摘要
自动交换光网络的出现是传送网概念的重大历史性突破,本文首先阐述这种新传送体制的基本概念和发展,然后介绍其控制面的功能要求,信令及相关接口,选路和信令网,控制面结构,网络性能要求等总体问题的规范和考虑,最后论述lP层与光传送层的融合以及两种基本网络演进结构的特点。
The occurrence of automatically switched optical network is the historic breakthrough for the concept of transport network. The paper described basic concept and development of this new transport network firstly and then introduced functional requirements of control plane, signaling and interfaces, routing and signaling network, architecture of control plane, network performance requirements, etc. Finally the paper discussed the convergence of IP layer and optical layer and characteristics of two evolution architectures.
