O.P. Undecided  Microsoft to create peer-to-peer better than BitTorrent.
A whitepaper released today by Microsoft proposes a new, network encoding based, peer-to-peer technology in which each part of the file is encoded with information about other pieces. They say that this allows the reconstruction of the file being downloaded quicker and without slowdowns towards the end such as the case in torrents. They also say that it will allow the file to be downloaded 20-30% faster than of the, server encoded only BitTorrent type.
Here is the main quote:


We propose a new scheme for content distribution of large files that is based on network coding. With network coding, each node of the distribution network is able to generate and transmit encoded blocks of information. The randomization introduced by the coding process eases the scheduling of block propagation, and, thus, makes the distribution more efficient. This is particularly important in large unstructured overlay networks, where the nodes need to make block forwarding decisions based on local information only. We compare network coding to other schemes that transmit unencoded information (i.e. blocks of the original file) and, also, to schemes in which only the source is allowed to generate and transmit encoded packets. We study the performance of network coding in heterogeneous networks with dynamic node arrival and departure patterns, clustered topologies, and when incentive mechanisms to discourage free-riding are in place. We demonstrate through simulations of scenarios of practical interest that the expected file download time improves by more than 20-30% with network coding compared to coding at the server only and, by more than 2-3 times compared to sending unencoded information. Moreover, we show that network coding improves the robustness of the system and is able to smoothly handle extreme situations where the server and nodes leave the system.
