Abstract
A peer-to-peer live content delivery system and method enables peer-to-peer sharing of live content such as, for example, streaming video or audio. Nodes receive broadcasts of available data from neighboring nodes and determine which data blocks to request. Nodes receiving requests for data determine whether or not to accept the requests and provide the requested blocks when accepted. To enable sharing of live content, sharing of data blocks is constrained such that a node attempts to receive a particular data block prior to a playback deadline for the data block. This allows a node continuously provide an output stream of the received data such as, for example, an output of live video content to a display.
