基于域名解析的多链路负载均衡技术应用

李俊锋


相对于多条专线接入的传统方案,本文方案从两个不同运营商各接入一条链路,利用基于域名解析链路负载均衡技术对医院的移动支付服务网络访问分流,以增加链路带宽的使用率,减少跨运营商访问造成的额外延时。同时,通过灵活配置域名解析策略,可以在一条链路断开时,及时将域名解析到另一条链路的公网地址上,从而能够提供链路备份功能。区别于策略路由的实现方式,该方案通过减少域名解析服务器生效时间,加快链路切换速度,减少网络链路中断对医院移动支付业务的影响。

Application of Multilink Load Balancing (MSLB) Technology Based on Domain Name Resolution

LIU Yang, LU Xi, LI Junfeng

Abstract Compared with the traditional scheme of multiple separated line access, this paper has introduced a solution that accesses one link from two different operators, and uses domain name resolution of link load balancing technology to divert the access of mobile payment service network in hospital, in order to increase the use rate of link bandwidth and reduce the extra delay caused by inter operator access. At the same time, by flexibly configuring the domain name resolution strategy, the domain name can be resolved to the public network address of another link in time when a link is disconnected, so that the link backup function can be provided. Differ from the implementation of policy routing, the scheme speeds up the link switching speed by reducing the time of the domain name resolution server and reduces the impact of network link interruption on the hospital mobile payment service.
