Structured peer-to-peer overlay networks provide a solution for the construction of large scale, decentralized applications, including distributed storage, group communication and content distribution. These overlays are highly flexible; they can route messages correctly even when a large numbers of the nodes crash. Network coding is beneficial technique to improve peer to peer file sharing networks. Their idea is to split the file to be distributed in fixed length blocks, later each block would be encoded and routed independently in the peer to peer network overlay. The overlay networks create a virtual topology on top of the physical topology. Because overlay networks define neighbor nodes by content stored, they can change search from a standard graph-traversal problem into a localized iterative process.
