The GreenTouch industry consortium says new technologies could cut power consumption by 90 percent
Networks could use far less energy by 2020 even though they'll be carrying much more traffic, an industry group says.
The GreenTouch consortium, formed in 2010 to speed up progress on more efficient networks, says it has identified technologies that together could cut network power needs by 90 percent even in the face of rapidly growing data demand. The group of equipment vendors, component makers and service providers will present that conclusion in a report due in mid-June.
"There is potential with these new technologies to support the traffic growth and still make the energy consumption go down," said Thierry Klein, chairman of GreenTouch's technical committee. Klein also leads green research at Alcatel-Lucent's Bell Labs division.
The tools that make this possible include new devices, components, algorithms, architectures and protocols, Klein said. All have been proved in labs, he said. The potential energy savings represents a comparison between a 2010 network with that year's traffic levels and a theoretical 2020 network with projections of traffic amounts for that year.
