Increasing customer requirements for ‘always-on’connectivity brings with it increased energy consumption across any ICT infrastructure. The growth in multimedia applications, social computing and on-demand streaming services is driving the deployments of Next Generation Networks by network operators in support of service providers. Coupled to this is the increased awareness of the need to reduce the carbon footprint of maintaining the communications infrastructure and companies are now exploring methods and protocols to embed more energy efficient components, protocols, and optimisation technologies within their infrastructures. In this paper several energy efficiency techniques are reviewed, and their potential impact is discussed. An initial simple model for calculating the savings to be gained is presented.
