The paper considers the problem of establishing robust routes for multi-granularity connection requests in traffic-grooming WDM mesh networks and proposes a novel Valiant load-balanced robust routing scheme for the hose uncertain model. Our objective is to minimize the total network cost when construct the stable virtual topology that assure robust routing for all possible multi-granularity connection...
In this paper, we propose a novel method to address the problem of designing virtual topology over WDM networks under traffic demand uncertainties. We present a traffic model under uncertainties. The optimization goal of virtual topology design is defined as minimizing the maximum value among p percentiles of the traffic distribution on all light-paths. Correspondingly, we propose a heuristic algorithm...
In this paper, we introduce a novel oblivious routing scheme based on valiant load-balancing for the model of polyhedral uncertainty (i.e., hose model), and the scheme is implemented with traffic-grooming approach in WDM mesh networks. Considering that a high-speed connection request in optical networks is difficult to be divided into low-speed connections, we propose the method of hose-model separation...
