Using Network Coding Make P2P Content Sharing Scalable

The usual network message transmission is based on store and forward mechanism.The network node does not process the network messages.Network coding theory has changed this routing form. Toimprove the network transmission capacity,it allows nodes to encode the transmitting messages.Some researches show that the network coding theory makes the node reach the maximal network traffic introduced by max flow min cut theory.Our paper uses network coding theory to optimize the performance of P2P network resource sharing.Lastly,we implement a P2P content sharing system based on network coding and design simulations to evaluate its performance. Analysing the experimental results,we find that network coding theory make P2P content sharing application efficient and scalable.
