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.
