This paper analyzes bandwidth allocation of Resilient Packet Ring(RPR) and proposes a new fairness algorithm which can rapidly eliminates the deviation congestion. The algorithm calculates nodes number continuously and allocates the fair bandwidth according to congestion status. Upstream nodes analyzes and calculates again after being informed of analzsis results and available bandwidth until congested nodes are found. Analyses and simulations show that RFCA algorithm is superior to AM algorithm adopted by IEEE802.17. RFCA algorithm guarantees fairness, eliminates concussion of AM algorithm, improves link utilization and has no influence on space reusability of traffic.
