Selective load redistribution in packet-switched networks

A design is presented for rerouting existing sessions (virtual circuits) under certain conditions to improve the routing performance. The authors call this mechanism selective load redistribution (SLRD). SLRD is a fully distributed algorithm which redistributes sessions in parallel at different nodes by carefully selecting the amount of traffic to be switched. The performance of the algorithm is evaluated by a simulation model. The results for several sample networks show that the algorithm performs very well even though the information available to the nodes for route computation may not be completely accurate.<
