Models for still image transmission over broadband networks

Abstract

A statistical source model for a still image coder is presented and used to derive two queuing models for still image transmission over broadband networks. The first model is based on queuing the image data cells and is analyzed using an M(/sup x/)/D/1 queuing system. The second model is based on queueing the requests for images and is analyzed as an M/G/1 queuing system. The queuing delay is very short for both models. However, the results from the M(/sup x/)/D/1 model (queuing the image data) indicate that very large buffer sizes are required. The M/G/1 model is suitable for analyzing the behavior of an entry node to a network.<>
