It is increasingly necessary to identify and successfully characterize peer-to-peer (P2P) traffic as it predominates in the Internet. Yet there is however no proven methodology to achieve this as it often hides itself behind well-known services and does not maintain fixed port numbers. This work analyses P2P traffic by examining packet load in the Brazilian academic network (RNP) and a commercial service provider (ISP). The obtained results show that P2P corresponds up to 60% of the total PoP-PE traffic and up to 40% in the ISP. Furthermore, this traffic has resulted in a significant change in profile in that it increased its outbound traffic to almost the level of inbound traffic.
