Wavelength Reusability of Failure Protection Based on Rerouting in Wavelength-routed Optical Networks
摘要
Abstract
This paper investigates the wavelength efficiency of failure protection based on rerouting in wavelength-routed optical networks. In order to study the impacts of different traffic pattern over the efficiency, a parameter, wavelength reusability ρ, is introduced as an evaluation criterion. Performance of different failure protection methods and the influence of different routing schemes over the performance are investigated. The routing and wavelength assignment problem involved in failure protection is formulated as integer linear programming problem, relevant heuristic optimization algorithms are also developed, numerical results are presented and discussed in detail.关键词
