  Broadband Traffic Measurement and Analysis (BTMA) Phase II, Descrição: Based on the growing interest of application identification within ISPs networks the research community has been developing valuable techniques in order to achieve high precision level without breaking rules (e.g., looking at packet payloads) or having scalability problems. As an unresolved issue, application identification by relying on either flow records or packet headers has attracted many researchers from different fields. Furthermore, the current trend of moving phone calls from the PSTN to the Internet via VoIP P2P applications induces an open avenue for research since its effects have not been completely understood. Along with VoIP P2P applications, two types of applications have been recently gaining a lot of attention of the network community. With the widespread deployment of broadband access technologies, the increase of the number simultaneous online users of Massively Multiplayer Online Games (MMOG) and Networked Virtual Environments (NVE) is putting pressure on both MMOG/NVE servers and ISPs network infrastructure and demanding an in-depth traffic analysis of their network behavior. On the top of that, Video P2P Apllications (e.g., Joost, PPLive, GridMedia, TVU Player/Broadcast) and popular video streaming websites (e.g., YouTube, SoapBox) are also demanding a precise characterization of the performance on the underlying network. In this project proposal, we envisage to deeply investigate the traffic behavior taking into account the raise of such new applications and its correlation with the user profile. We will also be able to undertake performance analysis of recent inference algorithms that rely on both packet and flow information... , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (2) / Doutorado: (2) . , Integrantes: Thiago de Barros Lacerda - Integrante / Djamel Fawzi Hadj Sadok - Coordenador / Stênio Flávio de Lacerda Fernandes - Integrante / Arthur de Castro Callado - Integrante / Rafael Thyago Antonello - Integrante / Alysson Feitoza Santos - Integrante.

  BTMA - Broadband Traffic Measurement and Analysis, Descrição: Broadband Traffic Measurement and Analysis Characterization of Internet traffic has become over the past few years one of the major challenging issues in telecommunications networks. The availability of broadband connections for Internet users has been increasingly growing, particularly based on cable TV and ADSL technologies so that new possibilities for resource usage has been emerging, by users from small organizations and home users. The increased capacity and availability provided by the broadband connection lead to a complex behavior of a typical user, potentially very different from a dial-up user. Consequently the traffic mix generated by such users is different from typical dial-up users, as well as from commercial users. There have been some efforts on measuring and analyzing broadband traffic, on most of them point out that currently the predominant type of traffic is produced by the so-called Peer-to-Peer (P2P) file sharing applications, such as KaZaA, eDonkey and BitTorrent. Depending on the location, hour or day, the P2P traffic is responsible for 40% to 80% of the total traffic volume. However, those previous investigations suffer from known limitations, such as loss of information due to traffic summarizations, failure to correctly identify the application and little comprehension of the user behavior. Furthermore, the current trend of moving phone calls from the PSTN to the Internet via VoIP P2P applications represents a thereat to telephony companies and its effects have not been completely understood. This project is aimed at building a real infrastructure within an ISP for measuring, storing, filtering, making relations and analyzing broadband traffic. One of its main achievements will be the development of a software tool, which incorporates statistic techniques, able to provide meaningful information for both technical and management staff of an ISP, software and hardware vendors and to the Internet scientific community... , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (1) / Mestrado acadêmico: (1) / Doutorado: (2) . , Integrantes: Thiago de Barros Lacerda - Integrante / Djamel Fawzi Hadj Sadok - Coordenador / Stênio Flávio de Lacerda Fernandes - Integrante / Arthur de Castro Callado - Integrante / Rafael Thyago Antonello - Integrante / Josilene Aires Moreira - Integrante.
