Abstract
This work reports on the benefits of using energy-efficient grooming strategies in WDM mesh networks in terms of the overall network power consumption. We examine a key enabling node architecture called tap-or-pass (TOP) and demonstrate how it can support lightpath extension and lightpath dropping. Using these grooming concepts we propose several grooming strategies. Through extensive simulation, we demonstrate that, given a network with dynamic traffic requests, the proposed grooming strategies lead to considerable energy saving and comparable request blocking, in particular when the network load is moderate.
