摘要
大规模的组建VPN网络已经成为一种趋势,越来越多地受到用户的广泛关注。从总体来说,VPN技术非常复杂,它涉及到通信技术、密码技术和现代认证技术,是一项交叉科学。隧道技术对于构建VPN来说,是一个关键性技术。它在源局域网与公网的接口处,将数据作为负载封装在一种可以在公网上传输的数据格式中,在目的局域网与公网的接口处将数据解封装,取出负载。从隧道技术的发展,对各种隧道技术做了一个简单的分析,了解VPN组网的安全技术。
Setting- up large- scale VPN network becomes an important task,VPN has been attracted extensibe attention of business subscribers. In one speak, VPN technology is very complicated, it involves in communication technology,cryptography,authentication technology,it is an interdisciplinary. Tunnel technology is a key technology to set- up VPN network. In the port of host LAN and Intemet, the data is packed in a pattern that can transport in Intemet, in object LAN, the data is decompression and can use it. Give a simple analysis of the tunnel technique from the development of tunnel technique, to know the security technical of the setting- up large- scale VPN.
