摘要
Congestion across links in a network, such as the Internet, is reduced by diverting traffic from the congested link to alternative, shortest paths by adjusting splitting factors associated with the congested and alternative links. The alternative shortest paths comprise equal cost paths. Alternatively, adjustments occur after the creation of additional equal cost paths/shortest paths if none are initially available within the network. Unique programs control the adjustment of the splitting factors and the creation of the additional shortest paths. The programs make use of both existing, real networks and constructed, virtual networks in conjunction with novel traffic flow relationships to divert traffic from a congested link without causing further congestion within the network. Another unique program deletes shortest paths once used to accept traffic diverted from a congested link when traffic in the network decreases.
