Abstract
A computer network includes a plurality of routing nodes, each routing node being connected to selected ones of the other routing nodes and at least some of the routing nodes being connected to one of a plurality of packet sources or one of a plurality of packet destinations. Each routing node routes packets that are generated by the packet sources to respective ones of the packet destinations, each packet including a plurality of serially-transmitted cells. At least some of the routing nodes, in response to detection of a selected degree of congestion, enable an "early packet discard control arrangement," in which they discards cells which they receive which are related to packets for which they did not receive a cell prior to enabling the early packet discard control arrangement. The routing nodes periodically adjust the degree of congestion at which they will activate the early packet discard mechanism in relation to information corresponding to rates of reception and transmission of cells over a selected period of time prior thereto.
