Definition

Peer-to-peer content distribution is an approach for cost-effective distribution of bandwidth-intensive content to large numbers of clients based on swarming. Content is split into blocks that are sent to different clients. Thereafter, the clients can directly exchange blocks with one another, in a peer-to-peer manner, without the help of the original server.

Historical Background

Peer-to-peer systems are application-layer networks that directly interconnect users. They have enjoyed a phenomenal success in the last 10 years together with the democratization of broadband access. The first disruptive peer-to-peer applications were designed for file sharing (e.g., Napster, Gnutella, KaZaA): they provided users with the means to (i) search for content, and (ii) distributecontent. In the research community, most of the initial focus was on structured peer-to-peer overlays, also known as distributed hash tables...
