Abstract:

This work proposes a distributed and adaptive mechanism for saving energy in IP/MPLS over WDM networks by switching off router line cards according to the traffic variability in the network. The proposed mechanism optimizes the traffic routing and adapts the IP topology to the traffic that is actually carried in the network. This is done by re- computing the path of each traffic flow several times during a day when their requested capacity changes. The routing is performed by using a specific cost function, named V-Like, to compute link weights into the shortest path routing algorithm. The proposed solution is compared with a static energy-aware heuristic algorithm proposed in the literature; results show that it is possible to save from 35% up to 50% of energy with respect to the static case, depending on the traffic load.
