The subject application is directed generally to configuration of network services in networked devices. The subject application is particularly applicable to configuration of network services associated with document processing devices.
Conventional document processing services include printers, copiers, facsimile machines, and scanners. More recently, multifunction peripherals (MFPs) have evolved to perform more than one of these document processing function.
Due to the cost of purchasing and supporting document processing devices, most offices will share them among two or more users. More recently, document processing services are accessible to users via network connections, allowing users to initiate print, fax, scan, or copy operations from one or more networked computers. The many functions that may be supported by network operation, as well as the many different data communication protocols associated with networks, cause setup and configuration of network stacks of a device difficult to configure or maintain.
It is frequently incumbent upon developers to develop complex network interfaces to allow for implementation of desired network devices or services. This operation requires much development time, as well as time for testing and debugging. Additionally, use of multiple or varied network communication interfaces increases chances for conflicts or other incompatibilities.

The system further comprises communication means adapted for commencing network services in accordance with an output of the registration means and means adapted for communicating configuration file data corresponding to commenced network services with an associated data storage.
In one embodiment of the subject application, the system also includes testing means adapted for testing operation of commenced network services and means adapted for selectively restarting network services in accordance with configuration file data retrieved from the data storage in accordance with an output of the testing means. Preferably, retrieved configuration file data is comprised of configuration file data associated with a last-known successfully commenced network services.

It is to be appreciated however, that the network interface subsystem suitably utilizes any physical or non-physical data transfer layer or protocol layer as will be appreciated by one of ordinary skill in the art. In the illustration, the network interface 214 is interconnected for data interchange via a physical network 220, suitably comprised of a local area network, wide area network, or a combination thereof.
Data communication between the processor 202, read only memory 204, random access memory 206, storage interface 208 and the network interface subsystem 210 is suitably accomplished via a bus data transfer mechanism, such as illustrated by bus 212.
Also in data communication with bus the 212 is a document processor interface 222.

Such operations include copying accomplished via copy hardware 224, scanning accomplished via scan hardware 226, printing accomplished via print hardware 228, and facsimile communication accomplished via facsimile hardware 230. It is to be appreciated that the controller 200 suitably operates any or all of the aforementioned document processing operations. Systems accomplishing more than one document processing operation are commonly referred to as multifunction peripherals or multifunction devices.
Functionality of the subject system 100 is accomplished on a suitable document processing device, such as the document processing device 104, which includes the controller 200 of
In the preferred embodiment, the engine 302 allows for printing operations, copy operations, facsimile operations and scanning operations. This functionality is frequently associated with multi-function peripherals, which have become a document processing peripheral of choice in the industry. It will be appreciated, however, that the subject controller does not have to have all such capabilities. Controllers are also advantageously employed in dedicated or more limited purposes document processing devices that are subset of the document processing operations listed above.
The engine 302 is suitably interfaced to a user interface panel 310, which panel allows for a user or administrator to access functionality controlled by the engine 302. Access is suitably enabled via an interface local to the controller, or remotely via a remote thin or thick client.
The engine 302 is in data communication with the print function 304, facsimile function 306, and scan function 308. These functions facilitate the actual operation of printing, facsimile transmission and reception, and document scanning for use in securing document images for copying or generating electronic versions.
A job queue 312 is suitably in data communication with the print function 304, facsimile function 306, and scan function 308.

As shown in
In operation, common network communication features associated with each of a plurality of network stacks are first mapped via a network interface stack. A network stack is then sensed in association with an installed network communication component. Features associated with the sensed component are then mapped in accordance with the mapping of the plurality of common network communication features. Network services are then commenced based upon the output of the mapping of the features associated with the sensed network communication component. Configuration file data is then communicated to an associated data storage corresponding to commenced network services.
