Abstract
VBR compressed video traffic is expected to constitute the majority of the B-ISDN network load in the immediate future. At the moment, the MPEG coding scheme is widely used for many types of applications. On account of the high burstiness and periodicity of the traffic generated by an MPEG encoder, it is crucial to obtain a model for the generation of sequences with the same statistical characteristics of real MPEG traces. In this paper, after demonstrating that intra-GOP correlation, that is, the correlation between frames belonging to the same GoP, has to be taken into account, an accurate model allowing the generation of an MPEG-like trace is proposed. Moreover, as the MPEG traffic has been demonstrated to be self-similar, that is, it presents a long-range dependence (LRD, the proposed algorithm applies a method based on the Fast Fourier Transform (FFT) in order to generate self-similar traces. This algorithm allows to generate a trace, imposing the SRD and LRD behavior and the prob...
