In the next 10 to 15 years the Internet will undergo a substantial increase especially with respect to the bandwidth required by end-users. Since the current Internet already consumes a not-negligible percentage of the total world electricity, reducing the energy consumption of telecom networks is expected to become an increasingly-important challenge, being unacceptable that the Internet energy consumption...
Since the energy crisis and environmental protection are gaining increasing concerns in recent years, new research topics to devise technological solutions for energy conservation are being investigated in many scientific disciplines. Specifically, due to the rapid growth of energy consumption in ICT (Information and Communication Technologies), lot of attention is being devoted towards "green"...
We present an approach to evaluate energy efficiency of mixed-line-rate (MLR) optical networks. A comparative study of energy efficiency of MLR and single-line-rate (SLR) networks shows that MLR is more energy efficient than SLR networks.
