Re: [MEXT] [Fwd: I-D Action:draft-ietf-mext-nemo-pd-02.txt]



Julien Laganier a écrit :
This draft went over WGLC and received some comments. The authors
 have produced this new version addressing the comments received.
We would like to ask people that provided commnets to check if they have been addressed before the april 1st. We will ship the document to the IESG by then.

I commented that figures are necessary: a simple topology and a simple message exchange. I could draw them.

Please do then.

Please see below three topologies and three message exchange diagrams.
They correspond to the first descriptions in nemo-pd-02 draft (the draft
does have more description than just that.)

What do you think about these 3 topologies and message exchange
diagrams?  Do you have any preferrence (the first is the simplest)?
