Abstract

A system and method can prevent traffic congestion in a middleware machine environment with a plurality of switches in a fat-tree topology. A subnet manager can sweep a subnet in the middleware machine environment to discover changes and maintain the subnet fully connected. A performance manager can retrieve performance and error-related information from one or more performance management agents that are associated with one or more components in the subnet. Then, a host can dynamically reconfigure one or more virtual lanes in order to improve network performances.
