Statistical traffic modeling of MPEG frame size: Experiments and Analysis
Abstract
For guaranteed quality of service (QoS) and sufficient bandwidth in a communication network which provides an integrated multimedia service, it is important to obtain an analytical and tractable model of the compressed MPEG data. This paper presents a statistical approach to a group of picture (GOP) MPEG frame size model to increase network traffic performance in a communication network. We extract MPEG frame data from commercial DVD movies and make probability histograms to analyze the statistical characteristics of MPEG frame data. Six candidates of probability distributions are considered here and their parameters are obtained from the empirical data using the maximum likelihood estimation (MLE). This paper shows that the lognormal distribution is the best fitting model of MPEG-2 total frame data.
