摘要

随着波分复用（WDM）技术的迅速商用化

骨干网络传输带宽呈现爆炸式增长的趋势

这使得网络生存性变得越来越重要。传统的网络生存性包括保护和恢复两种机制

而恢复机制直接影响着网络失效以后其承载业务的可靠性。文章综合前人的研究成果

从3个角度出发

提出了3种不同的恢复算法

并通过仿真数据对这3种算法性能进行了分析。

Abstract

With the rapid commercial applications of the WDM technology and the explosive growth of the transmission bandwidth of backbone networks

network survivability has become increasingly more important.The traditional network survivability includes protection and restoration mechanisms and the latter has direct effects on the reliability of the traffics on the failure of networks.Based on the research results in this field

we present three different restoration algorithms from three angles and analyze their performances in terms of restoration probability and resource utilization through simulation data.
