This paper presents a novel scheme, Layered Internet Video Engineering (LIVE), in which network nodes feedback virtual congestion levels to video senders to assist both media-aware bandwidth sharing and transient loss protection. The video senders respond to such feedback by adapting the rates of encoded H.264/SVC streams based on their respective video rate-distortion (R-D) characteristics. The same...
For the optical packet-switching routers to be widely deployed in the Internet, the size of packet buffers on routers has to be significantly small. Such small-buffer networks rely on traffic with low levels of burstiness to avoid buffer overflows and packet losses. We present a pacing system that proactively shapes traffic in the edge network to reduce burstiness. Our queue length based pacing uses...
