【摘要】 基于四川联通宽带综合接入网工程建设的实际需求，作者研究了大型网络规划设计的技术与方法，深入探讨了VPN系统结构、实现技术与方案，探索了如何应用MPLS VPN技术满足运营商为其用户提供VPN业务的需求。 针对城域网上部分设备不支持MPLS的问题，作者提出了综合使用VLAN与MPLS技术实现全网VPN业务的方案，以及利用VLAN—MPLS VPN—VLAN的结构实现端到端的VPN业务的技术和方法。 作者还探讨了基于IP城域网的网络，如何保证VPN用户的数据传输安全和网络服务质量等课题，并给出了相应的解决方法和相应思路。 在理论和技术研究的基础上，作者实际参加了四川联通宽带综合接入网工程建设，完成了网络总体规划设计、网络路由协议的选择和实现、VPN网络的设计与实现工作。更多还原

【Abstract】 Based on the practical needs in construction of Sichuan Unicom network, the authormade a deep research work on the technology of big-scale network, the VPN structure,design and realization solutions, as well as how to satisfy the operator’s the VPNservice need with MPLS VPN technology.For some equipment in the regional network being incompatible to MPLS, the authorworks out a comprehensive design by adopting both VLAN and MPLS to realize VPNservices, which also includes the use of VLAN-MPLS VPN-VLAN structure inend-to-end VPN service.Moreover, the author probes into the field of IP MAN network and discusses thequestions like how to guarantee the VPN users’ data transferring security and networkservice, all of which are provided with possible solutions accordingly.Beyond the theoretical and technological research, the author took part in SichuanUnicorn’s IP Broad-band Comprehensive Network construction. He successfullydesigned the general layout of network, worked out the application of the routingprotocol, and realized VPN network design and implementation.更多还原
