I have done the review of the draft below as per RFC 6390

The RFC mostly conforms to the RFC 6390 recommended format (separately
noted in a section "8.  Compliance with RFC6390 guidelines"). There
are some small changes that might make the document more clear and
readable.

1. Define steady state explicitly - there is an attempt made though
noting that when the alternate color is being marked in the flow but
calling it out would make it clearer.

2. It might be useful to also explicitly state what the timeout should
be for marking the packet as marked. Currently it seems that it is
left as an exercise to the implementer of the draft. One way could be
to not consider the packets when the same colour is marked again on
the flow. The old packets of the same colour "expire" or are lost. For
example the draft recomends 5 min fr switching the colour. A similar
recommendation might be made for marking packets as lost after a
certain timeout (either as a percentage of the measurement period or a
flat time).

3. There are two sections - Normative and Informative. The draft
addresses the normative and informative parts except the verification
section of the informative part. If it is not applicable (may not be
possible to reproduce results for verification), then it should be
explicitly noted in the draft.

Regards
Vinayak
