综合业务平台负载均衡的研究

Research of Load Balancing for Integrated Service Platform

为满足下一代网络中综合业务平台(ISP)运行的稳定性、高可靠性及实时性要求,针对业务特点,设计了能达到负载均衡目标的定制接受算法.根据业务量差异情况设置参数,此算法可以较快地响应业务量变化,调整权值到最佳状态.仿真实验表明,应用该算法分发业务请求可以降低处理的平均响应时间.此外,采用多级Java管理扩展(JMX)结构实现了平台多服务器负载均衡机制,从而根据业务量情况灵活的增删服务器个数,实现对平台中多台服务器的分布式管理.

In order to ensure integrated service platform(ISP) to be stable,reliable and real-time,the load balancing of ISP is researched and then a new load balancing algorithm customized algorithm(CA) is proposed.By setting different parameters according to workloads of telecomm value-added services,the algorithm can respond to the variety of services workload and adjust server's receiving weight values rapidly.The experimental results indicate that CA allows ISP to reduce the services' average response time.Furthermore,the load balancing mechanism is implemented on the based of multi-level Java management extension(JMX) architecture,which realizes distributed management and allows servers to be added or removed on line flexibly.
