Dear Naoki, However, in my honest opinion, I am confused a little about target technology in softwire. Well, me too. This is why I am trying very hard lately to understand things first. SA46T and SA46T-AS is just a tunneling technology. The other side, in my understanding, DS-Lite and

Dear authors, as far as I can understand your draft, you make NAPT44 in the CE obligatory. However, this is not the case for 4rd, dIVI, SA46T-AS and Lightweight 4over6 A+P drafts. So I suggest that you make it optional in 4via6 translation as well, since it might be desired for some

a real life meeting to hash out the stateless solutions is a splendid idea. But an expensive one too! Since the announced deadline for practical organization has already been passed, I personally believe that a better approach is to get enough Softwire time in Taipei for enough WG work. +1

Re: [Softwires] are multiple Domain IPv6 prefixes possible?

It seems to me, when delegating CE ipv6 prefix, a longest match might be used. But when forwarding a IPv4 packet, a longest match is useless, because domain 4rd prefixes don't overlap. Thanks, washam 2011/8/17 Rémi Després despres.r...@laposte.net: Le 17 août 2011 à 03:10, Jacni Qin a écrit :
