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 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： A congestion control system. In particular implementations, a method includes receiving packets into one or more queues and monitoring the one or more queues for congestion. The method also includes, if a number of packets in the one or more queues exceeds a first threshold, determining a congestion control mode. The method also includes generating a congestion control message indicating the congestion control mode and transmitting the congestion control message to one or more neighboring mesh nodes.

摘要： A troubleshooting system. In particular implementations, a method includes collecting, from a first wireless network element, PEM state associated with a wireless client having a connection problem, and collecting log data associated with the wireless client from the first wireless network elements and one or more other wireless network elements. The method further includes correlating the PEM state and log data based on a network security protocol employed by the wireless client, where the network security protocol corresponds to an expected sequence of events. The correlating includes correlating events and messages collected based on the expected sequence of events, and comparing the correlated sequence of events to a data store of diagnostic information to identify one or more possible causes of the connection problem.

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.
