Energy-efficient congestion control


Various link bandwidth adjustment mechanisms are being developed to save network energy. However, their interaction with congestion control can significantly reduce throughput, and is not well understood. We firstly put forward an easily implementable link dynamic bandwidth adjustment (DBA) mechanism, and then study its iteration with congestion control. In DBA, each link updates its bandwidth according to an integral control law to match its average buffer size with a target buffer size. We prove that DBA reduces link bandwidth without sacrificing throughput-DBA only turns off excess bandwidth-in the presence of congestion control. Preliminary ns2 simulations confirm this result.
