    The delivery of multimedia services easily faces the problem of guaranteeing required delay performance for the delay sensitive service components. The problem is especially severe with isochronous service components, such as voice and video. The transport network should guarantee, e.g., required bit rate, end-to-end delay, delay variation and error ratio performance, for each tributary of a multimedia service stream regardless of the other traffic or the number of network nodes traversed en route. In this paper, we study change of delay variation of constant bit rate traffic in presence of Poisson and MMPP distributed background load. A simulation model is deduced and simulation results, based on the model, are presented. Finally, some confirming measurement results are given.
