BGP/MPLS VPN配置管理系统的设计与实现

Design and Implement of Configuration Management for BGP/MPLS VPN

BGP/MPLS VPN是分布式企业网互联的有效解决方案。然而现有实际应用中,其配置管理较为复杂。提出了一种基于OOP(面向对象编程)技术的BGP/MPLS VPN配置管理系统设计与实现方案,通过NMS(网络管理系统)实现了对VPN及VPN站点等管理对象的有效管理。

BGP/MPLS VPN has lots of merits,such as flexibility in network configuration,expansibility and low operational cost compared to existed leased line of private network.In order to provide MPLS VPN efficiently,Network Management System(NMS) is able to collect information of many MPLS VPN-sites in the network,and manages the information of each node system and links in service provider network that supports MPLS VPN.In this paper,an MPLS VPN configuration management system that is designed and implemented by Object-Oriented Programming(OOP) is proposed.BGP/MPLS VPN Manager module in NMS with MOs is designed and implemented for VPN and VPN-site.Also,the MPLS VPN management system has CLI(Command Line Interface)-based auto-discovery function to collect information of previously configured MPLS VPNs.
