ABSTRACT BitTorrent is widely used as a protocol for file sharing and has gained popularity due to its scalability and performance advantages. This paper proposes a modification to the BitTorrent protocol for Peer-to-Peer communication . The proposed method has been 

Web Services' Integration into a Peer-to-Peer BitTorrent Client

ABSTRACT Nowadays, the distribution of data is becoming more and more important. This lead to the massive adoption of the Peer-to-Peer (P2P) paradigm, in which every peer in a network is able to receive and to offer data to others. This type of architecture has 

Economics of BitTorrent communities

ABSTRACT Over the years, private file-sharing communities built on the BitTorrent protocol have developed their own policies and mechanisms for motivating members to share content and contribute resources. By requiring members to maintain a minimum ratio

ABSTRACT In the area of network performance and discovery, network tomography focuses on reconstructing network properties using only end-to-end measurements at the application layer. One challenging problem in network tomography is reconstructing available 

Caching for BitTorrent-like P2P systems: a simple fluid model and its implications
free download

ABSTRACT Peer-to-peer file-sharing systems are responsible for a significant share of the traffic between Internet service providers (ISPs) in the Internet. In order to decrease their peer-to- peer-related transit traffic costs, many ISPs have deployed caches for peer-to-peer traffic 

Classification of content and users in BitTorrent by semi-supervised learning methods
free download

ABSTRACT P2P downloads still represent a large portion of today's Internet traffic. More than 100 million users operate BitTorrent and generate more than 30% of the total Internet traffic. Recently, a significant research effort has been done to develop tools for automatic 

Experimental assessment of bittorrent completion time in heterogeneous TCP/uTP swarms
free download

BitTorrent, one of the most widespread used P2P application for file-sharing, 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 

Incentives build robustness in BitTorrent

ABSTRACT The BitTorrent file distribution system uses tit-fortat as a method of seeking pareto efficiency. It achieves a higher level of robustness and resource utilization than any currently known cooperative technique. We explain what BitTorrent does, and how economic 

Modeling and performance analysis of BitTorrent-like peer-to-peer networks

ABSTRACT In this paper, we develop simple models to study the performance of BitTorrent, a second generation peer-to-peer (P2P) application. We first present a simple fluid model and study the scalability, performance and efficiency of such a file-sharing mechanism. 

The bittorrent p2p file-sharing system: Measurements and analysis
free download

Of the many P2P file-sharing prototypes in existence, BitTorrent is one of the few that has managed to attract millions of users. BitTorrent relies on other (global) components for file search, employs a moderator system to ensure the integrity of file data, and uses a 

Dissecting bittorrent: Five months in a torrent's lifetime

Popular content such as software updates is requested by a large number of users. Traditionally, to satisfy a large number of requests, lager server farms or mirroring are used, both of which are expensive. An inexpensive alternative are peer-to-peer based 

Analyzing and improving a bittorrent networks performance mechanisms

ABSTRACT In recent years, BitTorrent has emerged as a very scalable peer-to-peer file distribution mechanism. While early measurement and analytical studies have verified BitTorrent's performance, they have also raised questions about various metrics (upload 

Improving traffic locality in BitTorrent via biased neighbor selection
free download

ABSTRACT Peer-to-peer (P2P) applications such as BitTorrent ignore traffic costs at ISPs and generate a large amount of cross-ISP traffic. As a result, ISPs often throttle BitTorrent traffic to control the cost. In this paper, we examine a new approach to enhance BitTorrent traffic 

Measurements, analysis, and modeling of BitTorrent-like systems

ABSTRACT Existing studies on BitTorrent systems are single-torrent based, while more than 85% of all peers participate in multiple torrents according to our trace analysis. In addition, these studies are not sufficiently insightful and accurate even for single-torrent models, 

Do incentives build robustness in BitTorrent

ABSTRACT A fundamental problem with many peer-to-peer systems is the tendency for users to``free ride''--to consume resources without contributing to the system. The popular file distribution tool BitTorrent was explicitly designed to address this problem, using a tit-for- 

BiToS: Enhancing BitTorrent for supporting streaming applications

ABSTRACT BitTorrent (BT) in the last years has been one of the most effective mechanisms for P2P content distribution. Although BT was created for distribution of time insensitive content, in this work we try to identify what are the minimal changes needed in the BT's 

Incentives in BitTorrent induce free riding

ABSTRACT We investigate the incentive mechanism of BitTorrent, which is a peer-to-peer file distribution system. As downloaders in BitTorrent are faced with the conflict between the eagerness to download and the unwillingness to upload, we relate this problem to the 

Free riding in BitTorrent is cheap

ABSTRACT While it is well-known that BitTorrent is vulnerable to selfish behavior, this paper demonstrates that even entire files can be downloaded without reciprocating at all in BitTorrent. To this end, we present BitThief, a free riding client that never contributes any
