Based on network coding,intermediate nodes between the source and the receiver(s) of a communication on the Internet encode incoming messages to produce coded outgoing ones.The original messages were decoded at receivers.A lot of theoretical results show that network coding is beneficial for the whole network's throughput and robustness.To evaluate the benefit of network coding for P2P(peer-to-peer)content distribution,a content distribution system based on sparse linear coding was implemented for P2P networks.Experimental results show that network coding outperforms non-coding in terms of average downloading time at peers,total distribution time and the whole throughput.
