Abstracts: Information and communication technologies (ICT) have an increasing influence on the daily life of citizens. In particular, the internet is creating a new layer of participation of individuals in the societal and economic life. Activities that have been performed offline are now offered as online services on the internet. Internet usage has changed, and the demands on the broadband access networks have increased, both regarding bandwidth and Quality of Service. Characterizing the traffic, as seen by a broadband access network, can help understanding both the demands of today and the demands of tomorrow. As the web evolves, Internet usage patterns change heavily. For the simulation and development of new protocols and routing algorithms, it is important to have accurate and up-to-date Internet traffic models that describe the user behaviour and network usage. For network administrators, it is crucial to have knowledge of what is happening in their network. Additionally, consecutive measurements help to identify bottlenecks, network misconfiguration, and its misuse. In this project we will analyse traffic measurements from a broadband access network and derive corresponding user behaviour models. Our application classification reveals a trend back to HTTP traffic, underlines the immense usage of flash videos. The project focuses on Internet usage in terms of traffic patterns, volumes and applications. Also, user activity, its characteristics, session lengths and traffic rate distributions, will be analysed.
