Implementation of Expanding and Achieving High-reliability Network Based on DNS

本文阐述了接入双ISP的校园网络,在无法使用动态路由的情况,利用DNS技术实现网络的扩展和高可靠性的解决方案。它综合了BIND的Forwarder、MX记录、Round Robin、View等关键技术,合理利用双ISP的带宽资源,从而达到提高网络速度、提高网络稳定性的目的。

This paper mainly introduces the solution for implementation of expanding and achieving high-reliability network based on DNS, in the case that dynamic routing can not work on the campus network that access internet through dual ISP. It combines the Forwarder, MX Record, Round Robin, View and other key technologies of BIND, it rationally using dual-ISP bandwidth and increasing network access speed to improve the stability of the campus network.
