Peer-to-peer (P2P) is a distributed application architecture that partitions tasks or workloads between peers. Peers make a portion of their resources, such as processing power, disk storage or network bandwidth, directly available to other network participants, without the need for central coordination by servers or stable hosts. This is in contrast to the traditional client-server model.
Clients and servers for various peer-to-peer protocols are available in Debian. The list includes:
BitTorrent - peer-to-peer file sharing protocol used for distributing large amounts of data
GNUnet - peer-to-peer framework which focuses on providing security
aMule - client for the eD2k and kademlia networks
mldonkey-gui - Peer-to-peer file sharing client that supports multiple protocols
nicotine - client for the SoulSeek network
