One clarification about the SERVWAIT time. I believe the receipt of test packets should ONLY be covered by REFWAIT and that a Server should be notified by the Reflector of such a timeout, so I would change the paragraph under 3.1 From ==== The Server MAY discontinue any established control connection when no packet associated with that connection, AND no packet associated with any test sessions started by that control connection have been received for SERVWAIT seconds. To == The Server MAY discontinue any established control connection when no packet associated with that connection has been received within SERVWAIT seconds prior to transitioning into active state. A Stop-Sessions packet MAY arrive at any length of time after the active state has been entered. The reason is that once an active state has been entered all packets except for Stop-Sessions is to be discarded. But inactivity before the active state transition should result in the connection being closed. Also, there are some minor spelling errors.

There seems to be a problem with the spell-check in this MSWord template - parts of the doc are not checked. I'll try something else. Now on to the more important comment. Murtaza wrote: > One clarification about the SERVWAIT time.

Perhaps it makes for a simpler implementation, too. With either your proposal or the current description in the text, the SERVWAIT process needs to know which phase is active, control or test. And, between the START and STOP sessions commands, control packet monitoring for SERVWAIT is suspended. But if the current SERVWAIT covers problems during control or test phases, do we really need REFWAIT? Only if the *WAIT thresholds will be set at different values, which I think is a reasonable possibility. So, how about this replacement text: The Server MAY discontinue any established control connection when no packet associated with that connection has been received within SERVWAIT seconds. The Server SHALL suspend monitoring control connection activity after receiving a Start-Sessions command, and SHALL resume after receiving a Stop-Sessions command (IF the SERVWAIT option is supported). Note that the REFWAIT time-out (described below) covers failures during test sessions.

Some comments, reading this as a non-expert on GMPLS. 3.4. Units. I don't think this is quite correct: you start to measure at T1 and wait for the setup to complete. However, it doesn't, so at some point you become bored and stop the measurement. You report undefined. However, one then has to report in the metrics parameters when the measurement will be stopped. This value should be added to the metrics parameters. (Note: this will apply to more metrics). 4.3. Metrics Parameters. In IPPM speak, Lamba refers to a rate but it also specifies a distribution for the interval between probe packets. For example, poisson or periodic. The draft should mention which distribution to use. 12.1. Statistics. I think you better report the 5th or 10th percentile of the distributions, rather than the minimum (and the same for the maximum). This excludes data points where something went wrong in the measurement process.

The authors would now like to solicit comments among the performance metric experts, as this document contains notations that are commonly seen in IPPM and BMWG. The authors believe that your expertise can help us further improve this document, with regard to the definition of the metrics and the structure as well. Please send your comments directly to the authors, or, to the CCAMP working group mail list (ccamp@ops.ietf.org). We do appreciate your input.

As I've said in the past, this draft is an excellent start,
and because it adopts the metric template used in bmwg and ippm,
it's an easy read. Thanks for doing that part.

General comments:
-----------------
There is a taxonomy of possible outcomes for set-up protocols.
Each set-up attempt will have one of the following outcomes:

1. Success
2. Failure
3. Incorrect Set-up (wrong destination)

The same basic outcomes apply to release attempts.

In the current text, the set-up time metrics cover the
Successful outcome (they could be called Successful *.* Setup Time).

When a setup attempt fails, the setup time is Undefined. Stop there.
Please remove the "informally infinite" phrase between
parentheses, because it places the failure outcome on the
same dimension as success. As I've pointed out above,
the 3 outcomes are mutually exclusive.  I know this text came
from IPPM RFCs, but this is a case where you should not follow
that precedent, IMHO.  For more nit-picking background, read
http://tools.ietf.org/id/draft-morton-ippm-reporting-metrics-05.txt

Back to the Failure Outcome.  I can imagine that there will be
technologies for which a metric on Setup Failure Ratio may be
more important than the Successful setup time - I may not care
if the setup takes 1 second or 10 seconds, but the 50% failure
ratio is annoying...

