Peer-to-peer networking, a disruptive technology for large scale distributed applications, has gained widespread attention due to the successes of peer-to-peer (P2P) content sharing, media streaming, and telephony applications. In addition, a large range of new applications are under development or being proposed. The underlying architectures share features including decentralization, end system resources, autonomy, virtualization, and self-organization. These features constitute the P2P paradigm. Trends in information and network technology such as increased performance and deployment of broadband networking, wireless networking, and mobile devices are synergistic with and reinforce the capabilities of this P2P paradigm.

"The Handbook of Peer-to-Peer Networking is a comprehensive and unified repository of the various models, applications, methodologies, trends, and challenges of peer-to-peer computing, making it an essential reference for researchers and proffesionals alike. This handbook addresses current issues as well as emerging concepts and applications, including P2P architectures, search and queries, incentive mechanism, multimedia streaming, service- oriented architectures, collaboration to share non-storage resources, mobile P2P, theory and analysis, and P2P databases. In addition, it covers practical perspectives such as traffic characteristics and trends of P2P applications, and E-business models in P2P applications."
