Abstract: When the network protocol controller 302 of the network device 200 receives a message sent from a client, it interprets the message header in accordance with network plug-and-play protocol without interpreting the content of the message body; and sends the message body to the device controller 402 in accordance with another communication protocol. The device controller 402 interprets the content of the message body and causes the service devices 404, 406 to execute service.

Abstract: Disclosed herein is a printing device connected to a client, the printing device including: a reception unit which receives plural types of logic packets from the client; a hardware packet processing unit which processes the logic packets by hardware; a software packet processing unit which includes a microprocessor and processes the logic packets by software; and a sorting unit which sorts the plural types of logic packets into a logic packet to be processed by the hardware packet processing unit and a logic packet to be processed by the software packet processing unit, wherein the sorting unit sorts a reply requiring logic packet including contents replying to the client as the logic packet to be processed by the hardware packet processing unit when sorting the plural types of logic packets.

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.

Abstract: The network device 200 includes the device unit 400 having service devices 404, 406 to execute a service, and the network protocol controller 302. The device unit 400 holds a device description defining a configuration of each service device according to the network plug-and-play protocol architecture. The network protocol controller 302, responsive to startup or connection of the network protocol controller and the device unit, obtains the device description of the service devices from the device unit, and creates a total device description defining a device configuration of the entire network device.
