主要介绍基于GMPLS的多区域/多层面网络的基本概念与功能需求,并对功能需求分成两个方面进行分析,主要讨论了在该网络体系结构下实现相应的功能需求需要对GMPLS协议进行的扩展以及引入的新机制。
Mainly introduces the basic concepts and functional requirements of GMPLS-based multi-area / multi-layer network, and analyzes the functional requirements in two aspects. It mainly discusses that the GMPLS protocol needs to be extended to achieve the corresponding functional requirements under the network architecture As well as the new mechanism introduced.
