Availability of titles on peer-to-peer file sharing networks
File sharing, typically involving video or audio material in which copyright may persist and using peer-to-peer (P2P) networks like BitTorrent, has been reported to make up the bulk of Internet traffic (Pouwelse et al., 2008; Kryczka et al., 2011). The free-riding problem appears in this “digital gift economy” but its users exhibit rational behaviour (Becker and Clement, 2006), subject to the c...
متن کاملContent Availability, Pollution and Poisoning in Peer-to-Peer File Sharing Networks∗
Copyright holders have been investigating technological solutions to prevent distribution of copyrighted materials in peerto-peer file sharing networks. A particularly popular technique consists in “poisoning” a specific item (movie, song, or software title) by injecting a massive number of decoys into the peer-to-peer network, to reduce the availability of the targeted item. In addition to poi...
متن کاملReal Datasets for File-Sharing Peer-to-Peer Systems
The fundamental drawback of unstructured peer-to-peer (P2P) networks is the flooding-based query processing protocol that seriously limits their scalability. As a result, a significant amount of research work has focused on designing efficient search protocols that reduce the overall communication cost. What is lacking, however, is the availability of real data, regarding the exact content of u...
متن کاملModeling Peer-Peer File Sharing Systems
Peer-peer networking has recently emerged as a new paradigm for building distributed networked applications. In this paper we develop simple mathematical models to explore and illustrate fundamental performance issues of peer-peer file sharing systems. The modeling framework introduced and the corresponding solution method are flexible enough to accommodate different characteristics of such sys...
متن کاملAvailability and Popularity Measurements of Peer-to-Peer File Systems
Although peer-to-peer networking applications continue to increase in popularity, there have been few measurement studies of their performance. We present the first study of the popularity of files stored and transferred among peers in Napster and Gnutella over month-long periods. Our analysis indicates that the popularity of files is skewed in all four cases and fits well to a log-quadratic di...
