Hi all,

The announce draft is now available at tools.ietf.org/id/draft-despres-softwire-sam-00.
The section which describes the particular IPv6-via-NAT44 scenario is in section 3.1.1.

Note that the presentation in Anaheim is planned to be understandable without having looked at the draft before.
 
But comments are most welcome at any time.
Regards,

RD

> Draft-despres-softwire-sam-00, which I will post in a few days, contains an updated description of SAM, the generic Stateless Address Mapping mechanism which applies to a variety of scenarios.
> 
> Among those, one permits ISPs to deliver native IPv6 connectivity across legacy CPEs that only support NAT44 with port forwarding.
> This solution is like 6rd in that:
> - ISPs don't need to change their IPv4 infrastructures
> - They only need to operate gateways between these and their IPv6 accesses
> - These gateways are stateless
> It is unlike 6rd in that:
> - Legacy CPEs don't need to be upgraded
> - To exploit of their IPv6 addresses, hosts have to be upgraded to support SAM.
> 
> Operation considerations of this scenario are relevant to v6ops.
> A time slot for a presentation will be appreciated.
