Abstract
Resilient Packet Ring (RPR), defined by the IEEE 802.17 working group, is a new solution to metropolitan area network. RPR adopts the packet-based dual ring structure so that it can provide the protection capability similar to the SDH as well as dynamic bandwidth allocation. The design of fairness control mechanism to allocate the bandwidth is a key problem for RPR. Currently, two different modes of fairness algorithm have been proposed in the RPR standard, the aggressive mode (AM) and the conservative mode (CM). However, there are several limitations for these modes, such as the amount of the bandwidth allocated oscillates permanently under unbalanced traffic scenarios. In this paper, we propose a novel fairness control mode. The simulation experiment shows the range of traffic oscillation controlled by our mode is significantly damped compared to current RPR algorithm.
