This document specifies a stateless 4over6 mechanism which moves the
translation function from tunnel concentrator (AFTR) to initiators
(B4s). It is used for service providers offering residual deployment
of the IPv4 service across IPv6-only domains. The concentrator will
record the full set of prefix mapping rules independent of the number
of subscribers, while the initiator will only keep a single rule of
its own sub-domain. The BNG devices can learn the rule set further,
to achieve traffic optimization between initiators. In this way, it
not only achieve scalability and simplicity feature benefits from
stateless address mapping, but also keep CPE functions simple.
Besides, flexible addressing and scattered IPv4 address blocks can be
supported as well. Traffic optimization can be deployed
incrementally when necessary.
