RE: Last Call: <draft-trammell-ipfix-tcpcontrolbits-revision-04.txt> (Revision of the tcpControlBits IPFIX Information Element) to Informational RFC

2013-10-08 04:48:24
Hi all,

A small editorial nit: RFC 793, RFC3168 and RFC3540 (which is experimental, 
BTW) all classify bits 3,4,5 in octets 13 and 14 of the TCP header as 
"Reserved".

In the information element according to this draft, the corresponding bits are 
named "Future Use", with the reference "per the definition of the bits in the 
TCP header [RFC0793]". Strictly speaking, this terminology differs slightly to 
RFC 793 and the very well-known figure depicting the TCP header.
 
For whatever it is worth, I suggest to better explain the different wording. 
For instance, instead of ...

      Each of the three future use bits (0x800, 0x400, and 0x200) should
      be exported as observed in the TCP headers of the packets of this
      Flow, as they may be used subsequent to a future update of
      [RFC0793].

... an alternative wording better reflecting the exact header definition in RFC 
793 could be:

      Each of the three future use bits (0x800, 0x400, and 0x200) should
      be exported as observed in the TCP headers of the packets of this
      Flow, which are reserved for future use in [RFC0793].

Best regards

Michael

Abstract


   This document revises the tcpControlBits IPFIX Information Element
as
   originally defined in [RFC5102] to reflect changes to the TCP Flags
   header field since [RFC0793].
