基于Agent的Web缓存主动负载均衡模型

Active load balance of Web caching server model based on agent

为改善Web缓存系统中存在负载不平衡现象,提出了一种基于Agent的自主式缓存负载平衡方案.文中对Agent的结构进行了设计,指出了现有均衡算法的不足,提出了基于主机检测的动态复制均衡算法和交换负载均衡算法.最后通过仿真对方案的有效性进行了检验,检验结果表明,选择不同的均衡策略和算法与传统方法相比有更好的灵活性.

An active load balancing scheme which based on multi-agent has been proposed to improve th load inbalancing in Web caching system. The structure of agent are designed; and the deficiency of pres ent balancing algorithm is pointed out; and a dynamic duplicate load balancing algorithm with hoet statu and an object changing load balancing algorithm are presented. At last, the validity of scheme is examined by emulator. The results indicate that compared to the traditional algorithm, choosing different hal ancing algorithm has better flexibility.
