Re: [v6ops] scenario of draft-zhang-v6ops-ipv6oa-iwf-00.txt

hi

   I just describe the usecase of IPv6oA, but we discuss more in the draft including ND proxy,link layer address change... It's not just a requirement, i think

Hello,
   If I understand your draft correctly you are proposing a new interworking function on the Access Node, so you are basically specifying new requirements for the Access Node.
Why are you discussing this topic in IETF? Isn't this Broadband Forum's territory? BBF is the SDO that specifies requirements for Access Node and if I remember correctly this interworking function was discussed and finally not included in TR-177 some years.
If you think this work is needed, for the scenario you described, I would suggest discussing this proposal in BBF first.
Best Regards,
Roberta

Subject: [v6ops] senario of draft-zhang-v6ops-ipv6oa-iwf-00.txt
HI,
    The senario of IPv6oA is exist in Chinatelecom network. In our IPV4 network some of our customers uses a service called ATM private-Line. In this service, user's CPE device connect to core network by IPoA (PVC/SVC) , and uses stable IP address. In the future, with the development of IPv6 ,these customer will hope to transfer their service to IPv6,but they donot want to use IP access network(maybe they donot want to change their network sharply). In this secanrio, we think IPv6oA will be a choice to solve the problem. And upgrade a IPv4 IWF to DS IWF may be economical
