We are looking forward to your detailed comments. with regards to document organization, would it be possible to: > - merge host 4over6 (draft-cui-softwire-host-4over6-06) with lightweight > 4over6 (draft-cui-softwire-b4-translated-ds-lite-03) > Qiong: I personally think it is a very good suggestion. Both "host 4over6" and "lightweight 4over6" share the common feature with stateful per-user-encapsulation, and "lightweight 4over6" is also an address sharing extension to "host 4over6". I think it would be reasonable to merge these two documents if the authors of "host 4over6" do not object to it. > - merge stateless 4over6 (draft-sun-softwire-stateless-4over6-00) with the > MAP effort > Qiong: ok. I will merge it with MAP effort.
