An as-level approach to network traffic analysis and modelling
Résumé
The exponential growth of internet traffic over the last twenty years presents a real challenge to ISP looking to ensure a reliable and efficient service to their customers. Network traffic is far from being straightforward to predict and a deep understanding of the routing domains is a first requirement to achieve proper management of the traffic. This paper focuses on the monitoring and characterisation of traffic for a European Tier-2 operator (Post Luxembourg). It aims, at first, to provide a thorough analysis of the traffic passing through the network using a Netflow collection process. Secondly, it provides a first approach to model the AS-level traffic using a time-series analysis approach.
