Peer-to-Peer (P2P) networks enable users to directly share digital content (such as audio, video, and text files) as well as real-time data (such as telephony traffic) with other users without depending on a central server. Although originally popularized by unlicensed online music services such as Napster, P2P networking has recently emerged as a viable multimillion dollar business model for the distribution of academic and clinical information, telecommunications, and social networking. Written at an accessible level for any reader familiar with fundamental Internet protocols, Peer-to-Peer Networking and Applications explains the conceptual operations and architecture underlying basic P2P systems using well-known commercial systems as models. The book also delineates the latest research directions, thereby providing not only a sophisticated understanding of current systems, but also the means to improve upon these systems with innovations that will better performance, security, and flexibility. Peer-to-Peer Networking and Applications is thus both a valuable starting point and an important reference to those practioners employed by any of the 200 companies with approximately $400 million invested in this new and lucrative technology.

P2P Networking and Applications
Chapter One
Introduction
Our discussion of peer-to-peer (P2P) concepts starts with an overview of the key applications and their emergence as mainstream services for millions of users. The chapter then examines the relationship of P2P with the Internet and its distinctive features compared to other service architectures. A review of P2P economics, business models, social impact, and related technology trends concludes the chapter.
P2P EMERGES AS A MAINSTREAM APPLICATION
The Rise of P2P File-Sharing Applications
Nearly 10 years after the World Wide Web became available for use on the Internet, decentralized peer-to-peer file-sharing applications supplanted the server-based Napster application, which had popularized the concept of file sharing. Napster's centralized directories were its Achilles' heel because, as it was argued in court, Napster had the means, through its servers, to detect and prevent registration of copyrighted content in its service, but it failed to do so. Napster was subsequently found liable for copyright infringement, dealing a lethal blow to its business model.
As Napster was consumed in legal challenges, second-generation protocols such as Gnutella, FastTrack, and BitTorrent adopted a peer-to-peer architecture in which there is no central directory and all file searches and transfers are distributed among the corresponding peers. Other systems such as FreeNet also incorporated mechanisms for client anonymity, including routing requests indirectly through other clients and encrypting messages between peers. Meanwhile, the top labels in the music industry, which have had arguably the most s
