Connection provisioning constrained to fault localization in all-optical networks

Fault localization is becoming a critical issue in all-optical networks. The Limited Perimeter Vector Matching (LVM) protocol is a novel fault localization protocol for localizing single-link failures in all-optical networks. In this paper, we study the fault localization optimization problem by applying the LVM protocol where the traffic demands (or lightpath requests) are known a priori. Given the traffic demands, the fault localization optimization problem aims to optimize the traffic distribution so that the fault localization probability in terms of the number of localized links can be maximized. Moreover, the solution to the problem can also provide the maximum number of wavelengths needed on each link to obtain the maximum fault localization probability.
