Hi Masataka-san, 1. Thank you for sharing your interesting experience with the JPIX trial service based on 464XLAT. Could you, for clarification, describe in more details formats of XLAT prefixes in this trial?
2. Objectives of 464XLAT and 4rd-U look very similar (ref draft-despres-softwire-4rd-u-01). Indeed: - Both use "DHCPv6 prefix delegation or another method" to inform CLAT/CEs of their IPv6 prefixes. - Both "can implement traffic engineering based on IPv4 source address and IPv4 destination address" (a feature that, as noted in your draft, is missing in encapsulation). OTOH, unless I miss something, 464XLAT doesn't provide incoming connectivity of CLATs in case of shared IPv4 addresses (while 4rd-U does provide it to CEs). In this respect 4rd-U seems functionally more complete. Thoughts?
