摘要
负载均衡在集群系统中的作用日益重要,而现有算法的效率不高、部署复杂的原因限制了其更进一步发展。通过分析不同类型的服务请求对服务器造成不同负载,结合监测服务器的CPU和内存利用的即时性能,在克服了现有负载均衡算法的一些缺陷基础上提出了一种简单稳定的基于服务分类和性能监测算法,并通过Web压力测试实验比较了该算法在实际应用中的均衡性能。结果验证了其在服务器集群系统有大的访问请求量时有突出性能,能够使集群系统达到良好的负载均衡。
The further development of load balancing is blocked by the low efficiency and high complexity of current algo rithms,although the importance of load balancing in Server Cluster is increasing day by day. After considering that different serve request makes different load to server and monitoring the instant performance of sever (using rate of CPU and memory), a simple load balancing algorithm which gets over disadvantages of the current algorithms is proposed based on services sort and capability surveillance. The algorithm's capability is excellence in the Web pressure test. It can make the Server Cluster load balancing usefully,especially when there is a large amount of request.
