Traditional IP Measurements: What Changes in a Today Multimedia IP Network

ISP which is the main broadband telecommunication company in Italy. The network relies on a fully IP architecture and delivers to the user data, VoIP and IPTV services over a single broadband connection. The aims of this paper are the evaluation of traditional measurement indexes in a novel network environment with a mixture of traffic generated by various services and the identification of possible changes of the traffic properties due to this traffic mixture. The authors' measurement campaign, based on passive techniques, provides traffic characterization at both the packet and the connection/ flow levels and focuses on time evolution, distributions, long range dependence and periodicity properties.
