Abstract
A method and system for aggregating a plurality of parallel communications links transmitting data between adjacent nodes in a network is provided. The method simplifies network topology by replacing multiple parallel communications links between nodes in the network with a single aggregated link. The method advertises the available bandwidth of each aggregated link to the network, the available bandwidth being the maximum bandwidth available for any one of the parallel links in the aggregate. The method permits each aggregated link to select which of the parallel links in the aggregate is to be used to transfer data from one node to the other. Aggregating links can be automatic and based on one or more predetermined criteria, such as the service class supported by the parallel links.
