System and method for providing a deadlock-free routing between switches in the fat tree topology

摘要

System and method is able to support the routing of packets between a plurality of switches in the middleware machine environment . Thus , the management traffic based on the Internet Protocol (IP), IP on InfiniBand in middleware machine environment (IP over Infiniband) (IPoIB) By enabling communication , which can be supported. A plurality of switches , using a routing algorithm , may perform routing for inter-switch traffic in the middleware machine environment . Then , by using the routing algorithm , the switch middleware machine environment , it can be selected as a hub switch for switching between the traffic can not reach the destination . In addition , when the route through the hub switch between the source and destination switches are present , it is possible to update the routing tables associated with the hub switch .
