摘要
负载均衡在集群系统研究领域是一个比较重要的问题,它的八种调度算法是任务分配的核心,详细介绍了LVS中的调度理论,研究并讨论了常用算法的不足,在分析这些算法优缺点的基础上,提出了一种基于反馈的负载均衡算法理论,该算法引入一个负载容余参数可以更准确地描述集群节点的负载状态,在考虑各个服务节点处理能力真实负载的基础上,尽量简化负载均衡器的调度算法。经测试,其结果显示改进后的算法优于改进前的算法。
Load balancing in a cluster system of research is a more important issue, it is the eight scheduling algo- rithm is the core task assignment, detailing the LVS in scheduling theory, and discussed the lack of commonly used algo- rithms, In analyzing the advantages and disadvantages of these algorithms is proposed based on a load balancing algorithm based on feedback theory, the algorithm parameters to introduce a load capacity I can more accurately describe the load state of the cluster nodes, In considering each service node processing capabilities based on real load, try to simplify the load balancer scheduling algorithm. After testing, the results show the improved algorithm is better than before improve- ment algorithms.
