Abstract
A wireless network access device includes a radio and support for virtual access points. According to the invention, each virtual access point has an independently configurable quality-of-service profile. The per-VAP QoS support enables multiple services to be delivered from a single physical access point. A plurality of transmit/receive queues are associated with each virtual access point (VAP) configured on the access device. Each queue in the plurality of queues is associated with a given quality-of-service level, such as (in decreasing order of priority): voice, video, best effort data, and background data. The access device further includes a data transfer mechanism in the form of a data packet forwarding engine that, for each VAP, transfers data from the plurality of queues to enforce the per-VAP QoS policy.
