摘要
网络集群环境下的负载均衡优化问题是一个各种软、硬件参数优化整合的结果。首先针对加权轮询算法和加权最少连接数算法的实现原理进行分析,得出两种典型算法的不足。再提出一种基于自适应权值的负载均衡算法。并利用OP-NET软件对上述3种算法进行仿真对比,证明新算法在CPU的利用率、服务器负载、服务延迟等方面都优于已有算法。
In web cluster environment, the problem of load balancing is a result of optimized integration of soft- ware and hardware. Firstly, the algorithm of Wighted Round Robin and Weighted Least-Connection are analyzed, then it finds the shortage of the two algrithom. An algorithm of Load Balancing Based on self-Adaptive Weight is proposed. They are compared by using software 0PNET to simulate. It is proved that the proposed algorithm is prior to exsiting algorithms in cpu utilization, ：server loaded and service delay.
