Source traac streams as well as aggre-gated traac ows often exhibit long-range-dependent (LRD) properties. In this paper, we model each traac stream component through the multiplicative multi-fractal counting process traac model. We prove that the superposition of a nite number of multiplicative multifractal traac streams results in another multi-fractal stream. This property makes the multifractal traac model a versatile tool in modeling traac streams in computer communication networks. There, a node is loaded by a traac ow resulting from the super-position of source streams and aggregated LRD (and other) streams. The structure and the burstiness of the superimposed process is studied, and useful mathematical relations are obtained.
