Peer-to-peer/P2P networks are the alternative to central server networks. Instead of all members feeding of a central server that responds to user requests, P2P networks use the connectivity between participants in the network to handle traffic, whereby requests are handled across the total pool of participants, each of whom contributes to the total computing power, storage space and bandwidth of the network. An important advantage is that the capacity of P2P networks increases as they add members. This is in sharp contrast to client-server networks, where additional customers will cause lower transfer speeds. For content distributors, the appeal of P2P networking is that it reduces central overheads.
