Abstract
A switching fabric uses traffic congestion information to inform its opportunistic use of non-minimal routes. An ingress port of a network switch collects traffic congestion information from the egress ports of the network switch. The traffic congestion information includes minimal and non-minimal route congestion metrics for the egress ports. Candidate egress ports for forwarding a packet to a destination node are identified. One of the candidate egress ports is selected based on the traffic congestion information. The selection process is biased to prefer some candidate egress ports over others. Particularly, the candidate egress ports that provide non-minimal routes to the destination node and have high minimal route congestion metrics are disfavored by the selection process.
