While Internet traffic is currently dominated by elastic data transfers, it is anticipated that\nstreaming applications will rapidly develop and contribute a significant amount of traffic in the\nnear future. Therefore, it is essential to understand and capture the relation between streaming\nand elastic traffic behavior. In this paper, we focus on developing simple yet effective approximations\nto capture this relationship. We study, then, an analytical model to evaluate the end-to-end\nperformance of elastic traffic under multi-queuing system. This model is based on the fluid flow\napproximation. We assume that network architecture gives the head of priority to real time traffic\nand shares the remaining capacity between the elastic ongoing flows according to a specific\nweight.
