Abstract
In this paper, we study the source clock frequency recovery method for variable bit rate (VBR) video services using traffic shaping in B-ISDN. We propose a three-level traffic shaper (TLTS) which is able to limit not only the maximum cell rate but also the minimum cell rate for VBR video sources. Modeling a VBR video source as a two-state Markov-modulated Poisson process (MMPP), we numerically evaluate the cell loss probability, the underflow probability, and the maximum delay as performance measures. Using TLTS, we extend the existing constant bit rate(CBR)-based synchronous residual time stamp (SRTS) method to the source clock frequency recovery in VBR video services, and develop a dimensioning procedure of the TLTS. Finally a numerical example is presented to demonstrate the practicality of the dimensioning procedure.
