Greetings:
I am submitting the following as a Charter draft for a Web Base Monitoring and Management Working group, in
line with the scheduled BOF at the January PWG Plenary. I invite comments. I have also established a
directory for materials related to this subject at ftp://ftp.pwg.org/pub/pwg/wsm (Web Services Management).
Harry, can we set up a mailing list so that we don't overload "announce" with project specific comments? Thanks.
Best regards,
Bill Wagner, NetSilicon

Charter Proposal for
PWG WEB-Based Device Monitoring and Management
Abstract
There exists a need for remote monitoring and maintenance of office imaging devices for several purposes, including:
1. Enterprise management and configuration of equipment in remote offices
2. Service Company monitoring of leased equipment or services for charging and maintenance
3. Equipment Supplier access of sold or leased equipment to maintain and update equipment
This need is has been intensified by the increased complexity of equipment in scattered locations and the
need to reduce costs of maintenance and support.
Various mechanisms have been used to provide remote maintenance, including
· telephone hookups, where the equipment calls out on a modem,
· built in radio paging transmitters,
· various network connections, often using a proprietary protocol
Telephone and pager solutions are costly both for the equipment and in recurring charges. Custom network
approaches typically require special MIS actions to communicate through the ever-necessary firewall.
There is no standardization among the various approaches, so that different implementations are not compatible.
The prevalence of the "Web" and the consistent support of Web Browsers across enterprise, soho and home
environments suggest an effective and inexpensive method of addressing this need. Indeed, there are
some implementations in place using this mechanism. Using the WEB to allow devices to contact an
internet-accessible management server parallels and may indeed compliment the structure resulting
from the PSI initiative.
As has been observed in the PSI charter, "When a new problem presents itself ... there will be some initial,
proprietary, solutions and some early adopters. Experience shows that standardizing certain critical
components of the solution and making the standard freely available assures interoperability among
implementations. This ultimately results in the broadest, most competitive market for the new
solution. Customer sentiment generally supports and reinforces this experience as long as the
standardization effort is concluded in a timely manner and the standardization process yields
widespread adoption and demonstrable interoperability."
In keeping with this, it is desirable to formalize the transport use in Web Based Device Monitoring and
Management and to standardize the method of communication in an extensible way to allow
interoperability between different manufacturers' imaging products and the various data base and
management programs involved in the remote monitoring and management.
In accord with this general objective, the working group should address:
Monitoring (both on an alert and a periodic basis)
Monitoring Configuration (identifying attributes to be monitored, frequency of monitoring,
conditions for reporting)
Management (configuring and/or controlling operation of the device)
Transfer of files to the Device (communicating executable updates, fonts, options, address lists etc,
along with the instructions of what to do with these files)
The implementation of these functions must address:
1. Costs
2. Security
3. Operability within typical enterprise network constraints
4. Compatibility with existing data base and management capabilities
5. Compatibility with existing and anticipated infrastructure, including MIBs, the Semantic Model and PSI.
6. Support of the installed equipment base as well as providing for inclusion in future equipment
To the extent possible, the working group should utilize protocols, techniques and procedures already in
place, both to leverage extant technology and to avoid conflict with or infringement upon proprietary
solutions. To this end, it should be aware of the work of the following organizations, as well as any
publicly documented proprietary solutions.
· IETF xmlconf activity (http://www.ietf.org/proceedings/02jul/index.html)
· IETF webdav (http://www.ietf.org/html.charters/webdav-charter.html)
· IETF BEEP (The Blocks Extensible Exchange Protocol Core {RFC 3080})(Mapping the BEEP Core onto TCP
{RFC 3081})
· OASIS (https://www.oasis-open.org/committees/mgmtprotocol/)
Milestones
Because of increased activity in this area and the increasing deployment of proprietary approaches, it is
important that the standardization activity proceed forthwith. On the other hand, the various aspects
must be given adequate consideration. The following schedule should be achievable, but may be to long. It
is suggested that the working group consider developing and disseminating a Monitoring Specification
first, and then proceeding to a full specification of the standard including more general Management capabilities.
