基于软路由的IP虚拟网研究

IP virtual network based on soft-route

企业在不同地域或空间的分部通常对于企业的内部网络有一定的网络可靠性、结点移动性以及通信及时性的要求。目前的解决方案有专用网、虚拟专用网(VPN)和NTA等技术。但VPN以及NTA所做的都是基于某种中心服务器来构筑整个企业网的。文中所提出IP虚拟网是在对等的分支机构之间通过软路由机制来实现,这是从另一个角度来解决数据集中所导致的安全问题。

In the enterprises there are requirements of the network-reliability, the node-mobility and the correspondence-prompt on the different branches. The current solutions are private network, virtual private network （VPN） NTA and so on. But the VPN and NTA are based on some kinds of central server to construct the whole enterprises network. The IP virtual network is realized through the soft-route among the peer branch office and settles the secu- rity problem due to the data concentration.
