[alto] Proto writeup for ALTO deployment draft

["Vijay K. Gurbani" <[e-mail]>]

All: I am the shepherd for the ALTO deployment draft.  The draft
is close to being done and the working group is awaiting the release
of version -14.

In preparation of moving the draft ahead when version -14 becomes
available, I have filled in the proto-writeup as indicated below.
Let me know of any issues and concerns with the writeup.

Thanks.

1. Summary.

Vijay K. Gurbani is the document shepherd for draft-alto-deployments draft.
Spencer Dawkins was the responsible AD throughout the last few versions 
of the
draft, however, that benefit transferred to Mirja Kuhlewind around IETF 95
(Buenos Aires).

The document itself has a long and varied history, having started life 
off as
a -00 document targeted to the ALTO WG as an individual (original authors:
Martin Stiemerling and Sebsatian Kiesel, March 1, 2010).  It 
transitioned to a
WG document in February 2011 with the original two authors and continued on
revision trajectory until version -04 when new authors were added.

The document distills and prescribes recommendations for network
administrators and application designers planning to deploy ALTO, including
recommendations on how to generate the ALTO map information and known
limitations of the ALTO protocol (rfc7285).  Furthermore, the document
provides guidance for the use of ALTO in diverse environments, including P2P
traffic optimization, CDN considerations, application guidance in VPNs, to
name a few examples.

The working group is targeting this document as an Informational, which 
is the
appropriate track the document should be on based on the nature of its
prescriptions and recommendations.  The document does not introduce any new
protocol elements, nor does it subvert --- positively or negatively --- the
usage of the protocol in any given particular environment (i.e., CDNs, VPNs,
or P2P environments).

2. Review and Consensus.

The draft has consensus from the WG and has been well-reviewed.  There have
been two WGLCs for this draft: Version -11 of the draft was last-called
between the time period of April 28, 2015 to May 17, 2015.  During this
period, the draft was reviewed in detail by Wendy Roome.  Wendy found 
several
minor issues and nits and a couple of major issues, all of which were
readily addressed in version -12 (June 2015).

Pursuant to an ALTO virtual meeting held on October 27, 2015, it became
apparent that draft-siedel-alto-map-calculation could inform
draft-ietf-alto-deployments.  The authors of the two drafts were 
requested to
make a determination whether portions of the former could be included in the
latter.  By November 2015, a determination was made that relevant portions
from the map-calculation draft could be put into the 
deployment-considerations
draft.  The issue at hand after this was done was whether the changes
percolated widely enough to have a second WGLC.  By Jan 2016, it was decided
that a second WGLC was likely, and thus a second one was issued that ended
on February 3, 2016.  The second WGLC was reviewed by Sabine Randriamasy,
resulting in version -14 that addressed her review.

In summary, the deployment draft has had excellent support from the working
group, has been reviewed on multiple occasions by various members of the
working group and has been last-called twice to account for the expanded 
role
it took on as the working group became aware of the growing deployment 
of the
ALTO protocol.

3. Intellectual Property.

The shepherd confirms that each author has stated to him (and ALTO 
co-chairs)
their direct, personal knowledge that the authors are not aware of any IPR
related to this document.

To the best of the shepherd's knoweldge, there has not been any 
discussions on
IPR related to this document on the ALTO WG mailing list.

4. Other Points.
<To be enumerated when -14 becomes available.>

Thanks,
