浙江大学软件学院论文 摘要 PAGE II 宁波联通DCN网络的设计与实现 摘 要 2009年初，原浙江联通和原浙江网通合并成为了新浙江联通，成立后的新联通面临着人员、办公场所、业务及支撑系统、管理流程的全面融合，而这些都是以IT网络的融合为基础。新联通成立后，为宁波联通建设新的DCN网提供了契机。DCN网，即综合数据通信网，各专业网管系统专用的数据通信网络。随着数据通信技术的发展，传统意义上的DCN网络正在逐渐演进成电信企业内部多应用的综合数据网络平台。为了实现一个物理承载网承载多个逻辑独立的业务，MSLP VPN等各项技术被引入到网络建设中。本文通过论述DCN网的特征和各项相关技术的原理，阐述了MSLP VPN等技术作为DCN网实现的核心技术的可行性，并通过对宁波联通融合后的网络现状及发展需求深入分析，构建出适合宁波联通的DCN网设计方案，并详细说明了最终实现的方案和步骤，最后本文总结了本次网络建设中的不足和对未来的展望。 关键词：DCN网络 BGP MPLS VPN 浙江大学硕士学位论文 Abstract Abstract In early 2009, the former Zhejiang Unicom and former China Netcom merger into new Zhejiang Unicom, China Unicom after the establishment faces many problems like human resource, office space, business and support systems, management processes, all need full integration, which are based on the integration of the IT network .The establishment of new China Unicom provides opportunity to build a new Ningbo DCN network. DCN network, Data Communication Network, professional network management system dedicated data communication network, with the development of data communications technology, traditional DCN network is gradually evolving into a telecommunications company platform within the multi-application for the integrated data network. In order to achieve a physical host multiple logical bearer network independent business, MSLP VPN technology has been introduced into the network construction. This article discusses the characteristics of DCN and MSLP VPN network technical principles, MSLP VPN technology can be used as the core of DCN network to provide technical feasibility, and through a network of Ningbo Unicom fusion-depth analysis of current situation and development requirement, build a suitable Ningbo Unicoms DCN network design, and details of the ultimate realization of the program .Finally, this article summarizes the la
