DESCRIPTION:Nedeljko Vasic\nEnergy consumption of the Internet is already 
 substantial and it is likely to increase as operators deploy faster equipm
 ent to handle popular bandwidth intensive services\, such as streaming and
  video-on-demand. Existing work on energy saving considers local adaptatio
 n relying primarily on hardware-based techniques\, such as sleeping and ra
 te adaptation. We argue that a complete solution requires a network-wide a
 pproach that works in conjunction with local measures. However\, tradition
 al traffic engineering objectives do not include energy. This talk present
 s Energy-Aware Traffic engineering (EATe)\, a technique that takes energy 
 consumption into account while achieving the same traffic rates as the ene
 rgy-oblivious approaches. EATe uses a scalable\, online technique to sprea
 d the load among multiple paths so as to increase energy savings. Our exte
 nsive ns-2 simulations over realistic topologies show that EATe succeeds i
 n moving 21% of the links to the sleep state\, while keeping the same send
 ing rates and being close to the optimal energy-aware solution. Further\, 
 we demonstrate that EATe successfully handles changes in traffic load and 
 quickly restores a low overall energy state. Alternatively\, EATe can move
  links to lower energy levels\, resulting in energy savings of 8%. Finally
 \, EATe can succeed in making 16% of active routers sleep.
