scope:

This Recommendation describes the scenarios and signalling requirements of unified intelligent programmable interface for IPv6 service deployment. The example signalling protocol procedures at this interface will also be described in this Recommendation to support protocol unaware flow forwarding in the data plane. The IPv6 technologies supported in this Recommendation will include, but not be limited to, the following: dual-stack lite (DS-Lite), IPv6 only, IPv6 rapid deployment (6rd), IPv4 residual deployment (4rd), mapping of address and port - encapsulation mode (MAP-E), mapping of address and port - translation mode (MAP-T), lightweight 4over6 (lw4over6) and 464XLAT.
