摘要

文章对动态自相似业务在多纤IP over WDM网中的联合恢复问题进行了系统的研究

提出了3种联合恢复策略

算法的实现基于一种扩展的多纤分层图模型。通过大量的动态仿真实验

以业务中断率和恢复效率为性能指标

研究了上述3种恢复策略在不同自相似参数（突发度、均值和方差）中的性能

最后通过分析和比较得出联合通道恢复策略是最优的。

Abstract

In this paper

a systematic study is made of the integrated restoration of dynamic self-similar traffics in multifiber IP/WDM networks.Three integrated restoration strategies are proposed and the implementation of the algorithms is based on an extended Multifiber Layered Graph Model. Through extensive dynamic simulations

the performances of the above strategies

which are determined by the traffic interruption ratio and restoration efficiency

are studied under different parameters（Hurst

Mean and Variance） of the self-similar traffic model.By comparison and analysis

it is concluded that Integrated Path Restoration（IPR） is the best of the three restoration strategies.
