RSVP/SBM based side-stream session setup, modification, and teardown for QoS-driven wireless LANs

摘要

A method and a system are disclosed for setting up, modifying and tearing down a side-stream communication session in a basic service set (BSS) in a wireless network so that the communication session has a defined Quality of Service (QoS). Regarding setting up a side-stream communication session, a first Path message and a first Resv message (Path/Resv message) of a RSVP protocol is detected at a designated subnet bandwidth manager (DSBM) in a station having a point coordinator (PC). The first Resv message originates from a RSVP agent of a destination non-PC station in the BSS and requests resource reservation for setting up a side-stream session between a source non-PC station and at least one destination non-PC station in the same BSS. The DSBM extracts a QoS parameter set and a classifier from the first Path/Resv message for the session.
