The paper reports on a modeling and evaluation study of session characteristics of BitTorrent traffic. BitTorrent is a second generation Peer-to-Peer (P2P) application recently developed as an alternative to the classical client-server model to reduce the load burden on content servers and networks. Results are reported on measuring, modeling and analysis of application layer traces collected a...

The great efficiency achieved by the BitTorrent protocol for the distribution of large amounts of data inspired its adoption to provide multimedia content on-demand delivery over the Internet. As it is not designed for this purpose, some adjustments have been proposed in order to meet the related QoS requirements like low startup delay and smooth playback continuity. Accordingly, this paper int...

This paper presents an experimental study on the behavior of BitTorrent networks when selfish peers attempt to maintain high download rates without uploading. We modified a BitTorrent client so that it acquires a larger than normal view of a BitTorrent swarm and connects to all peers in its view. At the same time, the modified client does not upload any data to its peers. Our experimental resul...

BitTorrent is an extremely effective and popular peer-to-peer file distribution application. It differs from traditional peer-to-peer file-sharing applications in that large files are decomposed into blocks, and in order to download a file, a peer concurrently retrieves blocks from multiple peers. Measurement and simulation studies have suggested that although BitTorrent achieves excellent util...

This proceeding deals with various attacks and exploitations P2P networks have to cope with. In the last few years BitTorrent became famous for spreading big amounts of data to many people in a short time. BitTorrent will therefore be the main focus of this work. This proceeding serves basically as overview about different types of attacks. It shows attacks that are able to prevent files from b...

BitTorrent continues to comprise the largest fraction of Internet traffic. While significant progress has been made in understanding the BitTorrent choking mechanism, its security vulnerabilities have not been investigated thoroughly. This paper presents an experimental analysis of bandwidth attacks against different choking algorithms in the BitTorrent seed state. We reveal a simple exploit th...

BitTorrent, one of the most widespread used P2P application for filesharing, recently got rid of TCP by introducing an application-level congestion control protocol named uTP. The aim of this new protocol is to efficiently use the available link capacity, while minimizing its interference with the rest of user traffic (e.g., Web, VoIP and gaming) sharing the same access bottleneck. In this pape...

The strategy to send data in high speed bursts has been observed to be useful for energy-efficient communication of wireless applications. In this paper we investigate how to apply this approach to peer-to-peer (P2P) content sharing. Our main focus is on battery savings that can be achieved by properly shaping the traffic at the application level. Our primary target is BitTorrent based content ...
