Title
Optical Communications Efficient multi-layer traffic grooming in an IP/MPLS-over-optical network
Abstract
Traffic grooming in meshed optical networks is an important research topic due to the vast difference between the bandwidth requirements of IP/MPLS traffic demands and the capacity of a wavelength. In this paper, we present, evaluate and compare several traffic grooming strategies for a multi-layer IP/MPLS-over-meshed optical network, which take into account the unidirectional nature of IP. Applying a proper multi-layer grooming algorithm also implicates designing a cost-efficient IP/MPLS topology suited for the offered traffic. This study shows that a very promising traffic grooming strategy is the one that deploys a sophisticated capacity installation algorithm in combination with the idea of charging the IP/MPLS layer for the capacity it consumes in the optical layer. Such an iterative, charging-based approach allows significant savings in the overall network design cost compared to a more simple approach. It also allows gradually installing extra line-systems in the optical network as traffic increases. Copyright (C) 2005 AEIT.
