The Design And Implementation Of Resources Synchronization And Web Guis Of VPN Network Management System

With the development of the technology of MPLS VPN, many companies selected MPLS VPN as their primary project when constructing their private enterprise network and now MPLS VPN has been one of the new services which telecommunication operators actively develop. In order to be in a good situation, on one side telecommunication operators kept to provide new services, on the other, they converted their competition content from simple low level's price competition to high level service competition which treated the quality of services as the core competition capability of an enterprise. So the MPLS VPN network management system based on service level will help the telecommunication operators to improve their competition.J2EE is a Java component-based specification for enterprise application system development which defines a multi-tier platform of enterprise information system. The advantages of J2EE such as multi-tier architecture, extensibility, cross-platform, flexibility and maintainability make it be primary choice when developing enterprise information system, which can simplify and specify the development and deployment of the enterprise application system.The paper was deriving from the project VPN network management system, which I engaged into develop. The system used J2EE architecture and was accomplished through the cooperation of ZZnode company and zhong-ying company. The two companies firstly developed their own modules respectively, then, the modules were integrated together. The systems of two companies maintained their own database respectively, so some resources needed to be transmitted. I took charge of the design and implementation of resources synchronization and some web GUIs.
