计算机集群中负载均衡技术的研究

Study of Load Balancing Technology in Computer Cluster

将多台计算机组织起来进行协同工作来模拟一台功能更强大的计算机来解决问题,这种技术称为集群技术。群集中负载均衡在多节点之间按照一定的策略(算法)分发网络或计算处理负载。负载均衡建立在现有网络结构之上,它提供了一种廉价有效的方法来扩展服务器带宽,增加吞吐量,提高数据处理能力,同时又可以避免单点故障。

The technology of organizing several computers together as one to solve the problems which need more powerful computer ability is called computer cluster technology. In the cluster, load balancing balances the load of network or computer according to certain strategy （arithmetic）. Based on the pop network structure, load balancing provides an efficient and low-cost way to broaden server band and improve the data processing ability of computer, and, at the same time, avoid single point mistakes.
