ABSTRACT:
A system and a method is disclosed for setting up, modifying and tearing down a down-stream communication session in a basic service set (BSS) in a wireless local area network (WLAN) such that the communication session has a defined quality of service (QoS) Regarding setting up a down-stream communication session, a first Path message and a first Resv message (Path/Resv message) of a RSVP protocol are detected at a designated subnet bandwidth manager (DSBM) in a station having a point coordinator (PC). The first Resv message originates from a subnet bandwidth manager (SBM) of a non-PC station in the BSS, and requests a resource reservation for setting up a down-stream session between the PC station and at least one destination non-PC station in the BSS.
