Purpose: In any distributed application, the communication between the distributed processes/nodes of the distributed systems is essential for both reliability and efficiency matters. In this work we address this issue for distributed applications based on JXTA protocols aiming at extending and evaluating the protocols of the JXTA library for reliable P2P computing. Approach: After a careful ex...

Peer-to-peer (P2P) networking has emerged as a promising technology that enables distributed systems to operate in decentralized manner. P2P networks are based on model where each node the network can act both client and server, thereby enabling data resource sharing without relying centralized servers. The gained considerable attention recent years due its potential provide scalable, fault-tol...

Peer-to-peer (P2P) systems have become a major area of research in the past few years. Their potential was first revealed by the hugely popular P2P file sharing applications, which allow any computer (as a peer), anywhere in a large scale distributed computing environment, to share information and resources with others. The computing environments promoted by P2P systems and technology are decen...

Peer-to-peer (P2P) technologies have been widely used for content sharing, popularly called “file-swapping” networks. This chapter gives a broad overview of content sharing P2P technologies. It starts with the fundamental concept of P2P computing followed by the analysis of network topologies used in peer-to-peer systems. Next, three milestone peer-to-peer technologies: Napster, Gnutella, and F...

P2P networks were new stars of 21 century and they were widely used in nowadays networks.It was factually an overlay network for distributed object store, search and sharing. But P2P networks frequently lacked of dependability, some peer nodes could be easily lost.So it was very important to study the architecture and frangibility of p2p networks and know the characteristics when nodes invalida...

Many emerging applications that use XML are distributed, usually over large peer-to-peer (P2P) networks on the Internet. The deployment of an XML query shipping system over P2P networks requires a specialized synopsis to capture XML data in routing tables. In this paper, we propose a novel graph-structured routing synopsis, called kd-synopsis, for deployment over unstructured super-peer based P...

P2P file sharing system is one of the hot research topics. However, most of such systems do not support auto extraction of metadata and provide only searches via resource titles. Combining the Chord algorithm and the SHA algorithm, this paper proposed a new P2P search model based on Distributed Hash Table (DHT). The procedures of establishing such P2P networks are presented. The design and impl...

We are experiencing a revolution in the wireless technology and mobile phone networks as they are becoming increasingly ubiquitous. On the other hand, there is another trend, gaining extreme popularity over the traditional wired Internet: Peer-to-Peer (P2P) networking. Specifically, Distributed Hash Table (DHT) based Structured P2P overlay networks are capable to facilitate information storage ...

Peer-to-Peer overlay systems offer a substrate for the construction of large scale and distributed applications. The Peer-to-Peer technique is differentiated in to two major forms, Structured P2P and Unstructured P2P. In structured peer-to-peer networks, connections in the overlay are fixed. They typically use distributed hash table-based (DHT) indexing, such as in the Chord system. Unstructure...
