| Abstract: | A double-dispatcher-based load balancing model of Web service cluster 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. |
