Improvement on LVS based IP network connection status synchronization

Abstract

In typical IP network, load balancing is adopt to enable the load of all servers approach a global optimal balanced by dynamically dispatching new flows to different servers in the network. Linux Virtual Server (LVS) plays an important role in the dispatching process. However, previous LVS-based researches have failed to consider expansibility, efficiency and security. Based on this, we proposed a novel method focusing on LVS connection state synchronization in this work and extend the traditional method by adopting a novel network topology structure and a series of corresponding strategy.
