The Power of P2P beyond File Sharing

Peer-to-peer (P2P) model has been actively and widely used for file sharing in Internet. While many research efforts have been made to improve its performance, some organizations have expressed their serious concerns to P2P applications in Internet, such as copyright violations, information leaking, and inefficient usage of Internet resources. Instead of presenting my subjective views to these ...

Beyond Music File Sharing: A Technical Introduction to P2P Networks

Peer-to-peer systems have largely replaced the client-server architecture. There are different solutions for the arising problems of efficient object location, scalability, and robustness, resulting in different approaches. We give a short overview of the concepts of structured and unstructured peer-to-peer networks and discuss the handling of those problems in each case. In particular, the Bit...

File Sharing on Album Sales

I quantify the relationship between private–network file sharing activity and album sales in the BitTorrent era using a panel of 2,109 albums’ U.S. sales and file sharing downloads during 2008.

I find eviden...

The eDonkey 2000 file-sharing network is one of the most successful peerto-peer file-sharing applications, especially in Germany. The network itself is a hybrid peer-to-peer network with client applications running on the end-system that are connected to a distributed network of dedicated servers. In this paper we describe the eDonkey protocol and measurement results on network/transport layer ...
