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.
