主要介绍了在移动通信网、固网融合的前提下,对行业应用VPN虚拟网组网模式进行了探索、创新。通过在3G移动分组网、宽带VPN网间部署跨域的MPLS VPN(采用MPLS技术在骨干的宽带IP网络上构建企业IP专网)的方式,实现了企业内网与3G移动分组网的互通。同时采用了多种措施保障VPN虚拟网的组网安全,并实现了行业应用用户地址复用问题,为行业应用的发展,开辟了新的组网模式,并提供了有力的支撑。
Mainly introduced in the mobile communication network, fixed network convergence under the premise of the application of VPN virtual network industry networking model for exploration and innovation. By inter-domain MPLS VPN deployed in the 3G mobile network and broadband VPN network (using MPLS technology to build an enterprise IP private network on the backbone broadband IP network), interworking between intranet and 3G mobile network is realized. At the same time, a variety of measures have been taken to ensure the network security of the VPN virtual network and the reuse of industrial application users’ addresses has been solved. This has opened up a new networking mode and provided strong support for the development of industry applications.
