["George, Wes" <[e-mail]>]

The answers to our questions on two drafts are below. Please review and comment on the content of the answers, either together or separately. I'd like some discussion on the draft or the questions on-list before we get into the meeting.

Thanks

Subject: Asking for two 10min slots

Hi George,

Thanks for your kindly reminding. Sorry for my carelessness. :D May I ask for 2 time slots for draft-Li-Behave-NAT444-Test-00 and draft-tsou-stateless-nat44？Each presentation would last for 10min and the presenter will be Will Liu.

Following are my answers to your three question for both drafts:
Q:
1) describe the problem to be solved and show that there is widespread demand for a solution
2) demonstrate that the problem can not be solved with existing technologies
3) provide a description of the proposed solution along with its impact on current IPv4-only use and justification that it does not harm or delay the deployment of IPv6

A:
draft-Li-Behave-NAT444-Test-00
1) NAT444 is a common scenario in operators’ network.  Operators are worried whether applications will be affected when they pass though multi-level NAT. This test document provides experiences for both operators and researchers.
2) During testing, we find some problems such as QQ online Gaming doesn’t permit two user with the same public IP address in same game room.
3) This is a testing draft. Proposed solution is not related.

draft-tsou-stateless-nat44-00
1)  To let the NAT44 CGN simple, to reduce the cost of CGN. Different from traditional NAT44: no per-session state on the CGN, no binding table, no per-flow state to be maintained, zero log, high speed, easy to deploy hot backup.
2)  Traditional NAT44 CGN need per-session state on the CGN, binding table, per-flow state to be maintained. These make the CGN expensive and difficult to achieve CGN hot backup.
3)  Solve the exhaustion of IPv4 address when the network migrate to IPv6. Because it is stateless, the ISPs don’t need too much cost to deploy it. It can also be implemented in dual-stack network(IPv4 traffic pass through stateless NAT44 and IPv6 traffic pass by stateless NAT44), so the network can migrate to IPv6 smoothly.

Regards,
Will
