Dear Benoit,
Will do. Kind regards, Salvatore Da: Benoit Claise [mailto:bcla...@cisco.com] Inviato: mercoledì 20 marzo 2013 09:36 A: draft-ietf-ipfix-flow-selection-t...@tools.ietf.org Cc: IETF-Discussion list; Rahul Patel; ip...@ietf.org Oggetto: Re: [IPFIX] Last Call: <draft-ietf-ipfix-flow-selection-tech-14.txt> (Flow Selection Techniques) to Proposed Standard 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. 1. Also in the example " e.g., Filtering only 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@ietf.org mailing lists by 2013-04-01. Exceptionally, comments may be sent to i...@ietf.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.
