Abstract
A method of bandwidth allocation in a Resilient Packet Ring (RPR) network includes: congestion degree of a present node in the RPR network is determined. There is an upstream node and a downstream node of the present node in the RPR network. A present local arrival rate of local traffic flows of the present node from at least one client is obtained. An average transit rate of fairness eligible (FE) flows of the present node in a past time period is calculated. An effective node number for the present node and a present temporal fair rate of the present node are calculated respectively. A present local fair rate of the present node is obtained by looking up a local fair rate table. Transit rate transmitted by the upstream node is controlled according to the present local fair rate of the present node.
