WEB服务器集群系统中负载平衡的设计与实现

-With the increase of users and dense tasks in Internet and Intranet, the transacting capability

of the single Web server is limited, which has already become the new bottleneck of network visiting. If

the Web server cluster is equipped with the features of high availability and load balancing, it becomes

the best solution for the preceding problem. This paper attaches importance to the principle and the im-

plementation technology of load balancing in the Web server cluster system. The performance of the

Web server cluster system is analyzed with the queue theory, and dynamic load balancing is implemented

with real-time collecting performance data of the Web servers and periodical judging of light loading Web

servers. Experimental results show that the throughput of the Web server cluster system is increased by

30　with the load balancing method.
