1. Introduction and Scope

IRTF research group RG guidelines and procedures are described in
[RFC2014] (BCP 8), BCP 8 [RFC2014],
and this document does not change those guidelines and procedures in
any way.

2. The IRTF is not Is Not the IETF

A number of proposals from experienced IETF participants for new IRTF
research groups
RGs have encountered problems because the IETF participants were
making proposals appropriate for the IETF, but not for the IRTF.
[RFC2014] describes the origin of IRTF research
groups, RGs but doesn't provide much
detail about the process, which is intended to be flexible and
accommodate new types of research groups. RGs. Lacking that detail, experienced IETF
participants fall back on what they know, assume that chartering an
IRTF research group RG will be similar to chartering an IETF working group, and group (WG),
follow the suggestions in [RFC6771] to gather a group of interested
parties, and then follow the suggestions in [RFC5434] to prepare for
a successful BOF and eventually, a chartered working group. WG.

Both of these documents are excellent references for proposals in the
IETF, but their suggestions may result in a proposal that is almost
the opposite of what the IRTF Chair is looking for in a proposal for
an IRTF research group. RG. The mismatches fall into some consistent categories, and
this document lists the ones that come up repeatedly.

The target audience of this document is IETF participants bringing
proposals to the IRTF.

It's worth noting that the IRTF Chair has substantial autonomy on
what research groups RGs are chartered and how they reach that stage.
This document reflects Lars Eggert as The IRTF Chair. Chair
at the time of writing is Lars Eggert.

2.1. Research and Engineering

"To me, the fundamental outcome of research is understanding, and
the fundamental outcome of engineering is a product" product." - Fred Baker. Baker

In some ways, research is about a journey, and engineering is about a
destination. If a researcher answers a question in a way that opens
another question, that can be success. If an engineer keeps working
on a product without finishing it, that is usually a failure.

Research can be open-ended, while engineering can come to a stopping
point when the result is "good enough" - -- good enough to ship.

"If it has to work when you're finished, it wasn't research, it
was engineering" engineering." - attributed to Dave Clark. Clark

2.2. Scope

IRTF research groups RGs have a scope large enough to interest researchers, attract
them to the IRTF, and keep them busy doing significant work. Their
charters are therefore usually much broader than IETF working group WG charters,
and research groups RGs often discuss different topics underneath the charter
umbrella at different times, based on current research interests in
the field.

IETF working groups WGs are chartered with a limited scope and specific
deliverables. If deliverables and milestones are known, the proposal
is likely too limited for the IRTF.

2.3. Timeframes Time Frames

IRTF research groups RGs bring researchers together to work on significant problems.
That takes time. The effort required by a
research group RG is likely to take at
least three to five years, significantly longer than IETF working groups WGs
envision when they are chartered.

2.4. Alternatives

IRTF research groups RGs are encouraged to explore more than one alternative approach
to the chartered problem area. There is no expectation that the research group RG
will "come to consensus" on one approach. The research group RG may publish
multiple competing proposals as research produces results.

IETF working groups WGs normally use the IETF consensus process (as described in [RFC7282]
[RFC7282]) to drive interoperable solutions into the market place.
That often includes reducing the number of approaches to something
manageable for an implementer, preferably one, whether that means
starting with an approach the working group WG participants agree on, or
considering alternatives with a view to picking one rather than
spending significant effort on alternatives that won't go forward.

The IRTF IRTF, as an organization organization, may also charter multiple research groups RGs with
somewhat overlapping areas of interest, which the IETF tries very
hard to avoid.

2.5. Process

All IRTF participants have the obligation to disclose IPR and
otherwise follow the IRTF's IPR policies, which closely mirror the
IETF's IPR policies, but policies; in all other aspects, IRTF research group RG operation is much
less constrained than IETF working group WG operation.

Each IRTF research group RG is permitted (and encouraged) to agree on a way of
working together that best supports the specific needs of the group.
This freedom allows IRTF research groups RGs to bypass fundamental IETF ways of
working, such as the need to reach at least rough consensus, which
IRTF research groups RGs need not do. The Therefore, the mode of operation of IRTF research groups RGs
can therefore also change over time, for example, perhaps becoming more like
IETF working group WG operation as the research the group has been progressing
matures.

2.6. Charters

The purpose of charters in the IRTF is to broadly sketch the field of
research that a group is interested in pursuing, pursuing and to serve as an
advertisement to other researchers who may be wondering if the group
is the right place to participate.

IETF working group WG charters tend to be very narrow, narrow. They are intended to
constrain the work that the working group will be doing, and they may
contain considerable text about what the working group will not be
working on.

2.7. Deliverables

There is no expectation that IRTF groups must RGs publish any RFCs, although many do.
Some IRTF research groups produce IRTF-stream RFCs, while others
produce Internet-Drafts that form the basis of IETF-stream RFCs, and
still others may deliver reports, white papers, academic journal
articles, or even carry out relevant high-level discussions that
aren't ever published, published but influence other research. IRTF groups RGs are
successful when they stimulate discussion, produce relevant outputs outputs,
and impact the research community.

IETF working group WG deliverables tend to be specific protocol,
deployment deployment, and
operational specifications, along with problem statements, use cases, requirements
requirements, and architectures that inform those specifications.
Almost all IETF working groups are chartered to deliver Internet
standards, which isn't an option for IRTF
research groups. RGs.

2.8. Completion

IRTF research groups RGs may produce the outputs they expected to produce when they
were chartered, but it also happens that researchers consider what
they've learned and start work on better solutions. This can happen
whether or not the research underway has been completed, and the
process can continue until the research group RG itself decides that it is time to conclude,
conclude or when the IRTF chair Chair determines that there is no more
energy in the group to do research.

IETF working groups WGs will typically conclude when they meet their chartered
milestones, allowing participants to focus on implementation and
deployment, although the working group WG mailing list may remain open for a time.

3. Now That You Know What Not To DO to Do

The current IRTF Chair, Lars Eggert, is fond of saying, "just "Just act
like an IRTF research group for a year, and we'll see if you are
one".
one."

There are many ways to "act like an IRTF research group". [RFC4440]
contains a number of points to consider when proposing a new research
group. RG.
Some possibilities include:

1. Identify and recruit a critical mass of researchers who can
review and build off each other's work.

2. Identify other venues that may overlap the proposed research
group, RG, and
understand what value the proposed research group RG provides beyond what's
already underway elsewhere.

3. Hold a workshop to survey work that might set the stage for a
research group RG
on questions of interest, perhaps in concert with existing
academic events.

4. If the proposed research group RG expects to have outputs that will ultimately
be standardized in the IETF, identify and recruit engineers who
can review and provide feedback on intermediate results.

But every proposed research group RG is different, so e-mailing the IRTF Chair to
start the conversation is a perfectly reasonable strategy.

4. Security Considerations

This document provides guidance about the IRTF chartering process to
IETF participants and has no direct Internet security implications.

5. IANA Considerations

This document makes no requests of IANA and the RFC Editor can safely
remove this section during publication.
