A Comparative Performance Study of Load Adaptive Energy Saving Schemes for IP-Over-WDM Networks

Load adaptive energy saving schemes for backbone IP networks use dynamic transport circuit services to adapt the active network resources to the current traffic demand in order to reduce the network's energy consumption. Recently, several approaches, categorized as Switch-Off schemes, have been proposed which attempt to reduce the energy consumption of already existing networks by switching off IP ports and links during periods of low traffic. Although it has been shown that these schemes can notably decrease the network's energy consumption, they are prone to instabilities in the IP routing service and decreased resilience due to reduced connectivity, and they may induce monitoring reconfigurations.
