Dear all,
Dave rightly expresses in the Softwire meeting the need to separate/clarify
discussion about:
- Stateless vs stateful
– Static vs dynamic port sets
The need to clarify is IMHO even larger than that.
I therefore worked out a way to present the range of solutions to be compared,
with the following taken in consideration:
- The stateless/stateful IPv4 across IPv6 comparison isn't limited to IPv4
shared addresses (applies also to exclusive IPv4 customer addresses).
- If there is, in BR/AFBR's, no Customer state (i.e. no states referring to
individual IPv6 prefixes), there can't be per-transport-connection state either.
- CE-CE direct paths are possible only if IPv4/IPv6 mappings of BR/AFBR's don't
depend on Customer state.
The proposed document structure is as follows, with pros and cons for each
section:
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
Thoughts?
Regards,
RD
