Section: 3.2.1

Original Text
-------------
This field is initialized at a random number and incremented
monotonically for each packet of the session flow of the
5-tuple.  The random-number initialization is intended to make
it harder to spoof and insert such packets.

Corrected Text
--------------
This field is initialized at a random number and incremented
sequentially for each packet of the session flow of the
5-tuple.  The random-number initialization is intended to make
it harder to spoof and insert such packets.

Notes
-----
The term monotonically increasing just means that the value must not decrease; it does not mean that it must increase. For example a monotonically increasing sequence may be: 1,2,2,2,2,2,2,2. On the other hand, a sequentially increasing example would be 1,2,3,4,5,6,7,8. I believe that the authors intended for the value to increase sequentially for each packet.
