Dear authors,
While reviewing draft-ietf-ipfix-mediation-protocol, Rahul got some
feedback that actually concerns draft-ietf-ipfix-flow-selection-tech.
Can you please take this into account.
Regards, Benoit
Few comments.
1. Page 8:
1. The difference between "Intermediate Selection Process" and
"Intermediate Flow Selection Process" is not clear. Is the
first one selecting record purely on matching content (value
of the fields) in the record and the second one selecting on
matching attributes of the fields that are not part of the
record in *addition* to matching content in the record? An
example would help here.
BC> Granted, this is difficult to understand from the definitions only.
There is some history behind these two separate definitions. Anyway, you
get it right from your message above.
I was thinking to add to a section 2.1 "Differences between Intermediate
Selection Process and Intermediate Flow Selection Process" in the
draft-ietf-ipfix-mediation-protocol draft. However, thinking about it
some more, this section should really be done in
draft-ietf-ipfix-flow-selection-tech-14, to avoid some more confusion.
There is already section 3. "Difference between Intermediate Flow
Selection Process and Packet Selection". Some more text should be added
on the difference between Intermediate Selection Process and
Intermediate Flow Selection Process
When created, draft-ietf-ipfix-mediation-protocol will refer to that new
section.

1. Also in the example " e.g., Filteringonly records from a given
network to a given Collector" - Does "given network" means
"source-ip/source-prefix of the exporter"?.
BC> It means matching the flow records to a certain
prefix/AS/you-name-it, and exporting those matched flow records to an
exporter.
See for example, section 6.1 in RFC 6183
This could be explained better in the new section in
draft-ietf-ipfix-flow-selection-tech (See previous point)
The IESG has received a request from the IP Flow Information Export WG
(ipfix) to consider the following document:
- 'Flow Selection Techniques'
<draft-ietf-ipfix-flow-selection-tech-14.txt> as Proposed Standard
The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf(_at_)ietf(_dot_)org mailing lists by 2013-04-01. Exceptionally, comments
may be
sent to iesg(_at_)ietf(_dot_)org instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.
Abstract
Intermediate Flow Selection Process is the process of selecting a
subset of Flows from all observed Flows. The Intermediate Flow
Selection Process may be located at an IPFIX Exporter, Collector, or
within an IPFIX Mediator. It reduces the effort of post-processing
Flow data and transferring Flow Records. This document describes
motivations for using the Intermediate Flow Selection process and
presents Intermediate Flow Selection techniques. It provides an
information model for configuring Intermediate Flow Selection Process
techniques and discusses what information about an Intermediate Flow
Selection Process should be exported.
