A fuzzy fairness control mechanism in resilient packet ring

In recent years, the high increasing volume of data traffic is challenging the capacity limit of existing Internet infrastructures. The RPR is intended to enable the creation of high-speed networks for packet transmission in ring topologies. An effective and feasible fairness control mechanism is indispensable to enhance the network utilization. In this paper, a fuzzy fairness control mechanism (FFCM) is proposed to detect and prevent the congestion problem by allocating the network resources adaptively. Simulation results show that the performance of the FFCM is much better than the performance of the aggressive mode (AM). FFCM improves the network utilization by about 20% than AM. Consequently, we can conclude that the FFCM is an effective and feasible fairness control mechanism.
