ABSTRACT
BitTorrent and Practical Network Coding are efficient methods for sharing files in a peer-to-peer network. Both face the problem to distribute a given file using peers with different and dynamic bandwidth and only temporal availability. For this, BitTorrent partitions the files and uses the upload and download of each peer. In addition to this, Practical Network Coding uses a random linear combination of the parts. The original file can be decoded by a matrix operation as soon as enough linear combinations have been gathered at a peer.
