A novel method for estimating energy consumption of networks at the national scale is presented. Accurate estimations of network energy consumption are increasingly important because of continuously increasing network traffic and the need to assess emerging energy technologies to achieve overall energy efficiency. However, direct estimations are not practical because of the complex, widely diverse,...
Exploiting photonic technologies will be the best way to create bandwidth abundant and energy efficient future networks, however, their introduction remains limited. The barriers and possible solutions for future networks are discussed.
Given the twin bottlenecks of current IP transport, inadequate throughput and excessive power consumption, exploiting photonic technologies will be the best path to creating bandwidth abundant and energy efficient future networks. The large throughput optical cross-connect node and optical path tunneling functions are effectively attained with the introduction of higher order optical paths, wavebands...
Future enhancements in optical path layer enabling technologies are highlighted. The role of waveband paths in creating the next generation transport network is discussed. Some state-of-the-art key enabling technologies are demonstrated.
