Re: [pcp] FW: New Version Notification for draft-rpcw-pcp-pmipv6-serv-discovery-01.txt

Hello authors,

Few questions are below trying to make further clarifications.

1. I have a little confusion on the statement
"   If the dynamic outbound mapping is for the local access network then
   there are two cases to consider - In the first case where there is a
   nested NAT[I-D.penno-pcp-nested-nat], the mobile access gateway will
   function as both PCP server and PCP proxy forwarding the accepted PCP
   request to CGN PCP server.  In the second case, where there is no
   CGN, mobile access gateway will function as a PCP server in the local
   access network.
"
When the traffic is heading to the NAT in local access network, there
is no NAT processing in homenet. Wondering to know what is the case of
nested NAT you refer to?

2. What is the goal of designing mobility options? I read the Section
3, it seems a smart PCP proxy is sufficient to handle the traffic
dispatch? what the consideration to this option?

3. How do you handle the case of IPv6 offloading?

Best Regards

Gang
