ABSTRACT:
A technique for controlling a packet data network to maintain network stability and efficiently utilize network resources through mechanisms involving per-destination queues and urgency weights for medium access control. The technique jointly controls congestion, scheduling, and contention resolution on hop-by-hop basis, such that the length of queues of packets at a node does not become arbitrarily large. In one embodiment, queue lengths and urgency weights may be transmitted and received via medium access control messages.
