Media-Aware Rate Control

Streaming media transfers over the Internet are expected to behave in a TCP friendly manner and react appropriately to congestion similar to the way TCP does. However, our work shows that existing “TCPfriendly” protocols are not necessarily “media friendly”. In this paper, we present our findings on the impact of the TFRC protocol on streaming media quality. We propose the MARC (Media Aware Rate Control) protocol that, unlike TFRC, exhibits significant tolerance towards transient changes in background workload, while still maintaining TCP-friendliness.
