Research on load balance mechanism in WS-HLA

With the expansion of parallel access in WS-HLA system, it has become one of the most important problems in WS-HLA that how to implement the load balance, ensure the processing capacity and service quality. A load balance mechanism based on the feedback control of load is proposed in this paper, which uses the transparent mechanism of WS-HLA bus layer, and designs the load balance models and monitor models in web services that provides efficient management and configuration function for various redundant services. The load balance mechanism supports the load balance strategy and load measurement method for custom application according to a flexible double-load-balance framework, gives a significantly efficient support for high performance, high scalability and high availability in WS-HLA.
