This invention discloses a method and apparatus for network traffic load balancing scheduling in a multi-node high-performance computing cluster, comprising three parts: network load detection, load estimation, and balancing decision. ArCa implements all parts on the host machine, requiring no modifications to the multi-node high-performance computing cluster network.
