Improving energy efficiency of video on demand services

Abstract

The energy consumption of the Internet is anticipated to be one of the main contributors to global energy consumption in the coming decades. As a result, renewed attention has been given to the energy efficient design and operation of network services. The video on demand (VoD) service is expected to be one of the most prominent services through the Internet in the near future. Due to the enormous energy consumption arising from storage and transport of movies, energy efficient design and operation of VoD systems are important considerations. In this paper, we formulate energy consumption models to analyze the energy consumption arising from storage and transport of movies in VoD systems. We..
