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.
Claims9
A network plug-and-play compliant network device, comprising:
- a device unit including one or more service devices for executing a service in response to a request from a client on a network;
- and
- a network protocol controller configured to receive a message destined for the service devices from a client on the network, and to transfer the message to the device unit,
- wherein the device unit holds a device description defining a configuration of each service device according to a network plug-and-play protocol architecture,
- the network protocol controller, 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,
- the total device description describes that the network device has the device configuration in accordance with the network plug-and-play architecture wherein the device configuration is a nested configuration having the one or more service devices included within a single basic device representing the network device.
A method of controlling a network plug-and-play compliant network device, the network device comprising a device unit including one or more service devices for executing a service in response to a request from a client on a network, and a network protocol controller configured to receive a message destined for the service devices from a client on the network and to transfer the message to the device unit, the method comprising the steps of:
- (a) providing a device unit which holds a device description defining a configuration of each service device according to a network plug-and-play protocol architecture;
- and
- (b) obtaining the device description of the service devices from the device unit responsive to startup or connection of the network protocol controller and the device unit, and creating a total device description defining a device configuration of the entire network device,
- wherein the total device description describes that the network device has the device configuration in accordance with the network plug-and-play architecture wherein the device configuration is a nested configuration having the one or more service devices included within a single basic device representing the network device
A network protocol controller for use in a network plug-and-play compliant network device, the network device comprising a device unit including one or more service devices for executing a service in response to a request from a client on a network,
- wherein the device unit holds a device description defining a configuration of each service device according to a network plug-and-play protocol architecture,
- the network protocol controller, 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,
- the total device description describes that the network device has the device configuration in accordance with the network plug-and-play architecture wherein the device configuration is a nested configuration having the one or more service devices included within a single basic device representing the network device
