I have reviewed this document as part of the security directorate's ongoing 

effort to review all IETF documents being processed by the IESG.  These 

comments were written primarily for the benefit of the security area 

directors.  Document editors and WG chairs should treat these comments just 

like any other last call comments.

A nit: in the first paragraph of section 2, the second sentence is outdated 

and should be deleted.

In paragraph 3 of section 4.2, given that there is no change to the 

TWAMP-test packet format, I assume we use the exact TWAMP-test packet format 

as defined RFC5357, so that the SID is not carried in the test packets. My 

question is that how the reflector just whether a TWAMP-test packet belongs 

to the same session/SID or not. Since per definition the testing message 

does not include SID, how to differentiate the testing message of different 

testing sessions after multiple testing started?

This is not obvious and the text should be improved to make it clear how 

this works.
