本文针对城域宽带业务的应用和发展,分析了相关业务的承载需求和城域传送网络的融合演进趋势,提出了设计以数据内容为核心的城域光网络架构和建设统一的传送网络,并以T-MPLS技术作为融合网络的业务承载平台,满足全业务接入和网络扩展的需要。随着高速互联网接入(HSI)、以太网专线(EPL)、三重播放(TriplePlay)以及移动数据等宽带业务的发展,城域承载网络的带宽需求增长非常迅速,城域光网络对宽带业务的承载将随之而变。这些变化包括固定/移动网络融合、支持基于IP协议业务的网络转型、面向宽带业务的网络架构设计和网络技术选择。
In this paper, according to the application and development of metro broadband services, this paper analyzes the bearer requirements of related services and the evolving trend of convergence of metro transport networks. I propose to design a metro optical network architecture with data content as the core and build a unified transport network. T-MPLS technology as a converged network of business hosting platform to meet the full business access and network expansion needs. With the development of broadband services such as High Speed Internet Access (HSI), E-Line (EPL), Triple Play, and mobile data, the bandwidth demand of metropolitan area bearer networks has increased rapidly. As metro optical networks have become more and more important for broadband services The bearing will change accordingly. These changes include fixed / mobile network convergence, support for network transformation based on IP protocol services, network architecture design and network technology selection for broadband services.
