Energy saving is urgent issue for sustainable deployment of advanced Information and Telecommunications Society. We propose to convert variation in logical domain into reduction of energy consumption based on characteristics of physical domain. While recent metro/core optical transceivers features functions to compensate signal impairment in order to provide longer-range transmission, circuitry for impairment compensation consumes a large fraction of energy in the system. Adaptive selection of the modulation format depending on traffic requirement offers significant energy saving by inactivating unneeded compensation circuitry. Circuitry can be put to sleep according not only with throughput, but also with required compensation performance. Numerical study on a domestic traffic variation and topology models exhibited significant outstanding energy saving of 82% for the core network and 84% for the metro network. Proposed system is highly compatible with existing optical communication system. It is expectable that the proposed architecture will contribute to the ongoing development of network systems. |
