Abstract
A method may include obtaining a source file at a node in peer-to-peer network and dividing the source file into a plurality of pieces. The pieces of the source file may be encoded using network coding principles. A last-modified-date (LMD) value may be appended to each of the encoded pieces, the LMD value being the same for each of the encoded pieces of the source file. The encoded pieces with the LMD values may be sent to one or more other nodes in the peer-to-peer network.
