The Research Of Load Balancing Of Web Cluster Severs

With the development of the computer and Internet, the demand of service of web severs become more and more, the load balancing cluster is widely used in web servers for its low price and higher ability and scalability. So people are more and more interested in how to raise the integrated processing ability of the cluster sever.The strategy of the load balancing is the critical of raising the function, the purpose of it is to distribute the assignment to the real node of the cluster depend on the ability of the processors, for that this can raise the ability and quality of service. The design of the load balancing strategy will affect the cluster function directly. Dynamic feedback can adjust the proportion of the server based on node's load status, in order to avoid accepting more request when overloading, so that this can raise the processing ability of the cluster.This paper discusses the conception and characteristic of cluster, and analyzes the technology of cluster which in common use. And focus of researching the principle and Characteristic of cluster, and research the technology and algorithm in detail. And then analyze the advantage and disadvantage of the algorithm. Then design a new strategy with the dynamic feedback principle. And setup the simulate environment and test the method. In the end, the experiment shows that this algorithm can raise the quality of service and decrease the delay time of cluster effectively.
