Free riding on Gnutella

Eytan Adar, Bernardo A. Huberman
2000 First Monday  
By sampling messages on the Gnutella network over a 24-hour period, we established that nearly 70% of Gnutella users share no files, and nearly 50% of all responses are returned by the top 1% of sharing  ...  An extensive analysis of user traffic on Gnutella shows a significant amount of free riding in the system.  ...  Acknowledgments The authors would like to thank Rajan Lukose, Lada Adamic, Ed Chi, and Pam Schraedley for valuable discussions. We also thank Sara Dubowsky for her late night editorial help.  ...

Analyzing the Characteristics of Gnutella Overlays

Yong Wang, Xiaochun Yun, Yifei Li
2007 Fourth International Conference on Information Technology (ITNG'07)  
The properties of degree-rank distribution and frequency-degree distributions of the measured topology graphs are analyzed in detail.  ...  Mapping and analyzing the topological properties of P2P overlay network will benefit the further design and development of the P2P networks.  ...  These analyzing methods could help to understand the topological characteristics of Gnutella in detail, which has been an open problem in P2P network modeling and measurements.  ...

The Darknet and the Future of Content Protection [chapter]

Peter Biddle, Paul England, Marcus Peinado, Bryan Willman
2003 Lecture Notes in Computer Science  
In this paper we categorize and analyze existing and future darknets, from both the technical and legal perspectives.  ...  In view of this hypothesis, we examine the relevance of content protection and content distribution architectures.  ...  Recent measurements of libraries shared by gnutella peers indicate that the majority of content is provided by a tiny fraction of the hosts [1] .  ...

The Economics of Peer-to-Peer Networks

Ramayya Krishnan, Michael D. Smith, Rahul Telang
2003 Social Science Research Network  
We show that while the characteristics of services provided over P2P networks are similar to public goods and club goods, they have many important differences and hence there is a need for new theoretical  ...  Many new networks are being established and thousands of users are part of such P2P networks. In this chapter, we outline some important economic characteristics of these networks.  ...  For example, Adar and Huberman (2000) find that 70% of peers on the Gnutella network do not provide songs and that the top 1% of sharing hosts return 50% of all responses.  ...

2006 Lecture Notes in Computer Science  
As a developing P2P system, Gnutella has upgraded its protocol to 0.6, which significantly changed the characteristics of its hosts.  ...  Our measurements show that the assumption that query arrival follows Poisson distribution may not be true in Gnutella and most peers incline to share files of very limited types, even when MP3 files are  ...  We are also in the process of building file spreading models for Gnutella.  ...
