Tunnels are switched from a user to a destination by receiving an incoming tunnel connection from the user and initiating a switched tunnel connection to the destination. Traffic from the incoming tunnel is switched to the destination over the switched tunnel. A disclosed embodiment uses user information to determine the switching of the tunnel to implement security access to a tunnel destination, load balancing among destination resources, and bundling of tunnel sessions to implement high bandwidth transmission.

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.
