Active Queue Management for MAC Client Implementation of Resilient Packet Rings

The IEEE 802.17 is a standardized ring topology network architecture, called the resilient packet ring (RPR), to be used mainly in metropolitan and wide area networks. This paper focuses on the RPR MAC client implementation of the IEEE 802.17 RPR MAC in the aggressive mode of operation and introduces a new active queue management scheme for ring networks that achieves higher overall utilization of the ring bandwidth with simpler and less expensive implementation than the generic implementation provided in the standard. The scheme introduced in this paper provides performance comparable to the per destination queuing implementation, the best achievable performance.