So, I propose to add metrics to cover the Failure outcome,
defined as a count of failures=Undefined setup times divided by the
total attempts. This would be a single outcome for a singleton
metric and a ratio for metrics with multiple LSP setups.
(I saw the metric in 12.4, it doesn't quite have the right wording
or emphasis - this metric should be a part of all setup and release
scenarios).

Adding metrics to cover the Incorrect setup/release outcome
would complete the taxonomy.  I can accept that the Incorrect
outcome may be quite rare in practice, but having the metric
defined and ready is a reasonable use of resources. You can
note that these outcomes may be rare in some technologies as
part of the discussion.

Specific Comments:
------------------
(You can generalize these to all applicable sections)

3.3  Metric Parameters

  o  ID0, the ingress LSR ID

  o  ID1, the egress LSR ID

You should use these ID#s in the definition of the metric.

  o  T, a time

I've found that the two word description of a parameter is
not always sufficient for me.  I suggest:

  o  T, a time when the setup is attempted

I suggest to add a parameter, for clarity:

  o  WAITTIME, the maximum waiting time for successful setup

and mention this parameter in the sections where discussed,
like 3.5 and 3.6.

----------

13. Discussion

The control-plane-only nature of these metrics should be clear(er)
in the Introduction/Scope.

Question:
How important is it to have data-plane verification of the
apparent control-plane success/failure/incorrect performance?

This draft is a work item of the IP Performance Metrics Working Group of the IETF. Title : Information Model and XML Data Model for Traceroute Measurements Author(s) : S. Niccolini, et al. Filename : draft-ietf-ippm-storetraceroutes-10.txt Pages : 70 Date : 2008-06-06 This document describes a standard way to store the configuration and the results of traceroute measurements. This document first of all describes the terminology used in this document and the traceroute tool itself; afterwards, the common information model is defined dividing the information elements in two semantically separated groups (configuration elements and results ones).

This draft is a work item of the IP Performance Metrics Working Group of the IETF. Title : A Two-way Active Measurement Protocol (TWAMP) Author(s) : J. Babiarz Filename : draft-ietf-ippm-twamp-08.txt Pages : 25 Date : 2008-6-9 The One-way Active Measurement Protocol [RFC4656] (OWAMP) provides a common protocol for measuring one-way metrics between network devices. OWAMP can be used bi-directionally to measure one-way metrics in both directions between two network elements. However, it does not accommodate round-trip or two-way measurements. This memo specifies a Two-way Active Measurement Protocol (TWAMP), based on the OWAMP, that adds two-way or round-trip measurement capabilities. The TWAMP measurement architecture is usually comprised of two hosts with specific roles, and this allows for some protocol simplifications, making it an attractive alternative in some circumstances.

It has now reached a stable state again. The following changes have been made (with big support from Pasi): * Did improve the XML Schema for better readability and less duplication. * Adjusted description of test name, because the uniqueness is much more relaxed than in RFC4560. * Made the CtlTypes extendable as proposed by Pasi. * Added a reference for setsockopt (IEEE.1003.1G). * Aligned ProbeResult history with RFC4560, which implies an adjustment of the range. * All Metadata elements are now required but have a default. This is due to the improved XML Schema that tries to avoid to define the same things twice. You are required to specify all Metadata elements also in the request but can put them as empty elements () thus using the default value which would have been done anyway (by the application) when you omit an optional element. * Adjusted the inetAddress XML types and their usage also to improve readability and simplify the schema. * Aligned the _roundTripTime type with RFC4560. * Added HopName to store the DNS name of HopAdress if available. This was done due to the fact that DNS names may change over time. So you get the HopAddress (IP) and the HopName which is the DNS name that matched the HopAddress at the time of execution. * Added a bunch of examples. * Fixing number of ProbeResults per Measurement which should be exactly one. * Aligning description of draft and schema which drifted a little bit apart due to the many changes first made in the XML schema. * Aligning default values with RFC4560, those that I missed in the first shot. * Reviewing and updating Appendix C which describes the relation to RFC4560. I hope this has put the draft into a good shape and we can continue the process.

