Hi Marco,
in general I agree: the discussion on fast handover solutions has
somewhat gotten out of hand.
Regarding RFCs 6058 vers. 5568/5949: I didn't mean to say they do the
same - still use cases appear very similar. More precisely from the
documents:
* 5568/5949: "improve handover latency"
* 6058: "ensures optimized forwarding of [...] packets"
Maybe you can clarify the differences?
Otherwise, the subject of the debate is the adoption call of
draft-schmidt-multimob-fmipv6-pfmipv6-multicast. In a previous, detailed
offline discussion you were supporting the adoption of both drafts
(draft-contreras-multimob-rams and
draft-schmidt-multimob-fmipv6-pfmipv6-multicast).
Maybe you can clarify, as well?
Cheers,
Thomas

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, in particular not in the context of the
current Multimob discussion whether or not to go for one
selected or 4 protocol specifications.

http://tools.ietf.org/html/draft-hui-multimob-fast-handover-04
This draft is - if you want so - a competitor to
draft-schmidt-multimob-fmipv6-pfmipv6-multicast, but has never been
worked out (as have several other attempts in the past). If this
document was to be advanced, it had to rewrite (or copy ??) 80 % of
our draft, which is not a proper way to treat authorship.
===>
I aggree draft-hui-multimob-fast-handover-04 is a competitor of
draft-schmidt-multimob-fmipv6-pfmipv6-multicast. Further more,
draft-hui-multimob-fast-handover was written in June 2009 and after
this draft was submitted for more than half a year, other similar
draft was submitted and have a lot common idea of our draft. So I
really do not see why someone say if this document was to be advanced,
it will need to "COPY" 80% of
draft-schmidt-multimob-fmipv6-pfmipv6-multicast?
To Behcet:
1. First of all, may I ask why IETF need more than one solution for
one problem?
2. If the group have decided to allow more than one WG draft forthis
problem, I then also request the group to consider
draft-hui-multimob-fast-handover-04 as one basis of WG document.
Two answers:
1. There may be several solutions for different scenarios on the same
problem scope, as the unicast-people worked out several solutions (i.e.,
MIPSHOP worked out the (P)FMIPv6 handover solution and the transient
binding in parallel.
2. draft-hui-multimob-fast-handover-04 has never been worked out. In fact,
it merely repeats incomplete work that has been around for years, the first
draft with incomplete sketches on fast handover has been
http://tools.ietf.org/html/draft-suh-mipshop-fmcast-mip6-00 in 2004!
So the argument we were presenting is: there is reason and need for this fast
handover solution, and we should adopt the document that is most mature,
completely worked out and discussed many times in the WG.
Cheers,
Thomas
