Title : “Energy Aware Traffic Engineering in Wired Communication Networks”
The reduction of power consumption in communication networks has become a key issue for both the Internet Service Providers (ISP) and the research community. Actually, power consumption of networking devices scales with the installed capacity, rather than the current load. However, actual traffic is subject to strong day/night oscillations. Thus, many devices are underutilized, especially during off-peak hours. In this context, we apply resource consolidation, a known paradigm for the reduction of the power consumption, consisting in having a carefully selected subset of network devices entering a low power state, and using the rest to transport the required amount of traffic. This is possible without disrupting the Quality of Service (QoS) offered by the network infrastructure. In this thesis work, we present different techniques to perform resource consolidation in backbone IP-based networks, ranging from centralized to distributed solutions, and facing different technological scenarios.
