We study the performance of a VoIP call in an IPv6 network during download of a large file using HTTP, BitTorrent, or uTP, and simultaneous downloads using HTTP and BitTorrent or HTTP and uTP. Performance metrics include maximum delta, maximum and mean jitter, throughput, packet loss, and perceived voice quality. The results indicate that the values of these metrics are stable and that call qua...

BitTorrent is currently the dominant Peer-to-Peer (P2P) protocol for file-sharing applications. BitTorrent is also a nightmare for ISPs due to its network agnostic nature, which is responsible for high network transit costs. The research community has deployed a number of strategies for BitTorrent traffic localization, mostly relying on the communication between the peers and a central server c...

A BitTorrent community is a peer-to-peer (P2P) computer network. All users have restricted upload and download bandwidths, and they have different seed libraries, while various objectives could emerge in the network. The behavior of the peers is determined by the BitTorrent protocol which was designed originally for file exchange. However, other applications are also possible as BitTorrent Assi...

Real-world measurements play an important role in understanding the characteristics and in improving the operation of BitTorrent, which is currently a popular Internet application. Much like measuring the Internet, the complexity and scale of the BitTorrent network make a single, complete measurement impractical. While a large number of measurements have already employed diverse sampling techni...

BitTorrent is a new popular application layer network protocol used to distribute files. BitTorrent is efficient at content delivery by maximizing the upload utilization and by preventing unfairness. This paper discusses the BitTorrent architecture and protocol in great detail by discussing the tracker and all the messages sent between the peers and the tracker and also between peers and peers....

BitTorrent piracy is at the core of fierce debates around network neutrality. Most of the legal actions against BitTorrent exchanges are targeted toward torrent indexing sites and trackers. Surprisingly, little is known about the initial seeds that insert contents on BitTorrent and about the highly active peers that are present in a large number of torrents. The main reason is that acquiring th...

BitTorrent is arguably the most popular media file distribution protocol used in Internet today. Even though empirically BitTorrent seems to be both efficient and scalable, there has been very little research on the detailed dynamics of its built-in control mechanisms, and their effectiveness across a wide variety of network configurations and protocol parameters. The main goal of this paper is...