After the draft was submitted to the IESG, the GEN-ART review team provided us with extensive feedback on the XML part of the document. All suggestions have been incorporated, please refer to Thomas Dietz' mail of June 12 for a full overview of changes made. The changes improve the XML code but do not change the intent of the code. Nevertheless, we feel that it is good if the group reviewed the document once more before it is sent to the IESG. We like to start a WGLC on it in order to move it forward.

Session 1: Ongoing work ======================= In this session, we'll discuss the items that we are currently working on. So-far, I have as agenda topics: * Status of drafts, milestones, etc. * TWAMP extensions/Al & Kaynam * Delay Variation AS/Al * .... Other topics are welcome. Session 2: BoF on future work for the group =========================================== In Philadelphia, we discussed the future of the group now that we get close to finishing the work that is on our plate. We had some discussion on possible future work items. In Philly, people did suggest to have a BoF to discuss this in Dublin. This BoF has been approved and we should now start to put an agenda together: 1. Administrative details. 2. What did IPPM do so-far (Henk/Matt). 3. Possible future work items. a) SLA validations = ... b) Passive measurements = ... c) Comparison of Metrics = ... d) Other possible work items 4. Discussion. 5. How to proceed from here. If you have work that fits into section 3, please let me know and I'll give you a slot on the agenda. However, note that the goal of the BoF is to determine if there are problems that needs to be solved _and_ there is a critical mass of people who want to work on this. The goal of the BoF is NOT to discuss possible solutions in great detail.

