We study the m-trail (monitoring trail) allocation problem in all-optical WDM mesh networks for achieving fast and unambiguous link failure localization. The existing ILP is not feasible for solving the problem in large-size networks. A heuristic RCA+RCS can find feasible solutions in a shorter running time, but it is a randomized algorithm. More importantly, RCA+RCS suffers from the disjoint trail...
It has been recognized that light-trees should be as balanced as possible in order to guarantee an adequate signal quality and to scale to large destination sets, if power losses are taken into account when routing connections in mesh WDM networks. In this paper we study the problem of constructing such balanced light-trees. We propose a novel algorithm, called extended shortest path heuristic algorithm...
