Peer-to-peer communication is emerging as one of the most potentially disruptive technologies in the networking sector. If the interest in such technologies as Napster, Morpheus and Gnutella is any indication, peer-to-peer networks will be a major component in the future of computer communications and the Internet. In this work, we conducted a case study by implementing the Xiangqi game using a...

Distributed computing systems allow acquiring resources that lie outside the capabilities of even the largest supercomputers. Indisputable example is prosperity of SETI@Home project which gathered at its peak ca. 850,000 users. Its success is partially related to well designed architecture – BOINC. Many projects work on this architecture, using all together the computing power of ca. 400 TeraFL...

Resource search or discovery is a fundamental issue in peer-to-peer (P2P) and grid studies.1 Search objects, or resources, can be cycles, storage spaces, files, services, addresses, and so on. In general, systems are employing three categories of P2P-network architectures to improve search performance: centralized (such as Napster, http://www.napster.com/), decentralized but structured (such as...

The community of peer-to-peer (P2P) file-sharing networks has been expanding swiftly since the appearance of the very first P2P application (Napster) in 2001. These networks are famous for their excellent file transfer rates and adversely, the flooding of copyright-infringed digital materials. Recently, a number of documents containing personal data or sensitive information have been shared in ...

Developing algorithms suitable for distributed environments is important as data becomes more distributed. This paper proposes a distributed KMedian clustering algorithm for use in a distributed environment with centralized server, such as the Napster model in a peer-to-peer environment. Several approximate methods for computing the median in a distributed environment are proposed and analyzed ...

Peer-to-peer (p2p) systems are a fairly recent class of distributed systems. Early systems, such as Napster and SETI@Home, rely on a central server, while more recent systems like Gnutella and FastTrack are decentralized. One can also include “server peer-to-peer” systems, including USENET, MixMaster remailers and internet routing. As is common with new technologies, practice is significantly a...

The limitations of client/server systems become evident in an Internet-scale distributed environment. Peer-topeer (P2P) systems offer an interesting alternative to traditional client/server systems: Every node acts both as a client and a server and “pays” its participation by providing access to its computing resources. Systems such as Napster and Gnutella have proven their practical applicabil...

The entertainment industry has obsessed over the threat of peer-to-peer file sharing since the introduction of Napster in 1999. The sharing of television content may present a compelling case for fair use under the long-standing “Betamax” decision. Some argue that television sharing is fundamentally different than the distribution of music or movies since television is often distributed for fre...

From the recent improvements in network and peer-to-peer technologies and the ever-growing needs for computer might, new ways of sharing resources between users have emerged. These methods are very diverse, from SETI@HOME which is a way to share the load of analysing the data from space in order to find traces of extraterrestrial life, to NAPSTER and its successors, and to Real-time video-games...
