【摘要】 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。更多还原

【Abstract】 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 interconnections 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.更多还原
