Time: Wednesday, 9:00AM - 10:30AM, April 17, 2013 Location: IEEE Conference on Computer Communications (INFOCOM), Turin, Italy URL: http://infocom.di.unimi.it/index.php/panel.html Panel Moderator: Daniel C. Kilper, Columbia University, New York, NY, USA Technical Support: IEEE Technical Subcommittee on Green Communications and Computing (TSCGCC) Panelists: -Sujata Banerjee, HP Labs, Palo Alto, USA -Antonio Capone, Politecnico di Milano, Italy -Flavio Cucchietti, Telecom Italia, Italy -Kerry Hinton, Univ. of Melbourne, Australia -Louise Krug, British Telecom, UK -Christoph Lange, Deutsche Telekom, Germany, Abstract: Historically, network equipment was not designed with power adaptation operation capabilities and remained powered at near the maximum rating for a given configuration, often with less than 15% variation with load. Load proportional energy use therefore is an important step towards improved efficiency. In mobile and fixed access networks power adaptation methods are already finding use. There are two general strategies toward achieving load proportionality: one is to adapt the hardware operation in speed and/or voltage in response to the traffic load; and the second is to power off or put to sleep components or entire line cards and systems. Placing equipment to sleep often provides the best energy reduction, but comes at a cost in terms of wake up times, traffic disturbance during transitions, and overhead requirements. Rate adaptation can be far more flexible, but may have limited benefit and in some cases can incur performance penalties. Much research has been dedicated to these issues recently. This panel will address the broad question of what the prospects are for these technologies to impact communication networks from access to the core and considering mobile and fixed systems. _______________________________________________ IEEE Communications Society Tech.
