一种基于服务类型的Web集群负载均衡算法

Web Cluster Load Balancing Algorithm Based on Service Type

在电信增值业务系统开发中,大量的用户和多样的服务使得服务器集群的负载均衡问题显得日益突出,是电信业务系统开发成功与否的一个关键问题。通过对影响服务器负载关键因素的分析,提出了一种新的基于服务类型的负载均衡算法,引入了负载信息纠偏因子来周期性地纠正服务器负载信息的误差。通过解析请求的服务类型,按计算的概率转发请求到合适的服务器上。

During telecom value-added service development process, load-balancing problem on server cluster is becoming more and more serious due to a mass of users and various services. This is a crucial problem on successful developing telecom value-added service system. Based on crucial factor of server cluster load balancing analysis, a new algorithm based on service type is proposed, bringing in load information correction factor to correct load information difference periodic. Through analyzing service type of the request, request is forwarded to suitable server according to the computed probability.
