IPP> TES: Mandatory IPP notification agreement

Hi Peter and Henrik,

As a reminder to all - this is an IETF chartered working
group - such working groups do NOT make decisions in
face-to-face meetings (even at IETF Plenary sessions).
Decisions are made (and ratified) ONLY on the public
email discussion list.

The IPP mandatory notification method MUST be able to
politically survive the IESG review process.  

While I think the INDP is a good effort technically, I
strongly doubt that the IESG will like it as the mandatory
IPP notification method.  Unlike Email (SMTP) or MIBs (SNMP)
it interworks with no existing infrastructure, which is bad.

This mandatory notification method issue has also been 
discussed at some IPP WG weekly telecons (some I've attended).
But this is also NOT the forum for final decisions.

Lastly, Peter you jumped from port filtering by firewalls
to MIME type filtering - but the latter requires that the
firewall have an Application Layer Gateway (ALG) to figure
out the protocol and THEN to find the MIME type inside the
protocol envelope.

Personally, I agree with Henrik about selecting email as
the IPP mandatory notification method.

Cheers,
- Ira McDonald, consulting architect at Xerox and Sharp

Henrik,

>From the May PWG/IPP meeting minutes:
"4.6 Mandatory Notification Method?

After further discussion about a possible mandatory notification 

method, the group agreed that the INDP Notification method should 

become mandatory."

As for going through firewalls, the Bake-Off (hopefully) will test that
specifically.  Firewalls can be configured to allow specific traffic to
pass.  Some filter only on a port number and others examine content.   I
intend to have two firewall vendors at the Bake-Off with products that are
able to filter at least on the port number.  I hope at least one will also
be able to examine the MIME type.

Well it was my understanding that we didn't agree on a mandatory method.
And the INDP method
won't go through a firewall, so if you are searching for a mandatory method
I would say MAILTO.

All,

I am working the content planning for the IPP Bake-Off.  I want to be sure
that there is PWG wide agreement on the notification issue.

It is my understanding that INDP is the mandated IPP notification method.
There were some minor updates that have been agreed to and we are awaiting
the final version of the document for PWG last call.  The minor changes are
documented in the meeting minutes from May meeting of the PWG.    This
upcoming INDP document will be the document that the notification section
of
the Bake-Off will use as a base.

Is this correct or did I misunderstand?

Pete
