应用服务器的负载平衡技术和实现方案

Technology and Implementation Scheme of Load Balancing for Application Server

在下一代网络中,应用服务器通常基于分布式计算技术构建,负载平衡是它的重要性能指标之一。本文采用集中式算法实现应用服务器的负载平衡,重点讨论了两种负载分配模型和几种消息定位策略;此外还给出一个通用的负载平衡实现方案,CORBA技术是实现该方案的一种很好选择。

In t he next generation network(NGN),application server(AS)is constructed based on di stributed computing technologies,thus load balancing becomes one of the most imp ortant performance measures.In this paper,the centralized algorithm is proposed to gain load balancing of AS.The emphasis of our discussion is laid on the two l oad distribution models and several message location policies.In addi-tion,this paper presents a universal implementation scheme for load balancing of AS.CORBA technology is a good choice to implement the scheme.
