Network Bandwidth Sharing for Transporting Rate-Adaptive Packet Video Using Feedback *

This paper presents a framework for network band-width sharing to transport rat,e-a,daptive packet video using feedback. We show how a weight-based band-width sharing policy can be used to allocated network bandwidth among competiug video connections and design a feedhack control algorithm using the avail-able bit rate (ABR) Hom control mechanism. A novel video source rate adaptation algorithm is int.roduced to decouple a video source's actual transmission rate from the rate used for the protocol convergence. We also demonstrate how an on-line minimum rate rene-gotia,tion and weight adjust,ment, niechanisms can be employed to furt,her enhanc? the Hexihilit,? of our feed-back control protocol.
