Topic overview
Green is a nice color, and the networks too should have their new painting. Indeed, large-scale ICT infrastructures expanded rapidly and their energy consumption grew drastically these last few years. As networks and data centers are generally prepared to face high load conditions, these infrastructures are under-utilized most of the time. There is, there, a clear direction to save energy. Network equipments, in particular, could be switched off when the load is low and switched on again when traffic increases, or when a failure happens, requiring redundant equipments to take the duty.
Research directions
Within the various optimization strategies, I am particularly interested into green routing, i.e. how to select routes in a network in order to ease energy savings. Core networks are usually over-provisioned, so that they can absorb peak traffic. They could, however, dynamically adapt their behavior to the load they experience. If routing avoids certain equipments (routers or even links via switches), these equipments can be put asleep until they are needed. QoS shall be preserved in every situation, though. We expressed this problem as an optimization problem, including the topological and traffic load aspects. We proposed various models of consumption for these networks and modeled the problem of selecting active equipments as a cooperative game. We evaluated the performance of the Shapley value as a ranking metric to select the active routers in real infrastructures, taking into account real traffic matrices.
