摘要
随着网络的迅速发展,服务器集群技术得到了广泛的应用,对负载均衡策略的研究也变得越来越必要,但当前的分布式负载均衡策略始终存在性能和开销不能兼顾的问题。本文将软件抗衰思想引入负载均衡策略设计,根据系统内的均衡程度来确定均衡过程的起止时机,在一定程度上解决了这一矛盾。文内给出了相应的实现算法。
With the rapid development of network, the technique of server clusters is widely used. Accordingly the research on load balancing techniques becomes more and more important and necessary. But at present there always exists the conflict between cost and performance in distributed load balancing strategies. This paper introduces the idea of software rejuvenation in the design of load balancing strategy. According to the degree of balancing in the whole system, the new strategy decides when and which machine in the cluster runs the balancing process. It partly resolves the conflict , there after, the relevant algorithm has been shown.
