This paper proposes a novel fair queuing algorithm for hybrid wired and wireless access network with wireless compensation to provide QoS bounds to Ethernet traffic. Scheduler maps priorities and weights for QoS of the Ethernet into wireless MAC. The Ethernet traffic is divided in to three flows [1-4], each flow has different requirement for loss and delay. By supporting existing Ethernet traffic, scheduler avoids the need to redefine QoS parameters for wireless channel. Real time traffic uses fair-queuing model, non real time data use weighted round robin with re-circulating queue to accommodate wireless link error. Best effort traffic use FIFO mechanism. The algorithm is adjusted for wireless link failures which are location dependent and bursty.
