At IETF= 73 I promised to look over draft-ietf-ippm-spatial-composition-07
and I have been doing so (somewhat slowly, but enjoying the read).

Althoug= h I haven't finished the whole draft yet,
I have amassed quite a few remarks, and think it best to split them up.
That way I can release the ones I already have,

and we can keep the threads separate.

This email will be on general topics and nits.

1) NIT = - the contributor list should not include the authors

2) The = whole idea of paths being subdivided into subpaths needs
   further clarification and most probably constaints.
   I will discuss this further in separate emails,
   but let me explain in a few words what I mean :
   A) Subpaths may be joined at a link or at a node;
      there are reasons for both
      (e.g. ITU recommends different operator doma= ins joining at a link,
      while border routers and PWE stitching point= s join at nodes.
      Note that when the joining is at a node the = end-to-end
      packet loss is the sum of the packet losses = in the pieces
      and that of the shared node, while when the = joining is at a link
      the end-to-end delay is the sum of the delay= s and that of the link.
      MEF studied some of the effects of this in a= n ad-hoc group
      called "accurate frame loss".
   B) There are frequently multiple paths between the endpoints.<= br>       These multiple paths can all be used in at l= east 3 cases
      i) rerouting events
      ii) ECMP/LAG
      iii) inverse mux.
      I don't know if these mechanisms have ever b= een seriously discussed
      in IPPM. Their effect is more general than t= he spatial composition case,
      but is particularly significant for this cas= e.

3) page= 5 - the use of spatial composition may also be the reverse.
If we know the end-to-end parameter, and that of all subpaths = but one,
then we can deduce that of the last path.

4) NIT = Section 4 - "The section is organized using the same subsections
   as the individual metrics ...". Yes, that WOULD have been= useful,
   but unfortunately sections 5.2 and 5.3 are missing the section=
   parallelling 4.1.4 "Statistic", thus e.g. 5.2.6 maps= to 4.1.7.

5) 5.1.= 2 (and other places) What is meant by "sufficiently LOW resolution&quo= t; ?
   At first I thought that this meant course resolution, but then= saw delays
   measured in microseconds. Does this actually mean "fine&q= uot; resolution ?
   Does the statement mean A) course resolution to be reproducibl= e OR
   B) fine resolution to be accurate ?

6) NIT = 5.2.2 (and other places). I am sure that you thought about this,
   but I find it confusing to use the index i to mean packet numb= er
   and afterwards the same index to mean subpath.
   I would like at least for the formula to say
   MeanDelay[i] =3D 1/N SUM_j=3D1^N FiniteDelay[i,j]
   where i =3D 1 to number_of_subpaths and j =3D 1 to number_of_p= ackets.
   A convention I frequently use in such cases would have
   the subpath index called "s" and have it run from 1 = to "S"
   and the packet index called "p" and have it run from= 1 to "P".

7) NIT = 5.2.5 - It would have been clearer to me to say that this composition
   means that the mean of the sum equals the sum of the means.    However, I admit to not understanding the caveat of the contin= ous distributions.
   When the paths contain a small number of nodes the distributio= ns will not
   be continuous at least at the bottom, since there will be a sh= arply defined
   minimum delay (this sharpness disappears with a large number o= f nodes
   since the sum of a large number of random variables starts loo= king Gaussian).
   In any case, it is not obvious to me that discontinuous distri= butions
   do not add correctly. Can you explain ?

8) 5.2.= 8 Another specific case would be when there is significant delay
   in a link connecting the subpaths
   For 5.3.8 another case would be when the delay depends on pack= et size
   and this packet size changes when going from subpath to subpat= h
   as a result of encapsulation changes.

That is= as far as I have gotten.
I will write up a few more emails on more in-depth remarks,
and add further short comments as I progress.

I copy it here, under the same licence as the original, for anyone who wants to play with it. It requires libxml2. To compile, on GNU/Linux-based systems: cc -DXML -lresolv $(xml2-config --cflags) $(xml2-config --libs) traceroute-nanog.c -o traceroute-nanog On FreeBSD, same thing without -lresolv. Then run it with -X to produce the XML output. After some tweaking of the XSD schema, the output validates. Attached are three examples of its output.

