Abstract
A method, system and computer program product for efficiently distributing video content. A peer-to-peer network and a content distribution network are used in combination to distribute video content. A content distribution network relies on servers distributed across the Internet to achieve high quality content delivery at a high cost. A peer-to-peer network distributes content among peers without incurring server side cost but may experience poor performance. The peer-to-peer network and the content distribution network are leveraged in a manner that achieves high content delivery and low cost by allowing the peer-to-peer network to serve as much content as possible while using the content distribution network to bootstrap the content in the peer-to-peer network and using it as a fallback whenever the peer-to-peer network has insufficient bandwidth, insufficient quality or when the missing piece of video content in the video buffer of the client device has an immediate deadline.
