Integration of Elastic and Streaming Traffic: A Fixed Point Approach

We present a fixed point approach to evaluate the quality of service parameters of elastic traffic multiplexed with streaming traffic in multi-service network. First, we handle elastic traffic and streaming traffic separately, and then we derive a general fixed point formulation integrating both types of traffic in best effort networks. Then, we extend the application of this formulation to multi-service networks where priorities and bandwidth sharing schemes can be applied to different flows. Our approach is mainly oriented towards very large scale networks where traditional simulation techniques are not scalable, and where a large number of flows have to be evaluated in reasonable time. We assess the accuracy of our approach by means of event-driven simulations