So, the reply will time out on the return path * (with no notice sent to anyone since icmp's aren't sent for * icmp's) until we probe with a ttl that's at least twice the path * length. I.e., rip is really only 7 hops away. A reply that * returns with a ttl of 1 is a clue this problem exists. * Traceroute prints a "!" after the time if the ttl is <= 1. * Since vendors ship a lot of obsolete (DEC's Ultrix, Sun 3.x) or * non-standard (HPUX) software, expect to see this problem * frequently and/or take care picking the target host of your * probes. * * Other possible annotations after the time are !H, !N, !P (got a host, * network or protocol unreachable, respectively), !S or !F (source * route failed or fragmentation needed -- neither of these should * ever occur and the associated gateway is busted if you see one). If * almost all the probes result in some kind of unreachable, traceroute * will give up and exit. * * Notes * ----- * This program must be run by root or be setuid. (I suggest that * you *don't* make it setuid -- casual use could result in a lot * of unnecessary traffic on our poor, congested nets.) * * This program requires a kernel mod that does not appear in any * system available from Berkeley: A raw ip socket using proto * IPPROTO_RAW must interpret the data sent as an ip datagram (as * opposed to data to be wrapped in a ip datagram). See the README * file that came with the source to this program for a description * of the mods I made to /sys/netinet/raw_ip.c. Your mileage may * vary. But, again, ANY 4.x (x < 4) BSD KERNEL WILL HAVE TO BE * MODIFIED TO RUN THIS PROGRAM. * * The udp port usage may appear bizarre (well, ok, it is bizarre). * The problem is that an icmp message only contains 8 bytes of * data from the original datagram. 8 bytes is the size of a udp * header so, if we want to associate replies with the original * datagram, the necessary information must be encoded into the * udp header (the ip id could be used but there's no way to * interlock with the kernel's assignment of ip id's and, anyway, * it would have taken a lot more kernel hacking to allow this * code to set the ip id). So, to allow two or more users to * use traceroute simultaneously, we use this task's pid as the * source port (the high bit is set to move the port number out * of the "likely" range). To keep track of which probe is being * replied to (so times and/or hop counts don't get confused by a * reply that was delayed in transit), we increment the destination * port number before each probe. * * Don't use this as a coding example. I was trying to find a * routing problem and this code sort-of popped out after 48 hours * without sleep. I was amazed it ever compiled, much less ran. * * I stole the idea for this program from Steve Deering. Since * the first release, I've learned that had I attended the right * IETF working group meetings, I also could have stolen it from Guy * Almes or Matt Mathis. I don't know (or care) who came up with * the idea first. I envy the originators' perspicacity and I'm * glad they didn't keep the idea a secret. * * Tim Seaver, Ken Adelman and C. Philip Wood provided bug fixes and/or * enhancements to the original distribution. * * I've hacked up a round-trip-route version of this that works by * sending a loose-source-routed udp datagram through the destination * back to yourself. Unfortunately, SO many gateways botch source * routing, the thing is almost worthless.

