基于双层分配器的Web服务集群负载平衡解决方案

Double-dispatcher-based load balancing solution on Web service cluster

为了解决目前W eb服务集群存在的问题,提出了一个双层分配器负载平衡模型。在确定了负载指标的基础上,给出了该模型的负载平衡算法。并就服务器迅速过载问题和容错性问题提出了初步的解决方案。最后,对模型的性能进行了测试,结果表明模型达到了较好的负载平衡。

A double-dispatcher-based load balancing model of Web service duster was given. The purpose was to solve the problems existing in the current web service cluster. One was that the load index was not desirable enough; the other was that documents distribution was not accurate enough. After making sure of the load index, the load balancing algorithm for the model was put forward. In addition, the preliminary scheme on the servers＇ instant over loading and fault tolerance was presented. At last, a test on the performance of the model shows that the model has better load balancing.
