Section 6, pg.20 says:

<<  second paragraph of the section  >>

                                                             [...].  The
   Count field provides an opportunity for a denial-of-service (DOS)
   attack because it is 32 bits long.  If an attacking system set the
|  maximum value in Count (2**32), [...]

It should say:

                                                             [...].  The
   Count field provides an opportunity for a denial-of-service (DOS)
   attack because it is 32 bits long.  If an attacking system set the
|  maximum value in Count (2**32-1), [...]

Notes:

In the second paragraph of Section 6, near the bottom of page 20,
the maximum value given is too large. In the OWAMP specification,
I could not find any indication of a bias added to the Count value,
and thus the (hypothetical) range for Count is 0 .. 2**32-1 .

Thus, the RFC text needs to be corrected.
