动态DNS实现智能负载均衡

随着目前网络应用迅速发展,单服务器结构已无法应付急速增长负载要求,而常用的负载均衡设备存在结构性缺陷,即往往会在流量激增或遭DDOS攻击时成为新的网络瓶颈。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节点,避免瓶颈与故障点出现。本文表述了动态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。

Dynamic DNS Intelligent Load Balancing

With the present network application rapid development, the single server structure has been unable to deal with rapidly growing application request. but the commonly used load balance equipment existence constitutive flaw-it often can become the new network bottleneck when the current capacity under huge enhance or suffer form the DDOS attack. Therefore, we recommend use dynamic DNS (DNS to carries on function expansion) to make the through load balance in view of above situation. The dynamic 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, dynamic DNS load balance avoids the bottleneck and the fault point appearance. This article has indicated the key technologies which the dynamic DNS load balance technology principle, the merit, as well as realization load balance involves.
