Abstract

In this paper, we propose analytical model of Virtual Link used in the Service Overlay Networks. The Virtual Link exploits Selective Repeat ARQ scheme with time constrained number of retransmission and the playout buffer mechanism. Our model allows deriving equations that express trade-off between loss and delay characteristics experienced by packets transferred through VL. The main innovation of our model is the ability to cope with variable delay experienced by packets transferred by underlying network. Following the analytical model, we propose a method for Virtual Link dimensioning. The accuracy of the proposed model and dimensioning method is illustrated by simulation results
