SYSTEM AND METHOD FOR ROUTING TRAFFIC BETWEEN DISTINCT INFINIBAND SUBNETS BASED ON FAT TREE ROUTING

摘要

A system and method can rout traffic between distinct subnets in a network environment. A router that connects the distinct subnets such as InfiniBand (IB) subnets can receive a list of destinations that the router is responsible for routing one or more packets to. Furthermore the router can obtain information from one or more switches in the at least one subnet on which downward output ports of the router can be used for routing the one or more packets and build a routing table based on the obtained information.
