ftp://ftp.pwg.org/pub/pwg/BOFs/cwmp/white-cwmpmfdmodel10-20120604.pdf

• Use cases, deployment scenarios, Requirements for a CWMP-based standard model for remote management of printers/MFDs

• Recommend a machine translation approach for developing the CWMP standard Data model for all imaging devices that must be consistent with the PWG standard data model in XML Schema.

• An XML document instance fragment of a CWMP PrintService Data Model.

• Pointed out some of the difficulties in transforming the existing PWG Semantic Model XML document schema into a BBF data model.

Status – White Paper


Status – CWMP Data Model

• The first Machine translation of PWG Print Service XML Schema to TR-106 based CWMP Print Service XML Schema is complete with issues for future enhancements. Thanks for Celstream engineering team’s impressive speed.

• A list of CWMP data elements are implemented in the CWMP proxy of a connected printer. (see next slide)

• The CWMP proxy uses IPP, SNMP, or HTTP protocol to gather data from the physical printer.

• The CWMP proxy may be implemented in a physical printer’s firmware that provides the printer’s CWMP management data directly to ACS over the internet.

• The demo will show that a local or remote CWMP management app can get and set the printer/print service properties in the CWMP data model of a printer from the DeviceMaestro in ACS that communicates with the CWMP proxy that communicates with the printer via SNMP, or HTTP with EWS.

Status - PWG-BBF Collaboration Project

• The project was formally approved by BBF CEO and the CWMP Working Group in Feb. 2013.

• Thanks for BBF CEO, CWMP WG Officers’ leadership and full support, and Marvell Technology’s assistance.

• The documents on PWG’s CWMP data model for imaging devices were sent to CWMP WG for an expert review and providing feedbacks.


CWMP Demo

CWMP mapping to SNMP MIBs, IPP and native TR069 stack


Demo Objectives

• Demonstrate a potential CWMP Data Model for MFDs that is compliant to PWG standards• Communication to/from an ACS server (implemented in the

DeviceMaestro server)• Communication through a proxy to printers

• via SNMP to talk printer MIBs • and/or embedded web servers via http

• Communication directly with an embedded TR069 client emulator.


Disclaimer

• This is a technology demonstration and only selected SNMP attributes mapped to CWMP Data Model are implemented.

• SNMP capable local and remote printers will be used and will be subject to the capabilities they support.

• This is not meant to demonstrate the Thinxtream DeviceMaestro solution, but restricted to CWMP and PWG standards mapping.

Next Steps

• Collaborate with BBF CWMP WG experts• Review and validate the XML schema of the

translated CWMP data model for printer/print service

• Enhance and resolve any issue with the current CWMP data model for imaging devices.
