Internet大事记

Development of Internet VPN

虚拟专用网与Ｉｎｔｅｒｎｅｔ的结合形成了当前业界发展的一个热点－ＩＮＰＶ。ＩＶＰＮ通过加密、鉴定和隧道协议来实现，它把路由器交换机和传输线结合在一起，以实现安全保密的通信。ＩＥＴＦ的ＩＰｓｅｃ是隧道协议的一种，为ＶＰＮ之间的互操作提供了标准，目前已有一些ＩＰＳ提供了具有一定安全性的ＩＶＰＮ业务。

The combination of VPN with Internet results in IVPN.IVPN is implemented with encryption, authentication and tunneling protocols.It enables secure communications by integrating routers, switches and transmission lines.IETF IPsec is one of the tunneling protocols, providing VPN-to-VPN interoperability.At present, some ISPs have alrendy provided IVPN services with certain degree of security.
