本文通过广东省科学院内部网络Internet接入扩容的实例,讨论了IP隧道技术和最短路径优先协议(OSPF)的具体应用,提出了一种在保持原网络出口结构情况下,采用IP隧道技术租用新的线路建立虚拟网络通道来实现扩容的方法。扩容对于用户的应用是透明的。
This paper discusses the concrete application of IP tunneling technology and shortest path first protocol (OSPF) through the example of Internet access expansion in the internal network of Guangdong Academy of Sciences. In this paper, we propose an IP tunneling technology to lease new Line to establish a virtual network channel to achieve the expansion of the method. Expansion of the user’s application is transparent.