In accordance with one example embodiment of the subject application, a network service manager component 414 is first initiated on the controller 108 associated with the document processing device 104. Preferably, the network service manager component 414 is any software, hardware, or suitable combination thereof, which uses network management objects to manage and configure network components via pre-defined network service management and configuration interfaces. Upon the receipt of a new network stack component 406 or 408, the controller 108, via operations of the network service manager 414, determines whether the component 406 or 408 corresponds to a predefined network stack. Mapping data associated with the mapping of the predefined network stack component is then received by the controller 108 when the network stack component 406 or 408 is a predefined network stack. When the network stack component 406 or 408 is not a predefined network stack, a determination is made whether the received data, inclusive of the new stack component 406 or 408, includes a network management object 412. That is, when the component 406 is received, no new network management object 412 is received, but when the component 408 is received, a new network management object 412 is also received. As will be understood by those skilled in the art, a network management object is a library provided by network stacks, which provide the implementation of pre-defined network service management and configuration interfaces. In accordance with one embodiment of the subject application, the controller 108 employs a generic network management object 410 that functions to provide base register, unregister, status monitoring, start and stop features, enabling and disabling features, simple configuration format mapping, and the like, to the document processing device 104.
When it is determined that a new network management object 412 was not included in the received network stack component, e.g., component 406, the new stack component 406 is associated with a generic network management object 410 in association with the network service manager 414 of the controller 108. When the received network stack component, e.g., component 408, includes a corresponding network management object 412, the new network management object 412 is added to the network management objects 410 and 412 available to the network service manager 414 operative on the controller 108.
Thereafter, common network communication features are mapped via the network interface stacks 404. That is, common network communication features are mapped using the network management object 410 or 412 associated with the new network stack component 406 or 408 by the network service manager 414. A network stack 404 associated with an installed network communication component is then sensed by the network service manager 412 of the controller 108. Any sensed communication components associated with a predefined network stack component are registered with the network service manager 414. Features associated with sensed components are then mapped to common network communication features. Thereafter, network services are commenced in accordance with the mapped features associated with the sensed network communication component. Configuration file data 418 corresponding to the commenced network services is then communicated to an associated data storage 110.
The network service manager 414 then tests the operation of the commenced network service so as to determine whether the service has been successfully initiated. When the service was unsuccessfully started, configuration file data 418 corresponding to a last known good configuration is retrieved from the associated data storage device 110. Network services are then selectively restarted according to the retrieved configuration file data 418. Once a service has been successfully initiated, normal operations of the document processing device 104 are commenced until alteration data is received. That is, the document processing device 104 performs normal operations until an administrator, via a thin client interface, communicates alteration data to the document processing device 104. Upon receipt of the alteration data, the configuration file data 418 is modified to incorporate the changes received from the administrator. Network services are then selectively restarted in accordance with the changes to the configuration file data 418 and upon successful restart, normal operations of the document processing device 104 are commenced.
For example, when the document processing device 104 receives a new network stack component, for example an AppleTalk network stack, the network service manager first determines whether this is a predefined network stack. When such is not the case, a determination is made whether a network management object associated with the AppleTalk network stack has been received. When no such object was received with the AppleTalk network stack, the network service manager associates the AppleTalk network stack with the generic network management object. Common network communication features associated with the AppleTalk network stack are then mapped via the network interface stack associated with the generic management object. Detected network stacks, e.g., the AppleTalk network stack, associated with installed network communication components are mapped to common network communication features. That is, the network service manager maps various communication features, common to a plurality of different network stacks, to the AppleTalk stack, thereby improving communications available to clients using the AppleTalk network stack for operations with the document processing device 104. The mapping is then stored in an XML configuration file on the data storage device 104. When needed, the network service manager initiates a system restart to initiate the installed service, e.g., AppleTalk. When problems are detected, an administrator is able to modify the configuration file, via a thin client interface on the user device 114, to correct the error. Alternatively, the network service manager is capable of retrieving the configuration file from the storage device 110 corresponding to the last known operable configuration (good configuration) and restarting the system in accordance with that retrieved configuration file.
