ABSTRACT:
A method and system allows any peer to efficiently distribute content to all other peers in a peer group using existing propagation mechanisms. According to the invention, binary contents are broadcast over existing propagation mechanisms such as propagation pipes using a generic capability that can be used by any application that wants to multicast binary contents. According to the invention, the binary contents are broken up into file blocks that are then sent over existing propagation mechanisms such as propagation pipes. According to the present invention, the receiving peers negotiate among themselves to make up any file blocks they may have missed from the original broadcast. When each peer has all the file blocks associated with a given parent file, they store the content.
