Delay variation model for RTP flows in network with priority queueing

Abstract

A description of queuing delay mechanisms for VoIP traffic is a complex ask. This paper deals with a mathematical computational model that is able to predict a estimated delay of packets in RTP flows, especially dealy variation in routers handling RTP packets in priority queue. We applied M/D/1 queuing model and we expressed a probability of RTP packet waiting in the queue. We describe all partial VoIP delay components and mechanisms, its generation, facilities and mathematical formulations. We present new approach to the delay variation model and we have confirmed its validity by an experiment.
