Anycast架构下的铁路DNS系统解决方案

近几年铁路信息化的飞速发展,已经成为铁路现代化的一个标志,作为信息化重要组成部分的DNS系统,为所有对内对外的信息系统提供地址解析服务,因此其可靠性、安全性至关重要,利用Anycast架构建设的DNS系统可以有效解决铁路DNS系统存在的性能瓶颈,以及难以抵御网络攻击等问题,可以极大提升铁路信息系统的可靠性、安全性。

Solution of Railway DNS System Over Anycast Framework

The development of railway information systems has become a symbol of railway modernization. As an important part of railway information systems, Domain Name System provided address resolu- tion service for all internal and external information systems. Therefore, the reliability and security of DNS is extremely important. The DNS established over Anycast framework can solve performance bottleneck effectively and enhance the defense capability of Railway DNS against network attacks. As a result, the reliability and security of railway information systems can be promoted substantially.
