Deliverable No : D . WP . JRA . 5 . 1 . 2 Methods , Techniques and Tools for IP Traffic Characterization , Measurements and Statistical Methods

The deliverable describes the “Methods, Techniques and Tools for IP Traffic Characterization, Measurementsand Statistical Methods” that members of WP.JRA.5.1 “IP Traffic Characterization, Measurements and Sta-tistical Methods” have developed during the second phase of the action EuroNGI.Main streams of the investigations on traffic measurements, statistical analysis and traffic characterization ofIP traffic and new services in evolving wired and wireless IP networks are reflected by the presented researchresults that have been selected for this report. 8Deliverable D.JRA.5.1.2.0 1 Research Achievements 1.1 Research Objectives The research activities of NoE action EuroNGI, WP.JRA.5.1 “IP Traffic Characterization, Measurements andStatistical Methods” has been divided into three working areas: • Traffic characterization of different service models and network environments• Traffic analysis, estimation and generation techniques• Architectures and tools for traffic monitoring and modeling While the first two items represent active research areas of members of the work package, the third itemreflects the integration aspects of the activity.The deliverable presents selected research results that are related to these research objectives. They arestructured according to the tasks identified in the specification “Traffic modeling for new services” of thework package. The latter represents the outcome of the preparation phase of WP.JRA.5.1. 1.2 Outline of the Document The scientific investigation of WP.JRA.5.1 has been based on the achievements of the contributing partiesduring the second phase of the action EuroNGI. It is organized according to the main topics in the statedworking areas and addresses the subsequently sketched issues. • Traffic characterization of different service models and network environments – Internet and Web traffic modelingRegarding the analysis of Internet and Web traffic the contributions have been classified into thefollowing subcategories:. Statistical inspection and analysis techniquesIn chapter 2 Markovitch and Krieger discuss the statistical methodology to analyze mea-surements arising from Internet traffic. Since the underlying traffic characteristics are oftendistributed with heavy tails. specific analysis and estimation techniques are required. In thecontribution fast and simple methods for the detection of these heavy-tailed characteristicsin traffic data are considered. Moreover, a traffic characterization by recurrent marked pointprocesses is discussed. Finally, the recommended statistical tools are applied to real Webdata.
