I see:
  5.4.  Timestamps

    The metering process MUST be able to generate timestamps for the
    first and the last observation of a packet of a flow at the
    observation point. The timestamp resolution MUST be at least the one
    of the sysUpTime [RFC1213], which is one centisecond.

I think I'd rather see a reference to RFC3418 instead of RFC1213.
We can do so by RFC-Editor note. May want to check with authors too.

On page 14 I see:


      9. type of service octet (in case of IPv4), traffic class
        octet (in case of IPv6)
   
Is that not better state as

      9. DSCP, which is set in the type of service octet (in case of IPv4),
        or in the traffic class octet (in case of IPv6)

---

  I would prefer to see the paragraph referencing RFC 2119 in section 2.

  Last paragraph in section 6.3.3 needs to be reworded.

  In section 10.2, an important point is left unsaid.  If the injection of
IPFIX traffic fool the network provided into thinking that a DOS attack is
underway, the countermeasures employed by the network provider may actually
deny service to real customers.

  The appendix needs to be moved up in the document.

---

Overall, I like it.  A couple of things jumped out at me, though.
This document goes to a lot of trouble to say exactly what is
exported (e.g. what fields, etc), except for two cases:

      8. byte counter
        Which bytes of a packet are counted MUST be defined exactly.

    20. multicast replication factor
        the number of outgoing packets originating from a single 
        incoming multicast packet. This is a dynamic property of   
        multicast flows, that may change over time. For unicast flows 
        it has the constant value 1. The computation of the factor MUST
        be clearly defined.

This document is defining what fields are being reported on;
why can't it also define these two things that must also be
defined?  Is it useful to have different ipfix protocols exporting
different measurements?


Also, at the end of 6.1 it kind of says "Plus other stuff related to inter-AS
routing if you want".  It's already in the MAY section; can't they just
list some concrete items related to inter-AS routing as 27, 28, ...?
I don't think it's useful to say what amounts to "plus anything else that
you might feel like adding that you think is relevant", since that doesn't
encourage different people to make the same choices.

---

This is a good document overall.

The applications include usage-based accounting.  They should cite RFC 2975,
and indicate that the particular niche for usage-based accounting would not
be met if reliability was not very high.  Section 5.1 reliability requirements
do not meet the needs, nor do the timestamping of first and last packet of
a flow, because the flow may have been mischaracterized and that is first and
last of different flows.  The way to satisfy this issue is to caveat the
discussion of usage-based accounting with strong words on reliability that
counter the comments on lesser reliability and more probabilistic techniques
for other applications of ipfix.

Requirements on the ipfix implementation - the document is long and I wonder if
the working group really meant the protocol's confidentiality and anonymization
features to be so optional -  SHOULD confidentiality, MAY anonymization.
Just for implementation.
