Hi,kiesel

Well done. 
Would you be kind to explain some issues?
1, Do you have some example in mind when you point out "Peer-ID" in Approach
#3? What kind of info can uniquely identify a client or provider behind
NATs? And what kind of info, which client can obtain without much effort,
can uniquely identify one without NATs other than IP Add.
2, As far as I know, there seems no way to figure out whether 2 clients are
behind the same NAT, therefore no good way to do intra-domain optimization,
even for Approach #3, #4 and #5. So could you tell how to do intra-domain
optimization in these scenarios?

Thank you very much.


Regards

Yingjie Gu
