主　　题：routing and wavelength assignment power consumption connection holding time dynamic WDM optical network 

摘      要：The challenges imposed by environmental issues,such as global warming and the energy crisis,are demanding more responsible energy usage,including in the optical networking *** optical transmission networks,most of the electrical power is consumed by the optical-electrical-optical conversion in optical *** optical network control plane technologies allow idle optical repeaters to be put into a low-power sleep *** by this,we propose a novel power-efficient routing and wavelength assignment(RWA) algorithm,called *** HTAPE algorithm exploits the knowledge of the connection holding times to minimize the number of optical repeaters in the active mode,and hence reduce the total electricity consumption of the optical *** test the new algorithm on the typical CERNET and USNET *** with traditional RWA algorithms without holding-time-awareness,it is observed that the HTAPE algorithm yields significant reductions in power consumption.