What a great idea! -P for parallel probing of * all TTLs. Messy on output if we don't want to sit * and definitely wait it out, but useful! -$ for the * old 'ping style' behavior. * 02/27/1999 V2.9.1 Allow more than one probe per hop, display last one to * successfully return. Fix so all packets returning will * override the max-wait timer. Fix so we check the TTL * and make sure our packets (even out of order) are ok. * pretty up the output. Remove magic number "3" for * ICMP_UNREACH_PORT. * 03/01/1999 V2.9.2 Freebsd seems to get packets that generate indices * which are outside the array (line 1299). This segfault * is corrected by a bounds check on line 1298. * 03/03/1999 V2.9.3 Make printing the header and time difference standard * callable routines (print_from, print_time). Make the * last address be a struct sockaddr_in instead of u_long * since that's the right way to do it. Make the code * in packet_ok() and send_probe() conditional on spray * mode so we don't jabber all over the data cells! * 09/30/1999 V2.9.4 Added "FORCE_NATURAL_MASK" in lookup_as() so that if * necessary, old-style lookups would still work. Now, * the -A option will use the address as is. * 11/15/1999 V6.0 Renumber to Version 6.0 and rename to TrACESroute * to avoid 'confusion' with vj/lbl traceroute 2.9.x. * Of course this makes us much more advanced than * Netscape 4.8, I.E. 5.0, or The New AOL 5.0. ;-) * 01/18/2000 V6.1 Dan Cohn provided mods to make * spray mode as functional as normal mode, both in * terms of missing packets and in multiple probes. * 04/29/2000 V6.1.1 As per Thomas Erskine, add info for -A where the * route is not in the RR server queried. * * 06/05/2001 V6.1.2 When using -A, get_origin() returns 0 for ASs not * found in your particular RA_SERVER. This, passed * to printf(%s) ended up as on Linux, and a * coredump on Solaris... fixed by adding a nullstring * and checking for zero result from get_origin. * Thanks to Richard Wright for pointing it out and * assisting in the debug. * 06/16/2001 emf_prototrace 0.2 * Added rudimentary support for generic protocol type * scan via -I option. It's really really rough right * now, but it gives me enough ammunition to tell * some feeb where my packets are stopping. I * generally use this with -I 50 to check for IPSec * VPN functionality. (You'd be completely amazed at * how many people claim their firewall isn't * interfering with their VPN clients. Sheesh) * * 10/27/2001 V6.1.3 Disallow max_ttl*nprobes>spraymax. Raise spraymax. * * 02/05/2002 V6.1.4 Simon Leinen provided some * nice code to check TOS changes in the encapsulated * header from its original value ... use -t TOS to set. * 04/12/2002 Updated comment above * * 07/23/2002 V6.2.0 Various sources report that the -T terminator can * be exploited to run malicious code. This is due * to sloppy coding on my part when writing it. * Fixed. In this version FIXT defines that code, and * assuming it works everywhere, will be mainline code * in the next minor release. * * 10/12/2002 V6.2.1 Daniel Kobras reports a slew of poor coding on * my part in get_origin(), as well as included Colin * Phipps code in one nice easy fun patch. Better * code for better living! * * 11/28/2002 V6.2.2 Benjamin Zwittnig from ARNES provided more fine * tuning of the accept logic on incoming ICMP packets * which reduces false results on machines with high * received ICMP traffic. Patch submitted by Simon * Leinen at Switch. * * 02/11/2003 V6.3.0 Three changes. First, Martin Godisch's patches * to allow this to run under Debian. Second, * Graeme Hewson's patches to fix ICMP traceroute, * and clean up preprocessor inefficiency. Finally, * add Terry Kennedy's fixes for broken raw ip. * * 02/24/2003 V6.3.2 Make MTU discovery work the RFC 1191 way. Also * make MTU discovery work on little endian machines. * Also makes -U actually terminate faster. * Code from and kudos to Graeme Hewson @oracle.com * * 03/10/2003 V6.3.3 Decode ICMP extension headers as per Jorge Boncompte, * who even supplied the decoding routine! * * 03/21/2003 V6.3.4 Jorge fixed the decoding for nonzero headers * * 03/31/2003 V6.3.5 Graeme provided misc bugfixes -- THANKS!!! * * * 05/22/2003 V6.3.6 Marco Steinacher points out some RAs delimit data * with tabs (0x09) instead of spaces (0x20). Fixed * get_origin ASN lookup code to also check for tabs. * * 07/07/2003 V6.3.7 Martin Godisch fixed automatic mode. * * 07/11/2003 V6.3.8 Martin Godisch provided a fix for Debian bug report * 200875 (Integer overflow). * * 07/15/2003 V6.3.9 Matt Zimmerman provided bugfixes * for same in Spray mode and other enhancements. * * 11/06/2005 V6.4.0 Georg Schwarz provided more bugfixes for sloppy code. * * 12/16/2005 V6.4.1 Added bounds checking on min_ttl and max_ttl * * 06/06/2006 V6.4.2 Changed nprobes to not be limited to SPRAYMAX if not * running in parallel mode, and prevent parallel mode * where nprobes >=SPRAYMAX with a warning to the user. * * 22/11/2008 unreleased Stephane Bortzmeyer added * support for generation of XML results, following the Internet-Draft * draft-ietf-ippm-storetraceroutes-12 */ #include #define IP_VERSION 4 /* We can't work with anything else... */ #define CISCO_ICMP 1 /* We check for loss+unreachables = probes */ #ifdef __decc /* DEC C wants strings.h to be called string.h */ #define STRING #define NOINDEX #define NOBZERO #endif #ifdef SOLARIS /* Solaris has UCB stuff gone, and POSIX resolver */ #define SUN_WO_UCB #define POSIX #endif #ifdef SUN_WO_UCB #define STRING #define NOINDEX #include #endif #ifdef _AIX /* Aix has its own set of fd_* macros */ #include #include #endif #ifdef STRING #include #else /* !