The skilled artisan will appreciate that the subject system 100 and components described above with respect to
A network stack is then sensed at step 504 in association with an installed network communication component. Suitable examples of network stacks 404 include, without limitation, LPD, SMB, IPP, AppleTalk, IPX, and the like. At step 506, features associated with the sensed component are then mapped in accordance with the mapping of the plurality of common network communication features. Network services are then commenced at step 508 based upon the output of the mapping of the features associated with the sensed network communication component. At step 510, configuration file data 418 corresponding to commenced network services, is then communicated to an associated data storage. In accordance with one embodiment of the subject application, the configuration file data 418 is embodied in an extensible markup language (XML) document.
Referring now to
Upon a determination at step 606 that the received component 406 or 408 does not correspond to a predefined network stack, flow progresses directly to step 610, whereupon a determination is made whether a network management object 410 or 412, was received in association with the received network stack component 406 or 408. As stated above, network management objects 410 and 412 correspond to libraries provided by network stacks, which provide implementations of predefined network service management and configuration interfaces. Preferably, the controller 108 employs a generic network management object 410 that functions to provide base register, unregister, status monitoring, start and stop features, enabling and disabling features, simple configuration format mapping, and the like, to the document processing device 104.
When it is determined at step 610 that a new network management object 412 was not included in the received network stack component, e.g., component 406, the new stack component 406 is associated with a generic network management object 410 in association with the network service manager 414 of the controller 108 at step 612. Operations then proceed to step 616, whereupon common network communication features are mapped via a suitable network interface stack. When the controller 108 determines at step 610, that the received network stack component includes a corresponding network management object, e.g., component 408 and associated object 412, flow proceeds to step 614, whereupon the new network management object 412 is added to the network management objects 410 and 412 available to the network service manager 414 operative on the controller 108. Thereafter, at step 616, common network communication features are mapped via the network interface stack. The skilled artisan will appreciate that common network communication features are thus mapped using the network management object 410 or 412 associated with the new network stack component 406 or 408, by the network service manager 414.
At step 618, a network stack associated with an installed network communication component is then sensed by the network service manager 414 of the controller 108. Flow then proceeds to step 620, whereupon any sensed communication components associated with a predefined network stack component are registered with the network service manager 414. The network service manager component 414 associated with the controller 108 then maps, at step 622, features associated with sensed components to common network communication features. The network service manager 414 associated with the controller 108 then commences network services at step 624 in accordance with the mapped features associated with the sensed network communication component. At step 626, configuration file data 418 corresponding to the commenced network services is then communicated to an associated data storage 110. In accordance with one embodiment of the subject application, the configuration file data 418 is an
XML configuration document. A suitable example of a corresponding XML document is shown below:
Following the communication of the configuration file data 418 at step 626, flow proceeds to step 628, whereupon the operations of the commenced network services are tested by the network service manager 414. A determination is then made at step 630 whether the newly installed network service has been successfully started. When the service was unsuccessfully started, configuration file data 418 corresponding to a last known good configuration is retrieved from the associated data storage device 110 at step 632. Flow then proceeds to step 634, whereupon network services are then selectively restarted according to the retrieved configuration file data 418 by the network service manager 414 and flow returns to step 630. Upon a determination at step 632 that a service has been successfully initiated, normal operations of the document processing device 104 are commenced at step 636. A determination is then made at step 638 whether alteration data has been received from an administrator. That is, the document processing device 104 performs normal operations until an administrator, via a thin client interface, communicates alteration data to the document processing device 104. When no alteration data has been received, flow returns to step 636, whereupon normal operations of the document processing device 104 continue. Upon the receipt of alteration data, flow proceeds to step 640, whereupon the configuration file data 418 is modified to incorporate the changes received from the administrator. Network services are then selectively restarted at step 634 in accordance with the changes to the configuration file data 418 and upon successful restart, as determined at step 630, normal operations of the document processing device 104 are commenced shown at step 636.
