虚拟技术在现代通信网络中的应用与研究

针对现代通信网IP化、虚拟化发展特点和业务需求，为了满足不同业务的不同QoS要求，将虚拟技术应用于PSTN、IP网和增值业务平台，提出移动通信业务支撑网MPLSVPN应用方案，它采用L3MPLSVPN技术在CE设备上划分与MIS、BOSS、OA业务系统对应的3个VLAN来实现隔离和互访，在一个物理网络上实现统一平台管理。结果表明：虚拟技术可以灵活构建电信级VPN，在现代通信网以及NGN中有很好的应用前景。

Application of Virtual Technology in Modern Communication Network

Aiming at the development of IP network and virtualization, and different QoS demands, the virtual technology is applied in PSTN, IP network and value added service platform. This paper puts forward a MPLS VPN application scheme for the business supporting network of the mobile communication. It uses the L3 MPLS VPN technology to divide the 3 VLANs corresponding to MIS, BOSS and 0A service systems on CE equipment, and thus realizes isolation and mutual access, including unified platform management in one physical network. The result shows that the virtual technology can flexibly construct telecom-level VPN, and has good application prospects in modern communication network and NGN.
