During my review of this document I noticed the following issues
that the authors and ISE may want to address.

---

There are some abbreviations that should be expanded on first use. 
Note that Section 2 covers many of these terms but comes later in
the document.

---

The term "mobile VM" is introduced without explanation. Indeed, the
idea that a VM might be seamlessly mobile within a data center has
been debated by the IETF and considered unlikely because of problem
of moving and synchronising associated state. The idea of
seamlessly moving a VM between data centers was considered
correspondingly complex. Thus, in using this term, the authors
would be well advised to give a very clear description of their
understanding of a "mobile VM", what features are associated with
such mobility, and under what circumstances such mobility might be
employed.

---

[ARMDStats] seems to be present twice in 6.2

---

This document is positioned as Experimental which is fine. but the 
document does not set out the scope of the experiment, how the 
experiment might be contained, and how the experiment may be
judged.

---

The term "hypervisor" is used freely without reference or
explanation. This may be a sufficiently new concept that some hints
would be useful.

It is not clear what the boxes marked "ACC" in figure 2 represent. 
Similarly "Agg" in figure 3.

The only issue I have is that an IESG statement on an Independent stream document comes with a great deal of subtext, if only due to how rare they are.  It's essentially saying that we think this is a bad idea and you shouldn't do it.  No, it doesn't say that, but that's the subtext.

I do not have a strong opinion on the recommended evaluation, but as I read draft-nachum-sarp, I was unable to understand how it works in detail on IPv6 and whether there's an effect to SeND (RFC 3971). The IPv6 details that I was unable to understand relate to whether there are impacts to SLLA and TLLA options in ND.

Finally, the currently recommended IESG note does not mention RFC 4541; at least for IPv6 it would seem to provide some level of optimisation to the problems discussed in the document and in ARMD.

In any case, scaling of very large networks is an issue. What I want to convey is that there are a multitude of solutions that address the situation in their specific ways.

I would be pushing back on Barry's DISCUSS if RFC 7342 were standards track.  However, I note that even in the case of ZRTP vs. DTLS-SRTP, there's no IESG note on the loser (RFC 6189).

To be clear, I would be a No-Obj on the RFC 5742 position being proposed. What follows is about the proposed IESG Note.

I realized after Pete's helpful list of the alternatives (which omitted No Position, and that was also a possibility I considered), that I hadn't thought carefully about balloting when we had IESG Notes on conflict reviews. 

I searched my IESG mail folder for the last two years, and found two conflict reviews that had IESG Notes (the curious can keep reading past the first "--" to see them).

It seems to me that neither previous conflict review was as robust as the one I'm looking at on this telechat. 

I'm not comfortable saying something in an RFC that the community could say at "BOF time"/"WG charter time"/"IETF Last Call time" if anyone did try to take this work forward. For me, I'm balloting on a proof by assertion that I can't evaluate on my own.

Having said that, the threshold of "yes plus no-obj" ballots required for approval on a conflict review is really low, the IESG is well within its rights to add the proposed IESG Note, and me Abstaining won't change a thing, nor should it, so ... I'm Abstaining.

And thanks, Barry, Pete, and Stephen, for helping me choose a more appropriate position for me.

The IESG has completed a review of draft-irtf-samrg-common-api-08
consistent with RFC5742.

The IESG recommends that 'A Common API for Transparent Hybrid Multicast'
<draft-irtf-samrg-common-api-08.txt> NOT be published as an Experimental
RFC.

The IESG has concluded that this document extends an IETF protocol in a
way that requires IETF review and should therefore not be published
without IETF review and IESG approval.

IESG NOTE:

Specifically, the document appears to propose incompatible extensions
to URIs: using URIs with unregistered schemes (ip: and sha-2:, for
example) and using registered schemes, such as sip: and reload:, in
ways they were not intended to be used and that deployed software
would not support.

This document seems to be overloading URIs to make them serve as
multicast group names, and overloading URI schemes to serve as
namespaces in the proposed SAM system.  Having identifiers that look
like URIs but have different semantics and are used in different ways,
is a very bad approach and is likely to cause serious breakage as
those identifiers become intermixed with and indistinguishable from
true URIs that applications expect to dereference.

The IESG would also like the IRTF to review the comments in the
datatracker related to this document and determine whether or not they
merit incorporation into the document. Comments may exist in both the
ballot and the history log.

The IESG has completed a review of draft-hausenblas-csv-fragment-07
consistent with RFC5742.

The IESG has no problem with the publication of 'URI Fragment Identifiers
for the text/csv Media Type' <draft-hausenblas-csv-fragment-07.txt> as an
Informational RFC.

The IESG has concluded that there is no conflict between this document
and IETF work.

The IESG asks that the following IESG note be attached to the document:
The change to the text/csv media type registration requires IESG
approval, as the IESG is the change controller for that registration.
The IESG has, after consultation with the IETF community, approved the
change, which is specified in Section 5 of this document.

The IESG would also like the RFC-Editor to review the comments in the
datatracker related to this document and determine whether or not they
merit incorporation into the document. Comments may exist in both the
ballot and the history log.
