Re: [Ieprep] Re: WG Review: Recharter of Internet Emergency Preparedness (ieprep)

[Janet P Gunn <[e-mail]>]

It seems to me that there are two separate issues.

First, should this work be done within IETF, or would it be better done in
ITU (or ATIS, etc.)?

Second, if it is done within IETF, should it be done in IEPREP, or some
other working group?

In Sam's earlier emails, he seemed to be saying that this work belonged in
ITU.  However his latest email accepts that a large amount of the work DOES
belong in IETF.

So that leaves the question of where (within IETF)  the work should be
done.  Since most of the "pieces" are related to existing IETF protocols,
in principle, the various extensions could each be addressed in the
relevant (non IEPREP) working group.

There are two problems with this.  The FIRST is that there is a need to
coordinate and "system engineer" the different "pieces" so that they will
work together, both at the requirements level and at the deployment level .
That fits well within the original charter of IEPREP, in terms of both
Requirements documents, and BCP documents.

In the particular case of SIP RPH, IEPREP served us well  in generating the
requirements document, which were passed on to SIPPING and SIP.  Now that
RPH has become RFC4412, and as we attempt to deploy it in the field, it is
clear that there will be a need for at least one BCP addressing the best
way to USE RFC4412 to meet each set of objectives.  (It is already clear
that there will be some distinct differences in the deployment of RFC4412
in the DoD "preemption-based" namespaces, and in the "public carrier"
"non-preemption-based" namespaces.)

There will also be new requirements.  Long term plans include the expansion
from voice to other  SIP-related services such as video conferencing, as
well as to non-SIP services such as email, file transfer, and even web
access.  IEPREP is the right place to work through these requirements.
The IEPREP working group needs to continue (even if restricted to the
original charter) to address these points.

The SECOND problem is logistics.  Every working group in IETF has limited
human resources to do the actual work.  The ones where the IEPREP "pieces"
COULD be pursued seem to be particularly  overworked.  As a result, the
IEPREP-related IDs tend to be viewed as the "poor stepchild" and have
difficulty getting working group status.  Even when they do get working
group status, they tend to progress rather slowly, because the working
group as a whole does not consider them high priority.  IEPREP, however,
provides a context in which these "pieces" DO have the critical mass to
progress at a more reasonable rate.   Coordination with  all other relevant
working groups is, of course, essential.

There are also IEPREP related IDs (both requirements related and solution
related) that have been unable to find a "home" in any other working
groups.  The ID addressing email priority in MTA to MTA transfer is such an
example.

It is for this reason (new work that  cannot find a home in any of the
current working groups, as well as work that is the "poor stepchild" in
current working groups) that the IEPREP charter needs to be extended to
include "mechanisms" as well as just requirements and BCPs.

I whole-heartedly agree.  I believe the DoD must extend its notions of
Precedence and Preemption to all applications, voice, video, web, ftp,
mail, etc.  Mechanisms/protocols must be defined and consistent across
applications and their interactions with services, e.g., DNS, SIP, etc.,
and with their interactions with transport protocols, e.g., TCP, and IP.
  Mechanisms must apply for session and non-session based applications
and therefore cannot solely be handled through extensions to SIP
signaling.  Mechanisms/protocols must provide the necessary security,
authentication and access controls for all of the applications types as
well.

I strongly believe that the IETF is the place to address these issues.
And I think they are best served in a coordinated fashion within the
guidance of a single working group with liaisons to other working groups
and organizations.

Thanks,
Bob
