基于混合策略的集群负载均衡算法研究

传统的负载均衡策略仅对某些类型的站点有效，而不能满足各种站点类型的要求。在分析已有方法的基础上，针对不同类型的用户请求特点，提出了一种基于混合策略的负载均衡算法。该算法通过对用户请求的分类调度来获得较高的cache命中率，同时还引入了会话保持技术和反馈环节来解决会话失效和负载不均衡的问题。实验结果表明，这种该算法能有效提高集群系统的整体性能。

Research on combined load balancing algorithm in cluster

Traditional strategi for all. Based on the existing es are just effective to some kinds of Web sites, but not suitable algorithms and the features of different kinds of users requests, a combined load balancing algorithm is proposed. requests, a higher cache hit rate is obtained. Fu By rth using different methods to dispatch users ermore, a session maintenance technology and feedback are brought in to solve the problem of session ineffectiveness and load imbalance. Experiment results show this algorithm can improve the performance of the cluster.
