Type: Technical
Reported by: Bart Overkamp <bart@bedrijfzondernaam.nl>

Section: 4.2.1

Original Text
-------------
                                                            <...> We
   RECOMMEND both the client and the server to retransmit SYN and SYN-
   ACK packets without the cookie options on timeouts.  This ensures the
   connections of cookie requests will go through and lowers the latency
   penalty (of dropped SYN/SYN-ACK packets).

Corrected Text
--------------
                                                            <...> We
   RECOMMEND both the client and the server to retransmit SYN and SYN-
   ACK packets without the cookie options on timeouts.  This ensures the
   connection requests will go through.

Notes
-----
With a retransmitted SYN or SYN-ACK packet without cookie options it does not follow that 'cookie requests' will go through, however 'normal' TCP connection flow does continue. This comes with a latency penalty.
