To measure the impact of Network Coding on classical P2P systems, we have designed and added a Network Coding module in an existing P2P-VoD system called PPlayer. As we worked in a micro environment we got more focused on the influence of Network Coding on individual peer rather than on the overall system throughput. However, the tests performed in our laboratory have highlighted some advantages. With equal performances, less data are sent on the network and slow peers can help to provide data. But Network Coding implies a heavy computing complexity which is an obstacle in the deployment of Network Coding at a large scale. To deal with it we propose two solutions: the generation of half decoded blocks and a buffering system allowing a peer to provide more peer at the same time.
