利用LVS中的IP负载均衡技术建立可伸缩性网络服务

Establishing the Expandability Network Service Using IP load Equalization Technology in the Science of LVS

从LVS的通用体系结构入手,分析了IPVS软件的工作原理,讨论了三种IP负载均衡技术;在分析网络地址转换方法(VS/NAT)的缺点和网络服务的非对称性的基础上,给出了通过IP隧道实现虚拟服务器的方法VS/TUN,和通过直接路由实现虚拟服务器的方法VS/DR,极大地提高了系统的可伸缩性。该技术为建立和维护大型网络服务具有实际应用价值和指导意义。

Based on the analysis of the IPVS software the discussion of the three kinds of IP load equalization technology is obtained from the LVS general system architecture. Based on analyzing the shortcoming of method of network address translation （VS/NAT） and the asymmetrical of network service, it has come up the realization hypothesized server method VS/TUN via the IP tunnel and the direct routing realization hypothesized server method VS/DR, these outcomes have greatly enhance the system expansion flexibility. This technology has the practical application and knowledge values and it is suitable for setting up an establishment for maintenance of the large-scale network service.
