Spatial Reuse and Fairness in Resilient Packet Ring

摘要

The recent increase in the transmission speed and bandwidth has resulted in the emergence of new networking solution, Resilient Packet Ring. In this paper, we firstly study the spatial reuse protocol in Resilient Packet Ring. Then based on node model, we discuss several access control mechanisms, including traffic shaping and Virtual Destination Queuing. Finally, a new effective fairness algorithm is presented. In order to ensure the requirement of high priority traffic and avoid high priority traffic taking up all of capacities, the algorithm proportionally assigns the fair rate to different traffic in a theoretical optimal way according to the service priority.
