智能光网中的联合路由

Integrated Routing in Intelligent Optical Networks

在IP/MPLS智能光网络中的LSP路由分为独立路由和联合路由两类。由于综合考虑了光层和IP层的可用资源信息和拓扑信息,联合路由能够提供比独立路由方案更高的资源利用率。文中提出了联合路由算法的设计目标,综述了联合路由算法的研究现状,并给出了下一步的研究方向。

LSP routing issues in IP /MPLS intell igent optical networks can be addressed by ei-ther separated or integrated routin g schemes.Because the available resource and topology information on both optical and IP layer can be emp loyed,integrated routing has more e fficient resource utilization than separated routing.In this paper,several design objectives of inte grated routing are introduced as well as its recent developments.Fin ally,future research is presented.
