Development of IPDV of a Real Time Micro Flow Along the Network Path of a Differentiated Services Network

based on aggregation of traffic as opposed to per flow traffic. When DiffServ is used in a real time traffic environment it is important to study the effects of traffic aggregation on quality of service parameters. Instantaneous packet delay variation (IPDV) is one of the most commonly used quality of service parameters for real time traffic. In this paper we study how IPDV of a micro flow builds up, from the source to the destination, in a DiffServ network. We define the parameters that influence IPDV of a flow at a network node through our simulations and represent them in an abstract analytical model.
