Overview This paper presents the experiences with a P2P content distribution system that uses Network Coding. Using results from live trials, the authors are able to present a detailed performance analysis of such P2P system from a variety of novel perspectives and show that Network Coding incurs little overhead, both in terms of CPU processing and I/O activity, and it results in smooth and fast downloads. To ensure secure transfers, the authors describe a novel scheme that verifies encoded blocks on-the-fly and analyze its performance and also study the effect of peers behind NATs and firewalls and show the robustness of the system to large number of unreachable peers.
