高速访问多出口局域网对外资源的方法研究

Research on Method of Accessing Resources of Multi-homed LAN with High Speed

随着Internet在教学上的广泛应用,校内外用户对校园网的要求越来越高,很多校园网除连接教育网外还与本地ISP开通多个出口,以解决网速与应用服务访问的瓶颈问题,在这种环境下DNS的安全与运行策略是保证网络稳定运行、有效解决瓶颈的关键.文章提出了一种基于多出口环境下运用bind9、PBR与NAT技术实现高速访问多出口局域网对外资源的有效方法.

The users make strict demands on campus networks with the wide use of Internet on teaching.Except CERNET,many campus networks join Internet through multiple other local ISP to solve the bottle-neck of different networks,and in this case the security and operational policy of DNS is the key of solving the bottle-neck and ensuring the steady run of campus networks.The paper provides a kind of method of accessing resources of multi-homed LAN with high speed using bind9 combined with PBR and NAT.
