Based on its design, the Porsche Design Company developed an appealing, stylish, sporty and highly accurate watch. Unfortunately, these timepieces come with a high price tag. http://www.deoospl.com/ That's why a clever group of European manufacturers decided to offer the same exact functionality and style at greatly reduced prices: the Porsche Design replica watches. These replicas are so similar to the brand name pieces that it is practically impossible to tell them apart, other than by their price. They look the same, they function the same and they definitely don't have the same prices :) How would you like to browse through an amazing collection of these watches and marvel yourself with their low prices?

We could also handle apparent failures by allowing the Server and
Session Reflector to time-out and free-up resources after a
period on zero activity.  Since adding this behavior requires
no message changes, it's easier and less disruptive right now...

-Murtaza

If TWAMP is embedded in a router or a switch, the TWAMP spec
only covers the TWAMP functions.  Other configurations cover
the treatment of DSCP, if any.

revised text is on the way...

This does seem to be an implementation detail.
I imagine that at least one of the ports needs to change
for each test session.

(Al) If this is a big deal for some specific application,
I would suggest setting up two control connections (for now),
and extend the commands to start/stop individual sessions
in future.

The other thing is how would one define zero activity?   The Server has no knowledge when a Stop message should arrive!

I suggest a wording like this:

   ...The Session-Reflector MAY
  discontinue any session which has been Started when no packet
  associated with that session has been received for REFWAIT seconds.
  The default value of REFWAIT SHALL be 900 seconds, and this waiting
  time MAY be configurable.

This applies on a single session basis, which seems to be
something you want...

We had some discussion on possible future work items: = Passive measurements = SLA Monitoring = Comparision of metrics. I may have forgotten something (and I'm not sitting near the minutes, so I can't check). The first two items aren't covered by our current charter, so if we'd want to work on them, we need to recharter. In Philly, people did suggest to have a BoF to discuss this in Dublin. The cut-off date to requests BoF is about two weeks from today, so, if you still feel like this, please drop us a note to confirm your interest. It'd be even better if you could add a few lines that can be included in the BoF proposal. Alternatively, if you feel that we can do this with rechartering, please say so, again with text for the new charter more than welcome. Deadline for all this is about a week from today, May 20, so we have some time to put a request together.

Sorry, this got stuck in my mailbox, mainly because I don't quite understand what the problem is here. I still don't :-) so I'm probably missing something... Now, suppose I measure something with probes. I get 10,000 events, then bin them to get an idea of the distribution. This gives me a median and percentiles. If I then repeat this by sampling 100,000 times, then I simply expect 10x as many events in each bin, but I don't expect the distribution and thus the median to change. In other words, my curves will be a bit smoother, but the overall result won't change much.

The last sentence adresses the point, that there is a deviation - = so the metric comparism standard would have to define = how to compare samples of different sizes (I guess statisticians = can provide literature on this). If all sample sizes are the same = and if the sample function is the same, then you directly can = compare results. In other words: samples of different size produce results with = different errors. This error should be visible in an evaluation to = indicate, whether results are compatible or not. I've done some of these comparisms with regard to packet loss, = starting from a CBR probe distance of 200 ms and ending at a probe = distance of one per minute, always using the same basic set of = measurement data. The experiment had the aim to figure out, which = minimum sample size is required to measure a loss period correctly. And there are sample sizes, when the means start to deviate = significantly. So I repeat my point of view: don't ignore the impact of the = sample size if two measurement systems to be compared don't work = with the same. My proposal: Always try to make the sample sizes = the same (which should be possible with or requires respectively access to raw data of the measurement results). = Regards, Rudiger | -----Original Message----- | From: Henk Uijterwaal [mailto:henk@ripe.net] = | Sent: Tuesday, May 13, 2008 3:07 PM | To: Geib, R=FCdiger | Cc: ippm@ietf.org | Subject: Re: Comparism of metrics | = | Hi Rudiger, | = | > there has been no discussion on the list since while and I assume = | > comparing metrics still is an open issue. | = | Yes. | = | > A point I was concerned | > about is how to compare probes of different probe sizes (say one of = | > 100 000 probes measured with system 1 as compared to one of 10 000 = | > probes measured by system 2 during the same time interval T).

If the mailing list members get some interests, we want to discuss about the I-Ds in Dublin. draft-kikuchi-passive-measure-01.txt draft-kikuchi-tunnel-measure-req-02.txt We have tried to define some kinds of metrics and a method of passive measurement in the former I-D, based on the requirements written in the latter I-D. (The latter one had expired in a few days ago, sorry for inconvenience) The latter I-D originally states the requirements of passive measurement of tunnels though, it may adapt to other transports.

Its appeal comes from their traditional beauty and their superb performance. But this sophistication has always come with a high price tag. Except of course, when you buy an IWC replica. And Prestige Replicas has dozens of IWC replica watches at prices so incredibly low that you can rest assured they won't last long! So, why not head over to Prestige Replicas right now and take a look at their IWC watches?

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-07.txt Pages : 25 Date : 2008-5-22 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.
