Abstract:
1. A method implemented in a resilient packet ring network, comprising: measuring a current transit queue length; determining a fair rate to facilitate an allocated bandwidth in the resilient packet ring network via a PI-type controller associated with at least one node of the resilient packet ring network, wherein determining the fair rate comprises determining a difference between a target queue length and the current transit queue length; and stabilizing one or more transit queue lengths at the target queue length under unbalanced traffic scenarios, based at least in part on the allocated bandwidth, wherein determining the fair rate is based at least in part on a proportional gain k where W is a sum of weights associated with nodes of the resilient packet ring network and where τ is based at least in part on a round trip delay between a bottleneck link of the resilient packet ring network and the at least one node of the resilient packet ring network.
