摘要： Data distribution between mobile stations and external data paths is assigned to a new set of devices, distribution points. Each distribution point is independently coupled to mobile stations, also assigned to access points. Control elements operate to control the distribution points separately from the access points. Each access point maintains a substantially stateless link with each distribution point for which the two share a mobile station. Access points might exchange data with any one or more distribution points concurrently. Access points thus obtain greater bandwidth connectivity to external data paths. Mobile stations transfer between access points and transfer between distribution points independently. This has the effect that bandwidth connectivity between distribution points and external data paths have no particular requirement for VLAN separation. Mobile stations may roam among multiple Internet protocol subnets.

摘要： AP's associated with a communication network and any wireless devices desiring contact, operated according to a protocol in which each wireless device selects AP's with which to communicate. A system coordinator causes the AP's to operate so as to guide each wireless device to an AP selected by the system coordinator. This has the effect that, notwithstanding that the protocol involves having the wireless device make the selection of AP, functionally, the AP's make the selection for it. In a 1st technique, multiple AP's share an identifier, with the system coordinator directing one particular AP to respond to the wireless device, thus appearing to wireless devices as a “personal cell”. In a 2nd technique, AP's each maintain identifiers substantially unique to each wireless device, with the system coordinator directing only one particular AP to maintain any particular wireless device's identifier, thus appearing to wireless devices as a “personal AP”.

摘要： A communication system detects particular application protocols in response to their message traffic patterns, which might be responsive to packet size, average packet rate, burstiness of packet transmissions, or other message pattern features. Selected message pattern features include average packet rate, maximum packet burst, maximum future accumulation, minimum packet size, and maximum packet size. The system maintains a counter of packet tokens, each arriving at a constant rate, and maintains a queue of real packets. Each real packet is released from the queue when there is a corresponding packet token also available for release. Packet tokens overfilling the counter, and real packets overfilling the queue, are discarded. Users might add or alter application protocol descriptions to account for profiles thereof.

摘要： Flows are grouped into flow classes, each of which is assigned flow class treatment rules, which might combine application of both firewall and QoS treatments. When a flow is identified as a member of a flow class, traffic for that flow can be treated according to treatment rules collectively with other flows assigned to that flow class. New flows not already members of an already-defined flow class are examined according to a set of flow class assignment rules, which have the effect of either identifying the proper flow class for that flow, or creating a new flow class for that new flow. For each flow, a first packet determines flow assignment, after which succeeding packets are treated according that flow. For each flow class, a first flow determines flow class assignment, after which succeeding flows are collectively treated according to that flow class.
