• First machine-translation by Celstream (February 2012)

• First CWMP Printer demo by Celstream (April 2012)

• Last CWMP BOF meeting at PWG F2F (October 2012)

• First approach to BBF (November 2012)

• First telecon w/ BBF (February 2013).


• White paper on CWMP data model for Printers and MFDs • Latest update in June 2012

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

• Defines use cases, deployment scenarios, and requirements for a CWMP standard data model for remote management of Printers/MFDs.

• Recommends a machine translation approach for developing a CWMP standard data model for Printers/MFDs that is based on the PWG Semantic Model XML Schema.

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

• Identifies various difficulties in transforming the existing PWG Semantic Model XML Schema into CWMP data model.

Status – White Paper


Status – CWMP Print Data Model

• The first Machine translation of the PWG Print Service XML Schema to TR-106 based CWMP Print Service XML Schema was completed in February 2012 with some issues for future enhancements. Thanks for Celstream engineering team’s impressive speed.

• A set of CWMP data elements are implemented in the CWMP proxy for a connected printer – see next slide.

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

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

• This 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 which in turn communicates with the Printer via IPP, SNMP, and HTTP EWS (embedded web server).

Status – PWG-BBF Collaboration

• This project was informally approved by BBF CEO and the PWG CWMP BOF team in February 2013.

• Thanks for BBF CEO’s response, PWG CWMP BOF members’ efforts, and Celstream’s and Marvell Technology’s assistance.

• The documents on PWG’s CWMP Printer Data Model were sent to BBF officers in May 2013 for expert review and model feedback.

CWMP Demo

CWMP mapping to SNMP MIBs, IPP and native TR069 stack


Demo Objectives

• Demonstrate a potential CWMP Printer Data Model that is aligned with IETF and PWG standards.• Communication to/from an ACS server (implemented in the

DeviceMaestro server)• Communication through a proxy to Printers

• via SNMP to IETF MIB-II, Host MIB, and Printer MIB

• via HTTP to embedded web servers

• via IPP to any IPP/1.1 compliant device• Communication directly with an embedded TR069 client

emulator.


Disclaimer

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

• IPP capable local and remote printers can be used, subject to the device capabilities they support.

• This is not meant to demonstrate the Thinxtream DeviceMaestro solution, but is 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.
