TCP/IP网络自治系统内部边界路由技术研究

Study on Border Routing in Autonomous System of TCP/IP Network

因特网是如今最典型的ＴＣＰ／ＩＰ网络应用。因特网将网络分成许多自治系统。选择ＯＳＰＦ作为内部网关协议的自治系统，又将自治系统分成若干区域，这样，路由信息的交换就可以在不同的层次进行，用于交换路由信息的数据报大大减少，节省了更多的网络带宽以传输最终的数据。文中对自治系统的内部结构进行了研究，并主要讨论了自治系统内部、区域间交换路由信息的技术。

The most typical application of TCP/IP technologyis Internet. Nowadays,Internet is divided into many Autonomous Systems (ASs) . If an AS choose OSPFas its interior gateway protocol, some areas may be introduced into it. Then ,exchange of routing information will occur at different levels. A group of networks are condensed into a single route leaving more network spacefor non - route datato be transferred .The main purpose ofthisarticleistoshow the architecture in ASs and how they handle the routing problems among areas.
