摘要
针对单纯提高硬件性能已经无法解决的网络服务质量问题,提出一种基于Linux集群技术的负载均衡分配方法。在Linux虚拟服务器异构集群的基础上,引入动态反馈模型来优化采集负载信息的通信机制,并通过智能分配策略来避免传统轮询算法对服务器资源的过度消耗。结合Linux脚本及命令进行性能测试,实验结果表明,提出的智能分配方法比加权轮询算法具有更好的响应时间和吞吐量。
The rapid increase of concurrent request brings great burden on the server.Simply raising the performance of hardware cannot fundamentally solve the problem and on the contrary it will increase overhead cost.Therefore load balancing is becoming one of hot research topics.The proposed method in this paper is based on the LVS heterogeneous cluster.It adopts dynamic feedback mechanism to optimize the communication mechanisms of load information collection, and gives an intelligent allocation method to improve the overall system performance.The experiment results show that the proposed method can significantly improve throughput and decrease response time compared with the weighted round robin algorithm.
