Paper Abstract

The goal of this paper is to provide a feasible and flexible mechanism for variable bit rate (VBR) video transmission and to achieve high network utilization with statistical Quality of Service (QoS). In this paper, we employ a piece-wise constant rate smoothing algorithm to smooth the video coder outputs and propose a simple algorithm to determine the renegotiation schedule for the smoothed streams. In order to transmit video streams with renegotiation-based VBR service, we suggest a connection admission control (CAC) based on Chernoff bound using a simple yet quite accurate 'binomial' traffic model. The experimental results show that our proposed method provides an easy and robust mechanism to support real- time video transmission in both homogeneous and heterogeneous connection environments.
