Bandwidth renegotiation scheme for VBR video services

E. Casilari, F. Sandoval

Open publisher page 2 citations

Abstract

The authors show how the existence of long term variability in variable bit rate (VBR) video traffic imposes the need for bandwidth renegotiation. In particular, two simple scenarios with a fixed renegotiation interval are considered. Using a real MPEG trace the renegotiation scheme is evaluated to prove its benefits in terms of bandwidth gain and quality of service. The problem of renegotiation demonstrates the need for modelling long term variability in VBR traffic.
