广东省广电集团广域主干网和广州供电分公司城域网虚拟专网互联分析与测试

Analysis and testing of VPN interconnection between GPG backbone WAN and MAN of Guangzhou Power Supply Branch

分析了采用异步传送模式 (ATM)技术的广东省广电集团广域主干网络和采用吉位以太网技术的广州供电分公司城域网的虚拟专网 (VPN)方法原理 ,并对两者之间VPN互联的可能性进行了探讨。介绍了VPN互联的测试方法和结果。最后指出 ,目前两者的VPN互联宜采用ATMVC +RFC14 83routing封装方式。

The backbone WAN (wide area network) of Guangdong GuangDian Power Grid Group Co.,Ltd.is based on asynchronous transfer mode (ATM),while the MAN (metropolitan area network) of Guangzhou Power Supply Branch on gigabit Ethernet.This paper analyzes the realization means and principles of virtual private networks (VPNs) of the two,and gives several possible methods for interconnecting these VPNs.The testing method for VPN interconnection and the results are provided,and the packaging of ATM VC+RFC1483 routing is suggested for the VPN interconnection at present.