Henk - - - - Description of Working Group: The IPPM WG has developed a set of standard metrics that can be applied to the quality, performance, and reliability of Internet data delivery services. These metrics are designed such that they can be performed by network operators, end users, or independent testing groups. It is important that the metrics not represent a value judgment (i.e. define "good" and "bad"), but rather provide unbiased quantitative measures of performance. Functions peripheral to Internet data delivery services, such as NOC/NIC services, are beyond the scope of this working group. The IPPM WG has produced documents that define specific metrics and procedures for accurately measuring and documenting these metrics. This is the current list of fundamental metrics and the existing set of derived metrics. - connectivity - one-way delay and loss - round-trip delay. - delay variation - loss patterns - packet reordering - bulk transport capacity - link bandwidth capacity - packet duplication The working group will advance these metrics along the standards track within the IETF. It will be guided by applicable IESG documents in this area. Additionally, the WG will produce Proposed Standard AS documents, comparable to applicability statements in RFC 2026, that will focus on procedures for measuring the individual metrics and how these metrics characterize features that are important to different service classes, such as bulk transport, periodic streams, packet bursts or multimedia streams. Each AS document will discuss the performance characteristics that are pertinent to a specified service class; clearly identify the set of metrics that aid in the description of those characteristics; specify the methodologies required to collect said metrics; and lastly, present the requirements for the common, unambiguous reporting of testing results. The AS documents can also discuss the use of the metrics to verify performance expectations, such as SLA's, report results to specific user groups or investigate network problems. The focus is, again, to define how this should be done, not to define a value judgment. The WG may define additional statistics for its metrics if needed. Specific topics of these AS documents must be approved by the Area Directors as charter additions. The WG will work on documents describing how to compose and decompose the results of its metrics over time or space. The WG has produced protocols to enable communication among test equipment that implements the one- and two-way metrics (OWAMP and TWAMP respectively). OWAMP and TWAMP will be advanced along the standards track. Further development of these protocols will also be done inside the WG. The metrics developed by the WG were developed inside an active measurement context, that is, the devices used to measure the metrics produce their own traffic. However, most metrics can be used inside a passive context as well. No work is planned is this area though, this may be changed with AD approval. The intent of the WG is to cooperate with other appropriate standards bodies and forums (such as ATIS IIF, ITU-T SG 12, 13 and 15, MEF) to promote consistent approaches and metrics. Within the IETF process, IPPM metrics definitions will be subject to as rigorous a scrutiny for usefulness, clarity, and accuracy as other protocol standards. The IPPM WG will interact with other areas of IETF activity whose scope intersect with the requirement of these specific metrics. The WG will, on request, provide input to other IETF WG on the use of these metrics. -- ------------------------------------------------------------------------------ Henk Uijterwaal Email: henk.uijterwaal(at)ripe.net RIPE Network Coordination Centre http://www.amsterdamned.org/~henk P.O.Box 10096 Singel 258 Phone: +31.20.5354414 1001 EB Amsterdam 1016 AB Amsterdam Fax: +31.20.5354445 The Netherlands The Netherlands Mobile: +31.6.55861746 ------------------------------------------------------------------------------ Ceterum censeo Asplain esse delendam (Cato & Henk) _______________________________________________ ippm mailing list ippm@ietf.org https://www.ietf.org/mailman/listinfo/ippm From ippm-bounces@ietf.org Tue Dec 9 04:15:03 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 763FF28C10C; Tue, 9 Dec 2008 04:15:03 -0800 (PST) X-Original-To: ippm@ietf.org Delivered-To: ippm@core3.amsl.com Received: by core3.amsl.com (Postfix, from userid 0) id 60E0E3A6B0E; Tue, 9 Dec 2008 04:15:01 -0800 (PST) From: Internet-Drafts@ietf.org To: i-d-announce@ietf.org Content-Type: Multipart/Mixed; Boundary="NextPart" Mime-Version: 1.0 Message-Id: <20081209121501.60E0E3A6B0E@core3.amsl.com> Date: Tue, 9 Dec 2008 04:15:01 -0800 (PST) Cc: ippm@ietf.org Subject: [ippm] I-D Action:draft-ietf-ippm-duplicate-06.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: , Sender: ippm-bounces@ietf.org Errors-To: ippm-bounces@ietf.org --NextPart A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the IP Performance Metrics Working Group of the IETF. Title : A One-Way Packet Duplication Metric Author(s) : H. Uijterwaal Filename : draft-ietf-ippm-duplicate-06.txt Pages : 14 Date : 2008-12-09 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.

