Abstract :
Hierarchical traffic grooming facilitates the control and management of multigranular WDM networks. We define the hierarchical virtual topology and traffic routing (H-VTTR) problem, the grooming-specific subproblem of traffic grooming, and we present a suite of ILP formulations to solve it. The formulations represent various tradeoffs between solution quality and running time.
