A Simple Formula for End-to-End Jitter Estimation in Packet-Switching Networks

In this paper, an analytic approximation is derived for the end-to-end delay-jitter incurred by a periodic traffic with constant packet size. It is assumed that the periodic traffic is multiplexed with a background packet stream under the FCFS service discipline in each queue along the path to its destination. The processes governing the packet arrivals and the packet sizes of the background traffics are assumed to be general renewal processes. A very simple analytical approximation is derived and its accuracy is assessed by means of event-driven simulations.
