Approximate Analysis of Coupled Queueing for Self-Similar Video Traffic in ATM Networks

摘要

In this paper, we propose a dynamic scheduling method for self-similar variable bit rate video traffic in ATM networks. We analyze the proposed scheme in coupled queueing systems which have been used extensively in the modeling of computer and communication systems. Diffusion approximations methods are used to decouple a queueing system which represents an ATM network node into separate G/G/1 queues. Real MPEG video traces are used in discrete event simulation. Results are compared with the approximation, and are found to work very well under different traffic conditions.