The sheperd note for this document is below. Let me know if you need anything else from us. Henk - - - - As required by RFC-to-be draft-ietf-proto-wgchair-doc-shepherding [rfc4858], this is the current template for the Document Shepherd Write-Up. Changes are expected over time. This version is dated September 17, 2008. Document shepherd writeup for draft-ietf-ippm-delay-var-as-01, as required by rfc4858, and specfied in the 17-Sep-2008 version of . (1.a) Who is the Document Shepherd for this document? Has the Document Shepherd personally reviewed this version of the document and, in particular, does he or she believe this version is ready for forwarding to the IESG for publication? The document shepherd is Henk Uijterwaal . I have personally reviewed this document and would not have bothered to write this not if I didn't feel it was ready for the IESG. (1.b) Has the document had adequate review both from key WG members and from key non-WG members? Does the Document Shepherd have any concerns about the depth or breadth of the reviews that have been performed? I believe the document has received sufficent review from key WG members (see acknowledgements for names). I don't believe there are key non-WG members that need to review the document. I have no concerns about the depth or breadth of reivews for this document. (1.c) Does the Document Shepherd have concerns that the document needs more review from a particular or broader perspective, e.g., security, operational complexity, someone familiar with AAA, internationalization or XML? No. (1.d) Does the Document Shepherd have any specific concerns or issues with this document that the Responsible Area Director and/or the IESG should be aware of? None. Has an IPR disclosure related to this document been filed? No. (1.e) How solid is the WG consensus behind this document? Does it represent the strong concurrence of a few individuals, with others being silent, or does the WG as a whole understand and agree with it? The WG asked for this document after a talk from Roman Krasnowski at IETF-65, the authors then voluntered to write it. It has been presented at a couple of meetings, received support and the authors have been thanked for writing the document as it is needed in day to day operations. The document has been reviewed in dept by about 5 members of the group. I have no indication that the majority of the WG members does not understand what this document is about. (1.f) Has anyone threatened an appeal or otherwise indicated extreme discontent? No. (1.g) Has the Document Shepherd personally verified that the document satisfies all ID nits? There are currently 4 nits: == It looks like you're using RFC 3978 boilerplate. You should update this, as the boilerplate described in the IETF Trust License Policy document (see http://trustee.ietf.org/license-info) is accepted from 10 November 2008, and will soon be required. Version 1.34 of xml2rfc can (when released) be used to produce documents with boilerplate according to the mentioned Trust License Policy document. I believe that this is a timing issue, the document was finished before the new boilerplate was. == The document doesn't use any RFC 2119 keywords, yet seems to have RFC 2119 boilerplate text. This reference can be removed by the editor. == Outdated reference: A later version (-07) exists of draft-ietf-ippm-framework-compagg-06 == Outdated reference: A later version (-07) exists of draft-ietf-ippm-spatial-composition-06 These are again timing issues. Has the document met all formal review criteria it needs to, such as the MIB Doctor, media type and URI type reviews? None of these are necessary. (1.h) Has the document split its references into normative and informative? Yes. Are there normative references to documents that are not ready for advancement or are otherwise in an unclear state? No. (1.i) Has the Document Shepherd verified that the document IANA consideration section exists and is consistent with the body of the document? There is an IANA considerations section. It is empty as the document doesn't require anything from the IANA. (1.j) Has the Document Shepherd verified that sections of the document that are written in a formal language, such as XML code, BNF rules, MIB definitions, etc., validate correctly in an automated checker? Not applicable. (1.k) The IESG approval announcement includes a Document