Subject: [v6ops] discussion of transition technologies


The WG Chairs were discussing the various transition technologies at some
length today.
I mentioned a previous conversation in another forum that led to this list
of networks and their mechanisms:

(Corrections and additions encouraged, especially with links)

Our impression was that of the 26+ transition mechanisms defined, only a few
have any modern relevance (editorial comments are mine, not consensus
positions):
6rd.   It may be that its light is waning, with early deployments moving to
native IPv6, and no new deployments.
DS-Lite.   Widely deployed, existing support among home gateway
manufacturers.
NAT64/464xlat.   Implies NAT64, SIIT, which may be used elsewhere. Handset
CLATs. No home gateway CLAT yet.
MAP-T.   Announced trials and lots of buzz, but no large-scale deployments,
no home gateway support yet.
MAP-E.   Some buzz, no announced trials or deployments, no home gateway
support yet.
Native dual-stack.   Still the gold standard, but doesn’t solve IPv4 address
shortage.

(Note that “yet” may change at any time).
As a matter of discussion, do you agree?
To guide our work, is there work we should do to document or deprecate any
of these?

Thanks,

Lee
