Abstract
End-to-end packet delays play a key role, along with other network impairments (e.g. packet losses), in shaping the performance of application traffic carried through the Internet, both via \TCP\ and by means of \UDP\ (e.g. real time applications). In this paper we present a statistical analysis of the packet Round Trip Delays (RTDs) in Internet. We measured ten very long and high resolution traces of packet RTD, collected in different network conditions. We analyze these traces under many aspects. Our main goal is to define a Wavelet based algorithm to generate a sequence of \RTDs\ that mimics the statistical behavior of measured data. Its main application is in modeling and simulation of \IP\ networks. We extensively test the algorithm to highlight its ability to match relevant features measured from Internet \RTD\ traces and its high accuracy when used to predict delay dependent performance metrics.
