The next step was to isolate the core technologies in today’s network and explore what savings might be physically possible for them. So the researchers moved their modeling closer to reality. But it was quantitatively almost meaningless, since nothing approaching the model could actually be built. That study proved that the question was worth pursuing. In this case, Samuel said, physical limits on transmission efficiency and switching energy would allow the network to be 10 12 times more efficient than today’s technology. In order to minimize the number of switching events there was no hierarchy” just a single, flat, fully populated mesh. Samuel said the project began within the Labs as a theoretical question: Just how much more efficient could the global network be? The researchers started with an idealized model: a network in which each endpoint was connected to every other by an ideal link, and each endpoint contained an ideal, massive switch to deal with all those connections. “The actual equipment to implement those savings will come later, after the technologies are identified.” “In the next five years we hope to identify the enabling technologies for three orders of magnitude improvement in efficiency,” explained Sam Samuel, Bell Labs executive director for Ireland and the UK. ![]() These disparate organizations have joined the cause to find three orders of magnitude in energy savings in global communications, even as the demand for bandwidth continues to grow exponentially. The Green Touch initiative, announced Monday, includes service providers AT&T, China Mobile, Portugal Telecom, Swisscom, and Telefonica academic research labs The Massachusetts Institute of Technology (MIT) Research Laboratory for Electronics (RLE), Stanford University Wireless Systems Lab (WSL), and the University of Melbourne Institute for a Broadband-Enabled Society (IBES) government and nonprofit research institutions CEA-LETI Applied Research Institute for Microelectronics (Grenoble, France), IMEC (headquarters: Leuven, Belgium), and The French National Institute for Research in Computer Science and Control (INRIA) and industrial labs Bell Labs, Samsung Advanced Institute of Technology (SAIT), and Freescale Semiconductor. Posted JanuBy Ron Wilson, Executive editor - EDN, Ī research project that apparently began as a speculation among Bell Labs engineers in Ireland and the UK has grown into a global consortium determined to reduce energy consumption in the global information network. Could the Global Network Be a Thousand Times More Efficient?
