Measuring, Modelling and Understanding Internet Traffic
PRODUCED ON ACID-FREE PAPER MEASURING, UNDERSTANDING AND MODELLING INTERNET TRAFFIC Nicolas Hohn SUBMITTED IN TOTAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY JULY 2004 DEPARTMENT OF ELECTRICAL AND ELECTRONIC ENGINEERING THE UNIVERSITY OF MELBOURNE AUSTRALIA A mes parents, pour leur amour, encouragement et constant support, sans qui rien ne serait. iii Abstract This thesis concerns measuring, understanding and modelling Internet traffic. We first study the origins of the statistical properties of Internet traffic, in particular its scaling behaviour, and propose a constructive model of packet traffic with physically motivated parameters. We base our analysis on a large amount of empirical data measured on different networks, and use a so called semi-experimental approach to isolate certain features of traffic we seek to model. These results lead to the choice of a particular Poisson cluster process, known as Bartlett-Lewis point process, for a new packet traffic model. This model has a small number of parameters with simple networking meaning, and is mathematically tractable. It allows us to gain valuable insight on the underlying mechanisms creating the observed statistics. In practice, Internet traffic measurements are limited by the very large amount of data generated by high bandwidth links. This leads us to also investigate traffic sampling strate- gies and their respective inversion methods. We argue that the packet sampling mechanism currently implemented in Internet routers is not practical when one wants to infer the sta- tistics of the full traffic from partial measurements. We advocate the use of flow sampling for many purposes. We show that such sampling strategy is much easier to invert and can give reasonable estimates of higher order traffic statistics such as distribution of number of packets per flow and spectral density of the packet arrival process. -

ABSTRACT From the viewpoint of a service provider, demands on the network are not entirely predictable. Traffic modeling is the problem of representing our understanding of dynamic demands by stochastic processes. Accurate traffic models are necessary for service providers to properly maintain quality of service. Many traffic models have been developed based on traffic measurement data. This chapter gives an overview of a number of common continuous-time and discrete-time traffic models. -

Teletraffic Engineering Course Brief and Outline
f Electr o ica ol l a School of Electrical and Information Engineering o h n c d S University of the Witwatersrand, Johannesburg I n g f n o i r r m ee at in ion Eng ELEN7015 { Teletraffic Engineering Course Brief and Outline: 2015 Course Lecturer: Dr L. Cheng Room: CM4 380 Tel: 011 7177228 Email: [email protected] 1 Course Background and Purpose Teletraffic engineering, based on teletraffic theory, provides the means to analyse, design and monitor networks to ensure that the networks carry end user and signalling information to the satisfaction of end users. Teletraffic started early in the history of telephony with a Danish School- master wondering about the capacity of the village telephone exchange. As switched circuits grew in complexity, a large body of theory and practice emerged for engineering telephone networks to carry voice traffic with acceptable quality of service using measures such as the probability of an attempt to make a call failing because all equipment is busy. With the emergence of packet switched networks the subject expanded. Approaches to engineering packet switched networks to carry user packets have much in common with switched circuit networks but required extensions. Engineering of packet networks for traffic also has its own nuances. Teletraffic theory is rooted in probability. Ideally, the student should be well versed in probability concepts. However, as this is often not the case, the course is structure with the opportunity to learn or refresh key concepts in probablity and to reinforce this learning through computer exercises. 2 Course Outcomes By the end of the course the student will demonstrate ability to: 1. -

Introduction Contents • Purpose of Teletraffic Theory • Teletraffic models • Classical model for telephone traffic • Classical model for data traffic 2 1. Introduction Traffic point of view • Telecommunication system from the traffic point of view: incoming outgoing users traffic system traffic • Ideas: – the system serves the incoming traffic – the traffic is generated by the users of the system 3 1. Introduction Interesting questions • Given the system and incoming traffic, what is the quality of service experienced by the user? • Given the incoming traffic and required quality of service, how should the system be dimensioned? • Given the system and required quality of service, what is the maximum traffic load? incoming outgoing users traffic system traffic 4 1. Introduction General purpose (1) • Determine relationships between the following three factors: – quality of service – system capacity – traffic load quality of service system capacity traffic load 5 1. Introduction General purpose (2) • System can be – a single device (e.g. a link between two telephone exchanges, a processor routing packets in a data network, a statistical multiplexer in ATM network) or – a whole communications network (e.g. telephone or data network) or a part of it • Typically a system consists of – a device (hardware) and – principles controlling it (software) • Traffic, on the other hand, consists of (depending on the case) – calls, packets, bursts, cells, etc. 6 1. Introduction General purpose (3) • Quality of service can be described – from the users point of view • e.g. call blocking probability, distribution of delay experienced by a packet stream – from the system point of view (= performance of the system) • e.g. -
