In this paper, we study the impact of network latency on the time required to download a file distributed using BitTorrent. This study is essential to understand if testbeds can be used for experimental evaluation of BitTorrent. We observe that the network latency has a marginal impact on the time required to download a file; hence, BitTorrent experiments can performed on testbeds.

BitTorrent is a P2P file distribution system designed for distributing large files. The current mechanism used to implement BitTorrent does not support streaming of data but with few changes in the protocols of BitTorrent this system can also be used for streaming data. Two important mechanisms which we have to consider while making changes are BT’s Piece selection mechanism and Incentive mecha...

Peer-to-Peer file sharing generates by far the most Internet traffic reaching up to 70 % in some regions of the world. These data volumes pose a significant challenge to Internet Service Providers regarding traffic engineering. Because Peer-to-Peer routing is usually agnostic of the underlying topology, traffic engineering abilities of Internet Service Providers are inhibited and their core net...

Message Stream Encryption (MSE) provides obfuscation, data confidentiality, and limited authentication to BitTorrent clients. Although obfuscation of header and payload data was the main design goal of MSE, users understandably still expect data confidentiality and authentication from their BitTorrent clients. In this paper, we present numerous attacks on the MSE protocol itself, independent of...

BitTorrent is undoubtedly the most popular P2P file sharing systems in existence that has been able to attract millions of users. BitTorrent depends on global components for file search, engages a moderator system to guarantee the data integrity of file, and uses an exchange mechanism for file sharing in order to discourage users from free-riding. We conduct one of the largest measurement and a...

Peer-to-Peer protocols currently form the most heavily used protocol class in the Internet, with BitTorrent, the most popular protocol for content distribution, as its flagship. A high number of studies and investigations have been undertaken to measure, analyse and improve the inner workings of the BitTorrent protocol. Approaches such as tracker message analysis, network probing and packet sni...

In this paper, we propose a hierarchical architecture for grouping peers into clusters in a large-scale BitTorrent-like underlying overlay network in such a way that clusters are evenly distributed and that the peers within are relatively close together. We achieve this by constructing the CBT (Clustered BitTorrent) system with two novel algorithms: a peer joining algorithm and a super-peer sel...

BitTorrent is undoubtedly the most popular P2P file sharing application on today’s Internet. The widespread popularity of BitTorrent has attracted a great deal of attention from networking researchers who conducted various performance studies on it. This paper presents a comprehensive survey of analytical performance modeling techniques for BitTorrent networks. The performance models examined i...

The BitTorrent Sync client application is the most progressive development in the BitTorrent family. Nevertheless, it can be used for the activities that draw the attention of the forensics invetigators. The BitTorrent Sync client application employs quite largely the encryption for sending data packages. The initiation of the activity is carried out in the plain text only. Therefore, we propos...

BitTorrent is currently one of the most popular peer-to-peer systems. BitTorrent clients are widely spread all over the world and account for a large fraction of today’s Internet traffic. In this paper, we show that BitTorrent can be exploited by misdirecting clients to send their traffic toward any host on the Internet. The volume of a BitTorrent swarm can thus be converted into firepower for ...
