一种基于cookie会话保持的LVS集群系统

LVS cluster system based on cookie session maintenance

针对基于源IP会话保持的IPVS在高速代理上网环境中存在的会话失效和负载不均衡问题,研究了LVS系统的设计原理与实现方法,并结合Web应用中cookie会话保持机制,提出了基于cookie会话保持的改进方案。实验结果表明,改进的基于cookie会话保持的IPVS负载均衡集群系统能有效地解决高速代理上网环境中存在的会话失效和负载不均衡的问题,同时在相同的并发用户量的情况下响应时间更短、吞吐率更高,特别是在高并发情况下集群性能更优。

Aiming at the session failure and load imbalance problem of IPVS based on the source IP session maintenance in the high-speed proxy environment, this paper studied LVS design principle and implementation. And combined the cookie session maintenance mechanisms on Web applications, it proposed the improvement scheme based on the cookie session maintenance. Experiments show that the improved IPVS load balancing cluster system based on cookie session maintenance can effectively solve the problem of session lost effectiveness and load imbalance in the high-speed proxy environment, and the performance on both transaction response time and throughput is better under the same concurrent users, especially has better performance under high concurrency.
