GreenTouch, the global consortium of ICT firms doing joint energy reduction research has set itself a target of 2015 to deliver demonstrations of key components, architectures and technologies needed to cut energy consumption of network operations of 90% by 2020.
The consortium believes a reduction in is possible based on network models, technologies and protocols developed both inside and outside of the consortium over the past three years.
Today’s networks operate well above the minimum energy required for communication and the goal is to increase network energy efficiency by a factor of 1000 and demonstrate in 2015 the architectures and technologies that will enable this increase in the real networks of 2020.
Founded in 2010, the consortium’s formation was motivated the rate of energy consumption in ICT networks rapidly increasing as a result of exponential growth in information and communication traffic on those networks being projected to do so unless substantial energy reductions are initiated.
GreenTouch’s initiative in 2010 was based on research conducted by Bell Labs, which concluded that ICT networks had the potential to be four orders of magnitude (10,000 times) more efficient (than 2010 levels). This conclusion is based on a fundamental analysis of the underlying components of ICT networks and technologies (optical, mobile, processing, routing, architecture, etc.) and their known physical limits.
The consortium has 53 members encompassing all the stakeholders of the ICT value chain and academics and research institutes.
GreenTouch provides the platform for innovative researchers, engineers and technology experts from around the world to work together and accelerate their efforts from idea creation over demonstration to standardization and policy influencing. GreenTouch has some 16 projects underway. These projects are being developed and delivered by working groups composed of volunteer representatives from GreenTouch member companies, directed by the GreenTouch Technical Committee.
To date, the consortium has publicly demonstrated two significant projects in the areas of mobile and wireline networks, the Large Scale Antenna System and Bit-Interleaved Passive Optical Network (Bi-PON) technology.
