Hi all,

I had reviewed the draft already, but I have no knowledge to comment on the
metric model. As far as security issue is concerned, since this is a active
measurement, it suffers the drawbacks of injection of measurement traffic which
is listed well in section 9.

They should see if their model complies with RFC 1262: guideline for Internet
measurement activities. It can also help if they can mention what is the
threshold percentage of measurement traffic that is tolerable and if they can
quote an approximate percentage of measurement traffic needed to inject
according to their loss metric and if it is acceptable.
