入口链路负载均衡技术在Cisco设备中的应用研究

Research on the Application of Entrance Link Load Balance Technology on Cisco Device

简要阐述链路负载均衡的定义、类型和原理,主要研究入口链路负载均衡技术拥有在全球最先进的网络解决方案的供应商Cisco公司生产的专业设备上的应用,分析了Cisco入口链路负载均衡特性的架构、配置及实现的工作原理。Cisco的入口链路负载均衡技术通过在设备上的智能DNS解析功能,可以根据用户发起访问的源IP地址的不同,让用户通过不同的链路进行接入访问,实现对最优入口链路的选择,以达到使用户访问网站的响应速度得到提高的目的。

This paper briefly describes the definition, types and principles of link load balance technology, mainly studies the applica- tion of the technology on the professional equipment made by Cisco Company, which is the most advanced network solution provider in the world, and analyzes the architecture, configuration and working principles of Cisco entrance link load balance feature. By the intel- ligent DNS functions of the entrance link load-balancing technology on the device, it can make users access sites through different links and select the optimal entrance link according to the different source IP address of users, so as to improve the response speed of sites that users access.
