Network-wide Proportional Services [articol]

Abstract

We proposed an end-to-end relative differentiation scheme to assure Quality of Services of IP network in a predictable manner, called network-wide proportional service. Quality of Service is applied to flow aggregates and the performance parameter of the classes is the goodput of these flows. We also present an algorithm, which computes the bandwidth of the flows required to sustain the model and the considered architecture. We verify then the proposed algorithm by simulations for both UDP and TCP traffic.
