The value of the protocol number in the IP packet header.
The protocol number identifies the IP packet payload type.
Protocol numbers are defined in the IANA Protocol Numbers
registry.

<paragraph>
In Internet Protocol version 4 (IPv4), this is carried in the
Protocol field. In Internet Protocol version 6 (IPv6), this
is carried in the Next Header field in the last extension
header of the packet.

TCP control bits observed for the packets of this Flow.
This information is encoded as a bit field; for each TCP control
bit, there is a bit in this set. The bit is set to 1 if any
observed packet of this Flow has the corresponding TCP control bit
set to 1. The bit is cleared to 0 otherwise.
</paragraph>
<paragraph>
The values of each bit are shown below, per the definition of the
bits in the TCP header <xref type="rfc" data="rfc793"/><xref type="rfc" data="rfc3168"/><xref type="rfc" data="rfc3540"/>:

<paragraph>
As the most significant 4 bits of octets 12 and 13 (counting from
zero) of the TCP header <xref type="rfc" data="rfc793"/> are used to encode the TCP data
offset (header length), the corresponding bits in this Information
Element MUST be exported as zero and MUST be ignored by the
collector. Use the tcpHeaderLength Information Element to encode
this value.
</paragraph>
<paragraph>
Each of the 3 bits (0x800, 0x400, and 0x200), which are reserved
for future use in <xref type="rfc" data="rfc793"/>, SHOULD be exported as observed in the
TCP headers of the packets of this Flow.
</paragraph>
<paragraph>
If exported as a single octet with reduced-size encoding, this
Information Element covers the low-order octet of this field (i.e,
bits 0x80 to 0x01), omitting the ECN Nonce Sum and the three
Future Use bits. A collector receiving this Information Element
with reduced-size encoding must not assume anything about the
content of these four bits.
</paragraph>
<paragraph>
Exporting Processes exporting this Information Element on behalf
of a Metering Process that is not capable of observing any of the
ECN Nonce Sum or Future Use bits SHOULD use reduced-size encoding,
and only export the least significant 8 bits of this Information
Element.
</paragraph>
<paragraph>
Note that previous revisions of this Information Element's
definition specified that the CWR and ECE bits must be exported as
zero, even if observed. Collectors should therefore not assume
that a value of zero for these bits in this Information Element
indicates the bits were never set in the observed traffic,
especially if these bits are zero in every Flow Record sent by a
given exporter.
