IP/MPLS网络与GMPLS网络互联的研究

Study on interconnections between IP/MPLS networks and GMPLS networks

文章研究了网际协议/多协议标签交换(IP/MPLS)网络升级为通用多协议标签交换(GMPLS)网络的过程中存在的几种演进模型,并重点分析了岛式模型。同时,还分析了MPLS网络和GMPLS网络互联时存在的问题、两种协议间的差异以及解决这些问题所采用的路由、信令和通道计算技术。

Several migration models existing in the process of upgrading IP/MPLS-based networks to GMPLS-based networks are studied, with the emphasis on the analysis of some island models. At the same time, the problems existing in the intercon- nections between these two kinds of networks, the differences between MPLS and GMPLS and the routes, Signaling and the path computation technology adopted in solving these problems are analyzed.
