Alcatel-Lucent Unveils Application to Measure Carbon Footprint of Network


Helping operators better understand the DNA of their network, Alcatel-Lucent has unveiled a new application developed by its research arm, Bell Labs, that network operators and others can use to explore how the use of the latest technologies can dramatically reduce energy consumption, costs and the carbon footprint of their networks.

This easy-to-use G.W.A.T.T. – Global ‘What if’ Analyzer of NeTwork Energy ConsumpTion app – forecasts trends in energy consumption and efficiency based on a wide variety of traffic growth scenarios and technology evolution choices.

G.W.A.T.T. provides a view of the entire network, showing how much power is consumed at each point in the network. This make it possible for G.W.A.T.T. to quickly identify ‘hot spots’ in a network where the most energy is consumed, and also provides a way to identify  how different technologies can make the network more efficient. The application was developed as part of Alcatel-Lucent’s commitment to dramatically reducing the energy consumption and operational costs of information and communications technology (ICT) in the face of dramatic growth in data traffic and associated energy use impacts.

The rapid adoption of smart phones and tablets are driving up daily Internet traffic dramatically, and forecasts indicate that it will increase up to 85 times by 2017 compared to 2010. By 2017 more than 5 trillion gigabytes of data will pass through the network every year; this is the equivalent of everyone on the planet tweeting non-stop for more than 100 years. G.W.A.T.T. provides a roadmap of how to support this growth in a sustainable and economically viable way.

Over time, Alcatel-Lucent will continually expand the capabilities of G.W.A.T.T., refining its modeling capabilities, adding new scenarios and technologies, and including new technologies and architectures currently being investigated by Bell Labs and the GreenTouch consortium.

Dr. Peter Thomond, Managing Director at Clever Together and Author of the Global e-Sustainabiliy Initiative’s and Microsoft’s report “Enabling Technology 2020: The Carbon Impact of Cloud Computing”, said: “My colleagues and I at Imperial College, Reading University and Harvard Business School have spent a lot of time in recent years analysing the potential for technology to enable or undermine carbon abatement and environmental pollution across the globe. I believe that G.W.A.T.T. offers a breakthough in helping the ICT and telecoms sectors to understand how different technologies, alone and in combination, will impact the energy consumption of their networks.  As demand for broadband services and applications skyrockets, the team at Alcatel Lucent should feel proud that they have made a meaningful contribution to the tool box of those fighting to keep energy consumption in check.”

Marcus Weldon, Corporate Chief Technology Officer (CTO) of Alcatel-Lucent and Bell Labs President said: “G.W.A.T.T. is more than just a modeling tool.  It is intended to guide future product and architecture evolution by allowing network operators and ICT architects and engineers to have a complete view of the energy impact of the decisions they make regarding what new technologies to introduce into their networks and when. It also can clearly explain which technology investments can have the biggest impact on energy consumption.”
