电信行业智能DNS实现负载均衡

Implementation of Intelligent DNS Load Balancing in Telecommunications Industry

目前互联网飞速发展,单服务器的架构已无法满足急速增长的应用负载要求,而常用的负载均衡设备存在很多问题和缺陷,在流量激增与DDOS攻击中成为了新的网络瓶颈,这经常导致服务器无法正常地响应。所以针对以上情况推荐通过对传统DNS负载均衡进行功能扩展使用动态智能DNS来做负载均衡,其优点是克服了传统DNS无法智能判断服务器状态的缺陷,从而可以达到各种昂贵DNS设备类似的功能,并且由于无需链路中增加多余的节点,从而避免了多余的瓶颈与故障点出现。本文表述了智能DNS负载均衡技术的原理、优点、以及实现负载均衡所涉及的关键技术。

Currently,internet is developing rapidly,the single server has been unable to deal with rapidly growing application request,but the commonly used load balance equipment exist constitutive flaws which often can become the new network bottleneck when the current capacity enhance or DDOS attacks,this often leads to server cannot normally response.Therefore,we recommend to use dynamic intelligent DNS to carry on function expansion to make load balance.The dynamic intelligent DNS optimize the traditional DNS by being unable to do the intelligent judgment server condition,and might achieve each kind of expensive DNS equipment similar function.Because it did not need link to unnecessary node,intelligent DNS load balance avoids the bottleneck and the fault point appearance.This article has indicated the key principle,the merit of the intelligent DNS load balance technology,as well as key technologies load balance realization involves.