Announcement Write-Up. Please provide such a Document Announcement Write-Up? Recent examples can be found in the "Action" announcements for approved documents. The approval announcement contains the following sections: Technical Summary Packet delay variation metrics appear in many different standards documents. The metric definition in RFC 3393 has considerable flexibility, and it allows multiple formulations of delay variation through the specification of different packet selection functions. Although flexibility provides wide coverage and room for new ideas, it can make comparisons of independent implementations more difficult. Two different formulations of delay variation have come into wide use in the context of active measurements. This memo examines a range of circumstances for active measurements of delay variation and their uses, and recommends which of the two forms is best matched to particular conditions and tasks. Working Group Summary Was there anything in WG process that is worth noting? For example, was there controversy about particular points or were there decisions where the consensus was particularly rough? This document was suggested after a talk on this topic at IETF-65. There was no controversy in the WG process. Consensus was smooth. Document Quality Are there existing implementations of the protocol? This document does not describe a new protocal. -- ------------------------------------------------------------------------------ Henk Uijterwaal Email: henk.uijterwaal(at)ripe.net RIPE Network Coordination Centre http://www.amsterdamned.org/~henk P.O.Box 10096 Singel 258 Phone: +31.20.5354414 1001 EB Amsterdam 1016 AB Amsterdam Fax: +31.20.5354445 The Netherlands The Netherlands Mobile: +31.6.55861746 ------------------------------------------------------------------------------ Ceterum censeo Asplain esse delendam (Cato & Henk) -- ------------------------------------------------------------------------------ Henk Uijterwaal Email: henk.uijterwaal(at)ripe.net RIPE Network Coordination Centre http://www.amsterdamned.org/~henk P.O.Box 10096 Singel 258 Phone: +31.20.5354414 1001 EB Amsterdam 1016 AB Amsterdam Fax: +31.20.5354445 The Netherlands The Netherlands Mobile: +31.6.55861746 ------------------------------------------------------------------------------ Ceterum censeo Asplain esse delendam (Cato & Henk) _______________________________________________ ippm mailing list ippm@ietf.org https://www.ietf.org/mailman/listinfo/ippm From lgobstacle@amlwireless.com Wed Dec 10 06:54:26 2008 Return-Path: X-Original-To: ietfarch-ippm-archive@core3.amsl.com Delivered-To: ietfarch-ippm-archive@core3.amsl.com Received: from localhost (localhost [127.0.0.1]) by core3.amsl.com (Postfix) with ESMTP id C501E3A6BB0 for ; Wed, 10 Dec 2008 06:54:26 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -4.086 X-Spam-Level: X-Spam-Status: No, score=-4.086 tagged_above=-999 required=5 tests=[BAYES_99=3.5, FH_RELAY_NODNS=1.451, HTML_FONT_LOW_CONTRAST=0.124, HTML_IMAGE_ONLY_08=1.787, HTML_MESSAGE=0.001, HTML_SHORT_LINK_IMG_1=0.001, MIME_HTML_ONLY=1.457, RAZOR2_CF_RANGE_51_100=0.5, RAZOR2_CF_RANGE_E8_51_100=1.5, RAZOR2_CHECK=0.5, RCVD_IN_BL_SPAMCOP_NET=1.96, RCVD_IN_XBL=3.033, RDNS_NONE=0.1, URIBL_AB_SURBL=10, URIBL_BLACK=20, URIBL_JP_SURBL=10, URIBL_SBL=20, URIBL_SC_SURBL=10, URIBL_WS_SURBL=10, 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 HCJS1fZPWkQu for ; Wed, 10 Dec 2008 06:54:26 -0800 (PST) Received: from ais.co.th (unknown [189.84.241.5]) by core3.amsl.com (Postfix) with SMTP id 264A73A6BAF for ; Wed, 10 Dec 2008 06:54:21 -0800 (PST) To: Subject: RE: Message From: MIME-Version: 1.0 Importance: High Content-Type: text/html Message-Id: <20081210145423.264A73A6BAF@core3.amsl.com> Date: Wed, 10 Dec 2008 06:54:21 -0800 (PST)

If the user is presented with: Speech level = -7 dBm0 this is not intuitively understandable, unless the user is a telephony expert. If the metric definition explains that the typical range is -18 to -28 dBm0, a value higher than -18 means the signal may be too high (loud) and less than -28 means that the signal may be too low (quiet), it is much easier to interpret the metric. If the typical range is -18 to -28, then I still have a problem to interpret -7 (outside the range). I'd also add that this is a logarithmic scale. Other than that, yes, I've read this and read it again, it still looks fine.
