Thanks for the correction.
The confusion came from my original proposal (copied below with asterisks
added), and carried forward in Gang Chen's answer, sorry for that.
<<
a) Stateful per transport connection (and also stateful per customer IPv6
prefix)
e.g. DS-lite with CGN
b) Stateful per customer IPv6 prefix (but Stateless per transport connection)
e.g. *** draft-cui-softwire-host-4over6-06
c) Stateless per customer IPv6 prefix (and also stateless per transport
connection)
- Hub-an-spoke
TBD
- Direct CE-CE paths (mesh)
. Encapsulation based
e.g. draft-murakami-softwire-4rd-00 alias
. Translation based
e.g. draft-murakami-softwire-4v6-translation-00
