【摘要】 随着网络的快速发展,网络流量,特别是突发流量的激增,给当前光骨干网带来越来越重的负担。CMPLS是提高网络性能的一种有效方法。通过增加不同粒度和种类的转发和交换能力,GMPLS比MPLS更适合光骨干网。本文主要介绍GMPLS流量工程机制,并对其进行了仿真。同时也对路径保护和恢复进行了简单探讨和仿真。仿真结果说明GMPLS可对进入网络的流量进行规范,对故障处流量进行有效的疏导,使网络更加稳定地运行。更多还原

【Abstract】 With the fast development of the network, the traffic, especially the explosively increasing burst traffic, bring heavier burden to the optical network. GMPLS is an efficient approach of improving network behavior. GMPLS, which has ability of forwarding and switching packets of multi-granularity and different type, is more suitable than MPLS for optical network. In this paper, we explain the traffic engineering in GMPLS, and make simulation. We also do simply discussion and make simulation for path protection and recovery. The result show that, GMPLS have the ability to normalize the traffic, make efficient conduction of failure traffic, and let the network running more stably.更多还原
