The dual-stack lite mechanism provide an IPv4 access method over IPv6
ISP network for end users. Dual-Stack Lite enables a broadband
service provider to share IPv4 addresses among customers by combining
IPv4-in-IPv6 tunnel and Carrier Grade NAT. However, in dual-stack
lite. CGN has to maintain per-session address mapping, which could
be a heavy burden, and produce high hardware cost as well as
performance issue. This draft propose the lightweight 4over6
mechanism which moves the translation function from tunnel
concentrator (AFTR) to initiators (B4s), and hence reduce the mapping
scale on CGN to per-customer level. For translation usage, the
mechanism will allocate port restrcted IPv4 addresses to initiators
in a flexible way independent of IPv6 network in the middle.
