Cauchy Distribution for Jitter in IP Networks

In many real-time applications the quality of service (QoS) is dominated by jitter. In this paper RTT (round trip time) measurements were collected in order to find a probabilistic jitter model. From collected measurements the tail index was close to unit, this relates us to Cauchy's distribution. In this paper we show that the jitter has direct influence in the network performance. The purpose of this paper is to show how jitter dispersion affects the QoS in some applications.
