Abstract:
DS-Lite [RFC6333] describes an architecture for transporting IPv4
packets over an IPv6 network. This document specifies an extension
to DS-Lite called Lightweight 4over6 which moves the Network Address
Translation function from the DS-Lite AFTR to the B4, removing the
requirement for a Carrier Grade NAT function in the AFTR. This
reduces the amount of centralized state that must be held to a per-
subscriber level. In order to delegate the NAPT function and make
IPv4 Address sharing possible, port-restricted IPv4 addresses are
allocated to the B4s.
