ABSTRACT:
A network device includes a network protocol controller and a device controller. The device controller controls a plurality of service devices including a first device, and a second device of different type from the first device. The network protocol controller and the device controller are connected by a packetized logical channel for the first device. The network protocol controller, upon having received a message in the network plug-and-play protocol and destined for the second device, transfers the content of the message body of the received message to the device controller, using the logical channel for the first device.
