Currently switchs and routers analyse flows and export flow information using Netflow. Aggregators are starting to use Netflow or IPFIX to collect basic information and to export aggregated information. In this context, this memo presents potential interoperability issues and proposes to standardize a set of templates to facilitate the exchange of flows and measurements information between ISP.

Network traffic=20 measurements are invaluable for a wide range of tasks such as network=20 capacity planning, traffic engineering, fault diagnosis, application=20 and protocol performance profiling, and anomaly detection. This large and diverse set of applications raises the question of=20 how to monitor the Internet in an efficient and scalable way. In the=20 case of active monitoring (where probe packets are sent across the=20 network to infer specific properties) the scalability issue arises=20 from the size of the Internet and the potentially large number of=20 end systems that one needs to instrument, as well as the number of=20 probing experiments that one must conduct. Intuitively, sampling is an essential component of scalable Internet monitoring. Broadly speaking, sampling is the process of making=20 partial observations of a system of interest, and drawing conclusions=20 about the full behaviour of the system from these limited observations.=20 The observation problem is concerned with minimising information loss=20 whilst reducing the volume of collected data. It is this reduction=20 that makes the collection process scalable. The way in which the=20 partial information is transformed into knowledge of the system as=20 a whole is the inversion problem. The inversion is in general=20 imperfect and error-prone. The aim of this issue is to bring together work from researchers=20 and practitioners devoted to the understanding of the practical and=20 theoretical issues related to all aspects of sampling the Internet.=20 In this context, sampling may take various forms. A classic example=20 is to observe only a subset of the packets carried over a link, and then estimate traffic parameters which apply to all packets.=20 Alternatively, one could target a subset of routers with packet=20 probes in order to infer network characteristics such as the=20 topology or routing matrix.=20 Examples abound from a wide variety of application areas within=20 Internet measurement, management, and analysis. Independent of=20 subject area, papers will be in scope if they focus substantially=20 on the sampling aspects of the problem under study, for example by=20 exploring the tradeoff between observation and inversion processes,=20 revealing the limitations of inversion techniques, analysing their=20 properties, or proposing new ones, or by providing new insights by=20 explicitly recognizing the impact of implicit sampling in many=20 measurement studies. Topics of interest include (but are not limited to): - Sampling and inverting traffic metrics with passive or active systems. - Internet end-to-end measurements seen from a sampling standpoint. - Sampling aspects of network topology inference. - Impact of sampling on anomaly detection. - Mechanisms for sampling live Internet traffic or collected traces. - Theoretical studies of the sampling/inversion problem=20 (e.g., accuracy, complexity). - Distributed and adaptive sampling techniques. - New sampling methods. Submission guidelines Authors should follow the IEEE J-SAC manuscript format described=20 in the Information for Authors. There will be one round of reviews=20 and acceptance will be limited to papers needing only moderate = revisions.=20 Prospective authors should submit a PDF version of their complete=20 manuscript via email to jsac-sampling at sophia.inria.fr according to=20 the following timetable:=20 Manuscript submission: October 1, 2005 Acceptance notification: March 1, 2006 Final manuscript due: June 1, 2006 Publication: 4th quarter 2006 Guest Editors =20 Chadi Barakat INRIA Plan=E8te group 2004, route des Lucioles 06902 Sophia Antipolis France Chadi.Barakat at sophia.inria.fr Gianluca Iannaccone Intel Research 15 JJ Thomson Avenue Cambridge CB3 0FD United Kingdom gianluca.iannaccone at intel.com Jim Kurose Department of Computer Science =20 University of Massachusetts =20 Amherst MA 01003=20 United States kurose at cs.umass.edu=20 Darryl Veitch CUBIN (ARC Special Research Ctr) Department of Electrical & Electronic Engineering University of Melbourne Victoria 3010 Australia dveitch at unimelb.edu.au _______________________________________________ ippm mailing list ippm@ietf.org https://www1.ietf.org/mailman/listinfo/ippm From ippm-bounces@ietf.org Thu Jul 28 06:56:29 2005 Received: from localhost.localdomain ([127.0.0.1] helo=megatron.ietf.org) by megatron.ietf.org with esmtp (Exim 4.32) id 1Dy63x-00087B-No; Thu, 28 Jul 2005 06:56:29 -0400 Received: from odin.ietf.org ([132.151.1.176] helo=ietf.org) by megatron.ietf.org with esmtp (Exim 4.32) id 1Dy63v-00086r-Fu for ippm@megatron.ietf.org; Thu, 28 Jul 2005 06:56:27 -0400 Received: from ietf-mx.ietf.org (ietf-mx [132.151.6.1]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id GAA15562 for ; Thu, 28 Jul 2005 06:56:24 -0400 (EDT) Received: from basie.internet2.edu ([207.75.164.22]) by ietf-mx.ietf.org with esmtp (Exim 4.43) id 1Dy6ZM-0000eB-DW for ippm@ietf.org; Thu, 28 Jul 2005 07:28:57 -0400 Received: from localhost (unknown [127.0.0.1]) by basie.internet2.edu (Postfix) with ESMTP id 89CE41CD82C; Thu, 28 Jul 2005 06:56:20 -0400 (EDT) Received: from basie.internet2.edu ([127.0.0.1]) by localhost (basie.internet2.edu [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 30336-09; Thu, 28 Jul 2005 06:56:20 -0400 (EDT) Received: from localhost (unknown [127.0.0.1]) by basie.internet2.edu (Postfix) with ESMTP id 3BC211CD807; Thu, 28 Jul 2005 06:56:20 -0400 (EDT) Date: Thu, 28 Jul 2005 06:56:18 -0400 From: Matthew J Zekauskas To: ippm@ietf.org Message-ID: <1E1E89FE72A0FDD967056BCC@DCFF15AFC1F6764BA3927E50> X-Mailer: Mulberry/4.0.0 (Win32) MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: quoted-printable Content-Disposition: inline X-Virus-Scanned: by mail.internet2.edu virus scanner X-Spam-Score: 0.0 (/) X-Scan-Signature: 97adf591118a232206bdb5a27b217034 Content-Transfer-Encoding: quoted-printable Cc: Henk Uijterwaal , Matt Zekauskas Subject: [ippm] Draft ippm Paris agenda X-BeenThere: ippm@ietf.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: IETF IP Performance Metrics Working Group List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Sender: ippm-bounces@ietf.org Errors-To: ippm-bounces@ietf.org The IPPM group will meet on Monday August 1, 10:30 in Paris.

Got some comments here. The inaccuracy might be also caused by interdomain routing choices additional to the intro-domain ones. Doing the sub-path measurement for each domain might conceal the complete path when there are multipath to choose from the source to the final destination via several domains. for example, the packet can go to the final destination via domain 1, 2 to 3. it may also travel through domain 1, 4 to 3. Therefore, the sub-measurement carried out at the same time interval does not solve the path problem. Also, the gateway functions between domains may also address inaccuracy. E.g., multiplexing, translation, deconding and encoding will all put costs to the complete measurement result. I also got a question here that you might help. Why don't just send the packets from the source to the final destination and collect the sub-path results on the way?

We (the authors of draft-jayasumana-reorder-density-04.txt ) will not be able to make a presentation at the meeting. However, the wonderful thing about ietf is the ability to present your views even when you are unable to attend the meetings. So, we would once again like to drive our point of comparison between the metrics. Here are links to a document in both pdf and ps, which contains comparison between the metrics. This document also contains reordering measurements over the Internet, using various metrics.
