PURPOSE: A system for peer-to-peer communications excellently configured among network devices communicating via a common bus, and a network device and method are provided to allow peer-to-peer communications in a network more effectively than an existing network system. CONSTITUTION: A bus controller(12) is positioned at telecommunication which can transmits a command to a network bus(14), controls communication in the network bus(14) and has the network bus(14). Network devices(16,18,20) include a set of the first and second data channels and are positioned at the telecommunication. The first data channel is formed for a surrogate operation by including a start command and a surrogate command. When the bus controller(12) transmits a command to the network bus(14) matched to the start command of the first data channel, the second data channel executes the start command and the first data channel continuously executes each surrogate command, and thus, peer-to-peer communication can be made between the first and second data channels.
