Abstract

Method and apparatus providing for load sharing in redundant communication networks. The method and apparatus may include detection of redundant communication links in the network topology and sharing communication load over those links. This may be accomplished through assignment of unique labels to each link in a group of redundant links and assignment to each data packet of a value corresponding to the label on just one of the links; the packet being forwarded on only that link. The method and apparatus are also suited to quick recovery from a change in state of a network topology.
