SYSTEM AND METHOD FOR USING VIRTUAL LANES TO ALLEVIATE CONGESTION IN A FAT-TREE TOPOLOGY

摘要

A system and method can alleviate congestion in a middleware machine environment with a plurality of switches in a fat-tree topology. The middleware machine environment can support a plurality of end nodes and allows for generating a virtual lane assignment for every pair of source end node and destination end node. Then, the packet flows from a source end node to different destination end nodes sharing a physical link can be distributed across different virtual lanes in order to avoid the head-of-line (HOL) blocking.
