Dynamic bandwidth allocation for VBR video sources in ATM based BISDN
With variable bit rate (VBR) video sources, adjacent slices in a frame are strongly correlated with each other. This is also the case for the frame represented by frame correlation. VBR video sources can be statistically characterized by peak rate, average rate, and standard deviation of the rate of generated cells. Taking account of each correlative and statistical properties, VBR video sources can be more efficiently transmitted by estimating the required bandwidth. In this paper, we propose a scheme that predicts and allocates dynamically transmission bandwidth for VBR video sources in ATM based BISDN. The performance of the proposed scheme is evaluated through simulations. Simulation results show that the proposed scheme is superior to the conventional ones in terms of bandwidth utilization and cell loss rate.<>
