Do we need some mapping or interaction table of the function elements or tunnels (IP-in-IP or IP-in-non-IP) to show the relationship with DS-Lite unicast solution? Jacni>: As Yiu mentioned in another email, the co-location with unicast DS-Lite elements is more deployment specific, and I'm ok to remove the section 4.5. From the protocol perspective, I don't see there is necessary interaction with the unicast solution. [TT] Section 4.5 is good for the readers to understand the difference between unicast and multicast DS-Lite. I strongly suggest add some texts into this section like "the co-location of multicast elements with unicast DS-Lite elements is more deployment specific". #2 Section 6.2 Translation and encapsulation both uses the same mPrefix64 and uPrefix64, so mB4 could not determine whether to de-capsulate the packets only based on mPrefix64 and uPrefix64. Propose to change as "it checks whether the group address is in the range of mPrefix64, the source address is in the range of uPrefix64 and whether the next header of IPv6 header is 4." Jacni>:Currently, we only employ the encapsulation for date forwarding in the main text. [TT] I am not talking about translation solution in the main text. Even if in the encapsulation case, mB4 needs to determine whether to make de-capsulation or not.
