摘要

本文提出了一种多光纤WDM网络生存性评估模型，该模型采用扩展分层图来共同优化波长路由和波长分配问题，并从流量工程角度对三种不同的边缘代价函数进行了评估。在共享保护和专用保护两种方案下，建立了线性规划方程，以最优确定工作光路和相应的保护光路。大量的仿真结果表明，与光纤共享保护和基于波长的代价函数提供了最佳的生存性。

Performance evaluation of survivable multifiber WDM network

This article proposes a survivability evaluation model for multifiber WDM networks, in which the extended layered graph is developed to jointly optimize the wavelength routing and wavelength assignment problems, and three different edge cost functions are evaluated in terms of traffic engineering. Linear programming (LP) equations are formulated to optimally determine the working lightpath and the corresponding protection lightpath under the schemes of shared protection and dedicated protection. The extensive simulations show that shared protection with the fiber and wavelength-based cost function provides the best survivability.
