An operator, called the dual-rate transfer function, describing a dual-rate discretized continuous-time system is presented. It can be easily related to single-rate transfer functions of the same system, and its parameters can be experimentally estimated. Based on these models, two adaptive control strategies are outlined, and some results are illustrated by a simple example. Copyright 0 1996 E...

On high-speed networks, the round trip delay from source to intermediate node and back is relatively large compared with packet transmission times; thus, the window-based method of flow control does not react quickly enough to prevent congestion and large delay. An alternative method is to employ a rate-based flow control scheme, in which each node is assigned a maximum rate and an average rate...

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 Rat...