Henk, I have a few wording suggestions, but otherwise I think this is ready to go. Al Section 1, last bullet: > o Finally, a method to summarise the properties of these samples are > introduced. The last aspect introduced is "statistics" (our framework is singletons, samples, statistics) so I suggest: o Finally, statistics that summarize the properties of these samples are introduced. Section 1.2, 2nd para > In earlier work, the IPPM (IP Performance Metrics) group defined a > metric for packet loss [RFC2680]. This metric quantifies the case > where a packet that is sent, never arrives at its destination. In > this memo, a metric for the opposite case is defined: a packet is > sent, but multiple copies arrive. I have a couple of quibbles with this, the definition of a lost packet and the fact that there are three possible outcomes in the taxonomy of arrivals. I'll just write what I mean: In earlier work, the IPPM (IP Performance Metrics) group defined a metric for packet loss [RFC2680]. This metric distinguishes the outcome where a transmitted packet does not arrive at its destination within a reasonable time from the arrival outcome. In this memo, a metric for yet a third outcome is defined: a single packet is sent and multiple copies arrive. Section 2.2 Metric_ Parameters As I said on the LSP set memo, I think that more description of the time parameters is helpful: > o T, a time > o T0, a time I suggest: o T, the wire time of a packet at the source o T0, the maximum waiting time for a packet to arrive at the destination Section 2.4 Definition > Two packets are considered identical when were sent by one and the > same host and contain identical information fields. The recipient > thus could take either packet and use it in an application, the other > copy would not contain any additional information. > > The IP headers do not necessarily have to be identical. I suggest: Two packets are considered identical if and only if: + both were sent by one and the same host + both contain identical information fields + both contain valid, but not necessarily identical IP header fields I saw some other minor editing opportunities, but I'm out of time to type them up tonight. _______________________________________________ ippm mailing list ippm@ietf.org https://www.ietf.org/mailman/listinfo/ippm From ippm-bounces@ietf.org Wed Jun 25 19:30:10 2008 Return-Path: X-Original-To: ippm-archive@megatron.ietf.org Delivered-To: ietfarch-ippm-archive@core3.amsl.com Received: from [127.0.0.1] (localhost [127.0.0.1]) by core3.amsl.com (Postfix) with ESMTP id F385228C134; Wed, 25 Jun 2008 19:30:09 -0700 (PDT) X-Original-To: ippm@core3.amsl.com Delivered-To: ippm@core3.amsl.com Received: from localhost (localhost [127.0.0.1]) by core3.amsl.com (Postfix) with ESMTP id D930128C134 for ; Wed, 25 Jun 2008 19:30:08 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -104.369 X-Spam-Level: X-Spam-Status: No, score=-104.369 tagged_above=-999 required=5 tests=[AWL=-1.427, BAYES_00=-2.599, HTML_MESSAGE=0.001, MIME_HTML_ONLY=1.457, MIME_QP_LONG_LINE=1.396, MSGID_FROM_MTA_HEADER=0.803, RCVD_IN_DNSWL_MED=-4, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([64.170.98.32]) by localhost (core3.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id wqz7TIJ+ldUo for ; Wed, 25 Jun 2008 19:30:08 -0700 (PDT) Received: from mail121.messagelabs.com (mail121.messagelabs.com [216.82.245.115]) by core3.amsl.com (Postfix) with ESMTP id D869828C0E1 for ; Wed, 25 Jun 2008 19:30:07 -0700 (PDT) X-VirusChecked: Checked X-Env-Sender: acmorton@att.com X-Msg-Ref: server-11.tower-121.messagelabs.com!1214447408!18099809!1 X-StarScan-Version: 5.5.12.14.2; banners=-,-,- X-Originating-IP: [144.160.128.141] Received: (qmail 7225 invoked from network); 26 Jun 2008 02:30:09 -0000 Received: from sbcsmtp9.sbc.com (HELO flph161.enaf.ffdc.sbc.com) (144.160.128.141) by server-11.tower-121.messagelabs.com with AES256-SHA encrypted SMTP; 26 Jun 2008 02:30:09 -0000 Received: from enaf.ffdc.sbc.com (localhost.localdomain [127.0.0.1]) by flph161.enaf.ffdc.sbc.com (8.14.2/8.14.2) with ESMTP id m5Q2U8pC002233 for ; Wed, 25 Jun 2008 19:30:08 -0700 Received: from klph001.kcdc.att.com (klph001.kcdc.att.com [135.188.3.11]) by flph161.enaf.ffdc.sbc.com (8.14.2/8.14.2) with ESMTP id m5Q2U2HT002206 for ; Wed, 25 Jun 2008 19:30:03 -0700 Received: from kcdc.att.com (localhost.localdomain [127.0.0.1]) by klph001.kcdc.att.com (8.14.0/8.14.0) with ESMTP id m5Q2U2aQ013618 for ; Wed, 25 Jun 2008 21:30:02 -0500 Received: from maillennium.att.com (dns.maillennium.att.com [135.25.114.99]) by klph001.kcdc.att.com (8.14.0/8.14.0) with ESMTP id m5Q2TxEh013556 for ; Wed, 25 Jun 2008 21:29:59 -0500 Message-Id: <200806260229.m5Q2TxEh013556@klph001.kcdc.att.com> Received: from acmt.att.com (unknown[135.210.73.182](misconfigured sender)) by maillennium.att.com (mailgw1) with SMTP id <20080626022957gw100l7o9pe>; Thu, 26 Jun 2008 02:29:58 +0000 X-Mailer: QUALCOMM Windows Eudora Version 7.1.0.9 Date: Wed, 25 Jun 2008 22:29:55 -0400 To: Matthew J Zekauskas , IETF IPPM WG , Henk Uijterwaal From: Al Morton In-Reply-To: <4862F437.706@internet2.edu> References: <4862F437.706@internet2.edu> Mime-Version: 1.0 Cc: Matt Zekauskas Subject: Re: [ippm] comments on draft-ietf-ippm-duplicate-03.txt X-BeenThere: ippm@ietf.org X-Mailman-Version: 2.1.9 Precedence: list List-Id: IETF IP Performance Metrics Working Group List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: multipart/mixed; boundary="===============1288619769==" Sender: ippm-bounces@ietf.org Errors-To: ippm-bounces@ietf.org --===============1288619769== Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable At 09:43 PM 6/25/2008, Matthew J Zekauskas wrote:

