Hi all, Would there be time at the OGF upcoming week to discuss how to deal with multilayer E2E monitoring? Basically, we have been trying to implement something like that, but got stuck, since the current XML was not going to work no matter how we bend it. Peter Tavenier (a colleague of mine) and I asked for opinions on the perfsonar-dev list, explaining our rational for doing this. See: https://lists.internet2.edu/sympa/arc/perfsonar-dev/2010-09/msg00010.html and more mails in that thread. Frankly, the discussion that followed in our group at SARA reminded me a bit on discussion we had on the NML list 3 years ago, and I'm not sure I want to repeat that. Also I prefer to have a slightly faster time progressing time. :~) So I was hoping to get some feedback how to proceed and if other share this interest. Regards, Freek

Hello all, As I might actually make it there(28th), I might as well chime in. Afaik the following topics have recently been discussed and I would expect them to be on the agenda: - Wrapping up(hopefully) result codes - How to advertise capabilities (From last call) - Overall progress Others would be: - how to deal with multilayer E2E monitoring - Streaming? there was quite some interest in this before everyone went on vacation, not sure if it's a priority atm. (I expected more momentum within nmc) - Others? With regards to multilayer E2E monitoring I'll leave that to the experts. As I recall as we asserted that the whole thing was quite non-trivial and full of pitfalls, I though the consensus was to incorporate/reuse an other spec. What do you want to nail down, sort out at OGF specifically Freek? Kind regards, Michael On Mon, Oct 25, 2010 at 3:27 AM, Freek Dijkstra <Freek.Dijkstra@sara.nl> wrote:

I don't feel too good thinking that the topic of streaming is untouched. Recently I was collecting plans for future work in GN3 project and Nina declared to work on it with you. Cheers, Roman

This is correct - I've declared I am interested in the topic, however I am not sure if there are plans how exactly to proceed. Best regards, Nina

There is no detailed plan. We've got only a topic roughly defined and initial proposal made by Michael. Let's try together prepare such plan. Roman

If you are able to make it, and if you have some work you would like to present I am sure we could devote 10-15 minutes in the second session. Since attendance may be low for our session it may make more sense to continue the discussion on the mailing list. -jason

Hi Freek/All; I think we can add this to the agenda for the second session, I will try to get the agenda out today. Its a shame that some more people directly involved in the issue are not present, but it is a timely and valuable topic for this group. There is some recent work in this area that uses the in-progress NML schemas. I think we should focus the discussion more on data formats/protocol exchanges than the actual process of circuit monitoring (although who knows, the discussion may go that way :)). -jason On 10/25/10 3:27 AM, Freek Dijkstra wrote:
