Not too long after its emergence, the Internet became an integral part of everyday lives of men in modern societies. It constantly fuels growing opportunities for new advanced services which can better respond to quickly changing society needs. Previously such services often led to increases in energy consumption which is today in a strong contrast with the global drive for a greener and energy more efficient environment. We need network infrastructures which will support these growing needs but at the same time will also stay zero-carbon emission complaint. Such requirements are more imperative today than were ever before. In optical IP networks the power consumption could be reduced via green photonics and concepts known as green networking . In line with these concepts we proposed a novel energy savings approach based on so called “node hibernation” technique. This approach is designed to help reduce network power consumption and optimise its energy usage by taking advantage of a hibernation algorithm we have developed. Its implementation into the network management structure will save the energy, operating cost to network operators and will deliver reduced carbon footprint.
