Abstract
Techniques for bandwidth management and flow control on a resilient packet ring (RPR) network is described. The RPR requires allocation and guarantee of a bandwidth for each channel between two nodes on the ring. The bandwidth is managed by shaping traffic on a channel at the source by using a bandwidth allocation factor calculated at each node. The bandwidth allocation factor, which is communicated to other nodes, is calculated by using a recursive nonlinear function of the transit buffer size.
