A method of generating an IEEE 1394 virtual network in which a virtual network is constructed on the IEEE 1394 network and respective nodes sense the virtual network and a controller for generating the virtual network. The method steps of connecting a virtual network controller for generating a virtual self ID packet including a virtual node ID information required for constructing a virtual network to a predetermined IEEE 1394 network, the respective nodes and the virtual network controller constructing the IEEE 1394 network for determining whether they are branches or leaves by performing virtual bus initialization, determining parent ports and child ports with respect to the ports of the respective nodes and a root node by performing a virtual tree identification, and determining the physical node IDs of the respective nodes by sending the prepared virtual self ID packet.
