Hi, Ali:
Here is my quick review to draft-ietf-avtcore-6222bis-01:
1. Section 1 and Section 3:
It is not clear how the section 1 is related to section 3?
Is this draft focusing on tacking linkability issue or deficiency issues described in section 3? 
What the linkability issue is? It is not obvious to a reader who are not familiar with this although this draft point to 
[I-D.rescorla-avtcore-random-cname] in the section 1?

2. PRNG needs to be expanded or point to a reference.

3. Section 6.1
The last sentence said:
"
A length of 96 bits allows on the order of
2^{40} RTCP CNAMEs globally before there is a large chance of
collision (there is about a 50% chance of one collision after 2^{48}
RTCP CNAMEs).
"
I am difficult to understand the rationale for this calculation since I don't know What "2^{40}" stand for?
How "40" is related to the length of 96 bits?

4.6.2
I can understand the first sentence, but I don't understand the second one. 
What kind of correlation need to be prevented? Why such correlation should be prevented?
Isn't this section focusing on talking about how to correlate sessions? What am I missing?

Regards!
-Qin

WG,

This WG last call has concluded. I think the level of reviews on this
document are very low. In the working group last call only Kevin Gross
and I have stated that they have reviewed the latest version.

Authors please address raised issues.

I will not consider this a successful WG last call unless at least one
additional person reviews it who are not an author. It is a very short
document and it also don't require massive amounts of additional
knowledge beyond basic RTP understanding to review.

Regards

Magnus Westerlund
WG chair
