浅谈BGP/MPLS VPN技术的实现

Analysis on planning and implementation of BGP/MPLS VPN networking

伴随着信息化浪潮在全球的兴起,世界上有越来越多的企业开始在互联网上销售产品和服务。这样做不仅为企业节约了成本,也创造了价值,甚至有企业利用互联网将远在异地的分支机构与自己的总部互连起来,实现了利益最大化。早期应用于这方面的技术主要是虚拟专用网但最终由于其部署和维护成本过高而导致一般企业难以承受,于是人们开发出了MPLS VPN技术,该技术使得企业部署和维护VPN的成本大大降低,因此受到越来越多的中小企业青睐。文章探讨了BGP和MPLS VPN的相关技术,对中小企业具有一定的参考意义。

Along with the wave of informatization all around the globe, an increasing number of enterprises worldwide have begun to market their products and services on the Internet, which not only saves costs but also creates value. Even there are enterprises that utilize the Internet to make an interconnection between the remote branches at other locations and their own headquarters, in order to realize profit maximization. Early technologies applied in this aspect mainly included virtual private network, though it finally went beyond the affordability of general enterprises because of its over-high costs on deployment and maintenance. As aresult, people developed a kind of MPLS-based VPN technology, which has significantly lowered the enterprises＇ costs on deployment and maintenance of VPN and therefore enjoys an increasing favor by small- and medium-sized enterprises. This paper focused on studying BGP protocol and MPLS- based VPN technology, which was of certain reference value.
