Dear Naoki, > Number of ports can be selected by prefix length.
I see. So essentially, SA46T-AS is like 4rd, but with a different port-allocation scheme. Also the "IPv4 plane" feature (you also call it "IPv4 VPN service") can be seen as a variant of multiple 4rd domains in 4rd context. Do you agree? If this is so, I don't really see why would we need a separate specification for this? I mean, we could also define various port-allocation schemes in the 4rd draft (as in RFC 6056, where we have various port randomization algorithms available for implementation).
