GMPLS的动态路由机制研究

Dynamic Routing Mechanism of GMPLS

GMPLS由MPLS演进而来,它是MPLS向光层扩展的必然产物,路由技术是GMPLS的一项关键技术。这里简要回顾了MPLS技术,在此基础上对GMPLS中与路由相关的关键技术做了介绍,讨论GMPLS中现有的路由选择策略,论述基于GMPLS支持的对等网络模型对一种联合的网络结构及其控制平面的结构,最后提出基于GMPLS的网络中一种有QoS保证的动态路由机制。

GMPLS developed from MPLS is the inevitable result of MPLS to extend to the optical network. The routing technology is a key of GMPLS. The main technologies of GMPLS relative with routing is introduced based on the review of MPLS technology. The existing routing selection strategies in GMPLS are discussed. The structures of an integrated-network and its control plane are elaborated based on the peer network model supported by GMPLS. A dynamic routing mechanism guaranteed with QoS in networks based on GMPLS is proposed.
