A peer-to-peer (or P2P) computer network is a network that relies primarily on the computing power and bandwidth of the participants in the network rather than concentrating it in a relatively low number of servers. P2P networks are typically used for connecting nodes via largely ad hoc connections.
Such networks are useful for many purposes but have different impact on end users and the Enterprise. File sharing, containing audio, video, data or anything in digital format is very common as well as realtime data, such as telephony traffic, is also passed using P2P technology.

GNUnet is a secure decentralized peer-to-peer network. It boosts the ability to give the user anonymous censorship-resistent file-sharing by being implemented on top of the networking layer. All users act as routers and use link-encrypted connections to stabilize bandwidth.
