Hi Carlos,

I was just flying over the rams/sial draft and saw my previous comments
untreated.
This was the transient binding below ... and IPv4 treatment ... and some
more details I had commented about 10 - 15 months ago, but cannot
quickly find my mail. Please have a look.
Regarding the transient binding, I thought Marco already commented on
that. I'm just pasting below what he said:
"Just a side note: As there was already some confusion during Vancouver
meeting and the reference to the transient binding extensions (RFC6058)
still shows up repeatedly, let me clarify one thing:
PFMIP6 and Transient Binding address different use cases, they
have been specified to address different problem spaces. It's
not appropriate to refer to these two unicast protocol extensions
in the multicast space [...]"
This was a different discussion. Marco said *PFMIP* and
*Transient*Binding* are different (which is obviously true) ... but your
draft is unrelated to *PFMIP* - it does transfer context via the LMA ...
just as *Transient*Binding* does. As mentioned earlier: It does not
appear smart to me if we define Multicast solutions that mirror unicast
approaches, but remain incompatible on the wire. (For a way how to do
unicast-integrated fast handover support see
http://tools.ietf.org/html/draft-schmidt-multimob-fmipv6-pfmipv6-multicast-07).
The second issue was *IPv4*support* - I suppose, PMIP acceleration
protocols MUST provide IPv4 support. I don't see this in the current
version.
Regarding further issues I raised longer ago, I searched, but cannot
find my old email ... if time permits, I should review the draft in more
detail.
Cheers,
Thomas
Probably Luis can add on top of that.
So I guess you wanted to say "*partially* addressing received comments"
Regarding the other comments you mentioned, please tell us which
specific issues you have on current version. When we said that current
version addresses all received comments, we truly believed that, though
it is possible we missed some by mistake (not intentionally). We are
actually looking forward for your review.
Thanks,
Carlos
Cheers,
Thomas

Hi,
as discussed today in the meeting, the following question was raised:
draft-ietf-multimob-fast-handover transfers context from pMAG via LMA to
nMAG - which in concept corresponds to the *Transient*Binding* in
unicast RFC 6058 http://tools.ietf.org/html/rfc6058.
draft-ietf-multimob-fast-handover does not even reference RFC 6058 ...
but probably should closely stick to the unicast solution.
So the question is about protocol systematics: Do we want unicast and
multicast protocol operations remain incompatible?
Cheers,
Thomas

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Multicast Mobility Working Group of the
IETF.
Title : PMIPv6 multicast handover optimization by the
Subscription Information Acquisition through the LMA (SIAL)
Author(s) : Luis M. Contreras
Carlos J. Bernardos
Ignacio Soto
Filename : draft-ietf-multimob-fast-handover-03.txt
Pages : 42
Date : 2012-10-22
Abstract:
This document specifies a multicast handover optimization mechanism
for Proxy Mobile IPv6 to accelerate the delivery of multicast traffic
to mobile nodes after handovers. The mechanism is based on speeding
up the acquisition of mobile nodes' multicast context by the mobile
access gateways. To do that, extensions to the current Proxy Mobile
IPv6 protocol are proposed. These extensions are not only applicable
to the base solution for multicast support in Proxy Mobile IPv6, but
they can also be applied to other solutions being developed to avoid
the tunnel convergence problem. Furthermore, they are also
independent of the role played by the mobile access gateway within
the multicast network (either acting as multicast listener discovery
proxy or multicast router).
