摘　　要：企业网络从企业本部出局到城A和城B两座城市,仅有单独的一条光缆专线,缺少备份线路,因此不具备容灾容错的功能。利用基于MPLS的VPN技术,在公网的基础上,建立起一条虚拟通道连接本部与远端来备份现有专线,既节约了建设费用,又减少了维护费用。MPLSVPN具有扩展性强、安全可靠以及与QoS兼容良好等特点,可以提供安全、可靠的连接为公司综合信息网服务。The enterprise’s information network from the departure of the enterprise’s headquarters to two cities, city A and the city B, has only one dedicated optical cable line and lacks backup lines, so it does not have the function of disaster tolerance and fault tolerance. Based on the MPLS-based VPN technology, a virtual channel is established on the public network, so as to connect the headquarters and the remote end and back up the existing leased line, which could save construction costs and reduce maintenance costs. MPLS VPN has the characteristics of strong scalability, security and reliability, and good compatibility with QoS, and can provide secure and reliable connectivity for the company’s integrated information network services.
