摘　　要：根据当前网络发展趋势和大客户组网的业务需求,首先,分析MPLSVPN技术较传统ATM/SDH组网的优势;其次,介绍运营商应用MPLSVPN技术承载大客户组网业务,同时结合QoS、链路保护技术提高业务质量和可靠性的各种具体方案。主要方案有单一MPLSVPN和多种MPLSVPN技术组合应用两类。单一MPLSVPN又分为三层MPLSVPN(BGP/MPLSVPN)和二层MPLSVPN(VLL,VPLS);多种MPLSVPN技术组合应用又可分为BGP/MPLSVPN终结VLL,VPLS终结VLL和VLL与VLL对接。通过实验室的测试,验证了以上方案的可行性和承载效果,给出了采用不同的MPLSVPN方式承载大客户组网业务的应用场景。Firstly, based on current trends in network development and networking needs of major clients, the advantages of MPLS VPN technology over traditional ATM/SDH are analyzed. Secondly, the paper puts forward several schemes that the ISP provides networking service to major clients in IP network with MPLS VPN and uses QoS, link protection technology to improve quality and reliability of the service. There are 2 kinds of schemes： single MPLS VPN and mixed MPLS VPN. A single MPLS VPN is divided into three layers of MPLS VPN （ BGP/MPLS VPN） and two layers of MPLS VPN （ VLL, VPLS）, mixed MPLS VPN can be divided into BGP/MPLS VPN end VLL, VPLS VLL and VLL and VLL butt end. And then, the paper verifies itg feasibility through laboratory tests. At last, it gives the applicative conditions of carrying networking services of major clients by using MPLS VPN technology.
