MPLS VPN Services Automated Deployment System Design And Implement

In data network region, IP technology is evolving. Because of its big difficulty, inferiority routing, and inefficiencies , ATM, as the former broadband communication network and innovation, is faced with very large challenge that how to bring ATM technology in harmony with IP technology, that how to combine router and switch in order to provide new services and keep the present invest at the same time. MPLS solves the above problems. MPLS is the next generation wide area network technology after IP technology. It is one of the technologies those have the best development prospect in market. The great potential advantage for operation supporter is that MPLS provides VPN.In the paper, the author studies that how to make MPLS VPN services automated deploy in existence network only by one client. That would provide operation supporters with a series of solutions of services deploy and management, according with operation system, and help operation supporters to improve theirs services quality and services competition ability. In order to deploy MPLS VPN service, I solve two problems in this paper:1. From the true network, abstracting VPN resource model that is easy to manage and fit for software development,2. Implement the process from the client, middle service, to device, in order to deploy service only by one client.For this system's architecture, we select the industrial standard: J2EE. The modularized design and flexible adapter pattern make the system have the favorable expansibility for service capacity and service type, for network, network element and EMS interface, as well as for external interconnect interface based on OSS model.The author gives the detail represent, including resource modeling, service deploying, network adapter and putting in practice by the development process of telecom VPN system. The product gets a good estimate.