I don't think it's as stringent as with one-way delay... I tried to do this with "uniquely determine the interval [T, T+T0] at both sides". If one looks at T0, then one gets an idea how accurate the synchronization should be. If T0 is, say, 1 day, then seconds or minutes synchronization should be fine. If T0 is, say, 1 second, then you need far better synchronization. I don't want put a number in here. but I'm open for better wording.

This draft is a work item of the IP Performance Metrics Working Group of the IETF. Title : IP Performance Metrics (IPPM) for spatial and multicast Author(s) : E. Stephan, et al. Filename : draft-ietf-ippm-multimetrics-07.txt Pages : 50 Date : 2008-06-26 The IETF IP Performance Metrics (IPPM) working group has standardized metrics for measuring end-to-end performance between two points. This memo defines two new categories of metrics that extend the coverage to multiple measurement points. It defines spatial metrics for measuring the performance of segments of a source to destination path, and metrics for measuring the performance between a source and many destinations in multiparty communications (e.g., a multicast tree).Requirements Language The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].

Thinking about this longer: it probably isn't. Suppose we have a path: source, intermediate devices, destination. The source sends one packet, an intermediate device duplicates it, destination gets two copies. This is duplication, but it fails the definition above. So, I'd rephrase it into: + both appear to have been sent by one and the same host, to one and the same destination This covers the case above.

High-level bit: Ready for publication, after we've clarified exactly which packet header fields need to be compared to determine duplication. Lars Detailed comments: INTRODUCTION, paragraph 14: > In earlier work, the IPPM (IP Performance Metrics) group defined a > metric for packet loss. This metric quantifies the case where a > packet that is sent, never arrives at its destination. Nit: Rephrase to talk about RFC2680 rather than about the IPPM WG (published docs should avoid referring to WGs, because they are ephemeral). Section 2.4., paragraph 1: > Two packets are considered identical when were sent by one and the > same host and contain identical information fields. The recipient > thus could take either packet and use it in an application, the other > copy would not contain any additional information. > The IP headers do not necessarily have to be identical. Related to the ongoing discussion about this on the mailing list, I agree that we need to clearly defined which fields of the IP header are compared to detect duplicates across a set of packets. Source and destination IP address, length, next header/protocol, IP ID (for IPv4), flow label (for IPv6), IP version and DSCP?

This draft is a work item of the IP Performance Metrics Working Group of the IETF. Title : A One-Way Packet Duplication Metric for IPPM Author(s) : H. Uijterwaal Filename : draft-ietf-ippm-duplicate-04.txt Pages : 14 Date : 2008-6-30 When a packet is sent from one host to the other, one normally expects that exactly one copy of the packet that was sent arrives at the destination. It is, however, possible that a packet is either lost or that multiple copies arrive. In earlier work a metric for packet loss has been defined. This metric quantifies the case where a packet that is sent, does not arrive at its destination within a reasonable time. In this memo, a metric for another case is defined: a packet is sent, but multiple copies arrive. The document also discusses streams and methods to summarize the results of streams.

I'm not convinced that this text will lead to implementations that will come up with the same measurement results for the same packet sequence. Can we be more precise? > Two packets are considered identical if and only if: > > o Both contain identical information fields. The recipient thus > could take either packet and use the data in an application. > The > other packet does not contain any additional information. > o Both packets appear to have been sent by one and the same > host, to > one and the same destination. Host are identified by their IP > addresses. > o Both contain valid, but not necessarily identical IP header > fields.
