Researchers from the Centre for Energy-Efficient Telecommunications (CEET) demonstrated the first comprehensive tool to measure and model energy of routers in telecommunications networks at the University of Melbourne.
The Universal Router Energy Model takes a global approach to energy measurement increasing understanding about energy consumption. The model measures the volume and characteristics of data flowing through routers in order to calculate the overall energy consumption across the network. Importantly, the model is able to differentiate between different types of traffic such as video and VoIP.
In the past telecommunications networks have been built without regard to their energy-efficiency. The technique was demonstrated today at the Australian Broadband Applications Laboratory, the research team showed how the Model can be used to measure energy consumption across two different paths through a network. The ability to model different data paths will provide services providers an opportunity to choose the most energy efficient path for data in the future.
Professor Rod Tucker, CEET Director stated, “The model is a breakthrough in increasing the sustainability of telecommunications networks. Accurate measurement and modelling will provide the data that the industry needs to deliver efficient solutions in the face of growing demand”.
Dr Thierry Klein, Head of Green Research Bell Labs and Chairman of the GreenTouch Technical Committee said, “CEET is a true global leader and visionary in the drive for energy-efficient and sustainable computing and networking. The work demonstrated today is an essential building block of GreenTouch’s agenda to increasing the energy efficiency of global telecommunication networks and the researchers in CEET are critical to the success of GreenTouch&rdquot.
The Model was developed through the collaboration between CEET and GreenTouch, a global consortium looking to reduce the energy consumption of telecommunications networks by a factor of 1,000. The work demonstrated by CEET forms the basis of emerging international standards to reduce the carbon footprint of telecommunications industries.

CEET was launched in March 2011 by Alcatel-Lucent, Bell Labs, the University of Melbourne, and the Victorian State Government as the world’s first research centre exclusively dedicated to energy-efficient telecommunications technologies. Its research efforts cover a broad range of telecommunications network infrastructures and how those elements can increase their energy efficiency.
