Abstract

Content Delivery Networks (CDN) play an important role in today's video distribution system. While its advantage of efficient content delivery is well understood, the energy consumption of the video CDN system needs to be understood since energy saving recently has become a key challenge for the system designers and operators. This paper investigates the energy efficiency aspect of a video CDN system by firstly analyzing and defining the energy efficiency of a video CDN system, followed by two possible energy efficiency improvements, which are based on the idea of intelligent coordination among edge video servers.
