| 摘 要： | 负载均衡是集群系统研究的一个重要问题,负载均衡算法是集群任务分配的核心,介绍了LVS中的负载均衡算法,讨论了常用算法的不足,在分析这些算法各自优缺点的基础上,提出了一种改进的基于反馈的负载均衡算法,算法引入一个负载容余参数以更准确地描述集群节点的负载状况,在考虑服务节点真实负载,处理能力的基础上,尽量简化负载均衡器的任务分配算法.测试结果显示该算法优于静态算法.

| Abstract: | Load balance is an important problem of cluster. Thg core of task distribution is the load balance algorithm. LVS load balance technology is introduced briefly, the known load balancing, algorithms and their merits and demerits are discussed; And then, according to these defects, a improved load-balancing algorithm is presented based on feed_back. A remained_capacity is brought in to describe the load state of cluster node more accurately to balance the load more optimization considering the real load and capability of server. Test results proved that this improved dynamic load balancing algorithm is more effective than static algorithm. |
