ABSTRACT:
A method of distributing a data item to a plurality of computers in a network of computers. A data item is divided into a plurality of segments. Each segment is stored on at least one computer in said network. A list of computers onto which each of said segments has been stored is maintained. When a data item is requested, its component segments are obtained from at least two computers in the network. Some of the computers may form a peer-to-peer network.
