Wavelength overprovisioning strategies for enhanced optical path restoration
2016 (English)In: International Conference on Transparent Optical Networks, IEEE Computer Society, 2016Conference paper (Refereed)
This paper proposes two wavelength overprovisioning strategies that can be used to improve the performance of path restoration in optical core networks under dynamic traffic conditions while considering single fiber link failure scenarios. The study presented in the paper shows that with the two proposed schemes it is possible to achieve nearly the same level of average connection availability and restorability typical of dedicated path protection schemes (i.e., 100%) with, on the other hand, better blocking probability performance.
