Abstract:
1. A method of implementing load balancing in a resilient packet ring (“RPR”) network comprising a plurality of nodes and first and second rings each comprising a plurality of links for carrying information between the nodes in a clockwise direction and a counterclockwise direction, respectively, wherein adjacent ones of the nodes are connected by two of the links, the method comprising the steps of, for one of the nodes: determining whether a load imbalance exists at the node in connection with a first class of service, using a technique selected from the group consisting of measuring and comparing delays experienced by a marked packet sent from the node to a second node via the first and second rings, respectively, and comparing a number of dropped packets on the first and second rings with a preselected maximum value; and responsive to a determination that a load imbalance exists:
