高可用性集群中的动态负载平衡应用研究

Application Research of Dynamic Load Balance in HA Cluster

提出了一个基于性能预测的、计算连接权重的动态分配算法,以及网络调度器来实现高可用性集群中的动态负载平衡系统。该系统包括调度器、交互式会话支持单元等模块。测试表明,该系统能迅速、准确地找出最佳服务器来处理请求,在负载平衡的效能上有明显的提高,从而为接下来的服务等动作做好准备。

This paper proposes an opportunity dynamic assign algorithm that based on performance prediction scheduler, connecting weights, and dynamic load balance system, which utilizes the dispatcher. It includes severs sub system such as dispatcher, interactive session support unit etc. Experimental results show that the proposed algorithm can quickly and exactly find out the best server that deals with request and improve the performance on load balance. Thus it makes preparation for further service.
