[00:30:19] <psa> Questions?
[00:30:32] <psa> Kevin Fall at the mic
[00:30:34] <Will Ivancic> I  can ask.  I have to look them up.
[00:30:50] <psa> (concern about clock moving backward)
[00:31:34] <psa> Kevin Fall: could exchange variance and confidence interval, too
[00:32:06] <Some Guy> Question for the mic: Does this algorithm rely on directly neighboring nodes?
[00:32:12] <Will Ivancic> Does this method use bundle protocol to sync or some other communications?  
If bundles, what is the lifetime of the bundle set to?  
If I understand correctly, the proposed method achieves "relative time" synchronization.  How does that map to Absolute Time (UTC synchronization)?

[00:32:16] <Will Ivancic> 4 questions
[00:32:28] <psa> I can channel to the room, prepend with <mic>
[00:32:35] <Some Guy> ok
[00:32:39] <Will Ivancic> OK thanks
[00:32:48] <Some Guy> <mic> Does this algorithm rely on directly neighboring nodes?
[00:32:51] <Will Ivancic> I understand there is a delay with the mp3 
[00:32:57] <psa> Jörg at the mic

[00:34:26] <psa> Jörg expressed concern about timezone differences
[00:34:40] <Will Ivancic> My phone slept and had the wrong time by 1 hour until I resynchronized
[00:34:48] <Kevin Fall> (my watch has another time on it too-- 1636)
[00:35:03] <psa> Stephen: what if the time data is not exchanged immediately (e.g., on USB stick)

[00:36:40] <Will Ivancic> space systems often have a time tick, with things corolated on the ground.
[00:37:15] <psa> questions channeled
[00:37:29] <Some Guy> psa: Thanks
[00:37:34] <Will Ivancic> I hear.  Time delay is not bad at all.
[00:37:53] <psa> Kevin Fall at the mic
[00:37:58] <Will Ivancic> At least, I cannot precieve it from my relative position in time and space.
[00:39:26] <Some Guy> I missed the units of the steps on chart 16... that would be interesting to know... I'll ask on the list
[00:39:35] <psa> Stephen asks the presented to send a pointer to the list
[00:39:48] <psa> s/presented/presenter/
[00:39:57] <Kevin Fall> I think he said micro to millisecs, but its an abstract simulation, so I think you can choose your favorite unit...

[00:55:44] <psa> presentation ended
[00:55:46] <psa> questions?
[00:56:03] <Will Ivancic> Was there discovery of nodes or where something the equivalent of a "host table" established in each node prior to deployment?
[00:56:03] <psa> Kevin asks for the equation slide
[00:57:16] <Will Ivancic> How mcuh disconnection was in the system.  Rough order of magnitude.  
[00:57:43] <psa> please prepend questions that you want me to channel with <mic>
[00:57:58] <Will Ivancic> Something like in general, nodes were isolated for 1 minute, 10 minutes, etc....
[00:58:43] <Some Guy> <mic> how much pre-configuration was done?  Are all nodes aware of others as part of the initial config?
[00:58:46] <psa> that was Elwyn Davies and then Jörg Ott at the mic
[00:59:52] <psa> just letting jabberites know that there's a few people at the mic
[01:00:09] <psa> unidentified person at the mic
[01:00:14] <Will Ivancic> Understand, jabber has to wait our turn.

[01:02:09] <psa> Hiroshi and Elwyn trading places at the mic
[01:02:38] <psa> Brenton Walker at the mic
[01:02:57] <Some Guy> Sounds like they're asking about "potential" and how it's initially configured/calculated
[01:03:22] <psa> Hiroshi at the mic again
[01:03:27] <psa> Some Guy: yes
[01:03:31] <sftcd> right - the presenter skipped over that a bit and folks were wondering
[01:04:14] <psa> I will get to channel the jabber questions
[01:04:35] <psa> Bernie Hoeneisen at the mic: what is reasonable time?
[01:04:49] <Hajime Tazaki> <mic> Is the code publicly available ?
[01:05:19] Some Guy is now known as Joseph
[01:05:19] Joseph is now known as Some Guy
[01:06:16] <Will Ivancic> Just naming, not routing info
[01:06:28] <Some Guy> that sounds related to my question
[01:06:40] <Will Ivancic> My question had to do with URI names.
[01:06:51] <Some Guy> oh
[01:06:57] <psa> Will Ivancic: so I did not channel correctly?
[01:07:02] <Some Guy> well I'm curious if Are all nodes aware of others as part of the initial config?
[01:07:04] <psa> Will Ivancic: maybe take it ot the list
[01:07:12] <psa> Some Guy: I think he said no
[01:07:17] <Some Guy> ah ok
[01:07:19] <Will Ivancic> I think the workgroup chairs rechanneld your channel
[01:07:25] <psa> Go Kawaguchi at the mic
[01:07:31] <psa> Will Ivancic: :)
[01:07:46] <Some Guy> psa: I do appologize, my audio keeps dropping
[01:07:59] <Some Guy> psa: so I miss bits and pieces of discussion
[01:08:06] <Will Ivancic> Mine autido is rock steady.
[01:08:30] <Some Guy> Will Ivancic: clearly I need your service provider.... or DTN ;)
[01:08:34] <psa> next speaker
[01:08:38] <psa> :)
[01:08:39] <Will Ivancic> I am on the end of a Cable Modem and audio is using Windows medai player - go figure that would work.

[01:25:38] <Will Ivancic> Question for mic:  Is current NICT store and carry forward proposed implementation using bundling RFC5050 or other store and carry forward techiques or both
[01:26:33] <psa> Kevin asked about the kind of commercial interest
[01:28:12] <psa> answer seems to be yes, based on DTN 2
[01:28:13] <sftcd> answer is yes based on DTN2
[01:28:24] <Will Ivancic> Go it ;

[01:45:52] <Will Ivancic> What were the clock issues?
[01:47:04] <Will Ivancic> Did I understand correctly, this was all static routing, not discovery or opportunistic routing?
[01:48:02] <Will Ivancic> How did you know what to set the bundle lifetimes too?
[01:48:24] <Some Guy> mic please...
[01:48:39] <psa> Elwyn Davies at the mic

[01:53:20] <psa> :P
[01:53:36] <Will Ivancic> I do not see a presentation on this topic on the DTNRG materials area.

[02:04:12] <Some Guy> <mic>So not having the slides, maybe this was addressed... but how would this work if this URI scheme is used in a situation where bundles are duplicated in order to promote successful delivery?  If I use dtn:find:printer<blah> - might I end up with 20 copies of a printout?

[02:25:23] <Will Ivancic> I agree with Brenton's questions / presentation.  I just think we are to early in this area.  However, we should keep these questions in mind.
[02:26:08] <Will Ivancic> We need more siconnection and more discovery
[02:26:37] <Will Ivancic> Most I have seen are high degrees of pre-configuration.
[02:28:09] <Will Ivancic> I also do not see much URI name resolution and re-resolution.  Current implementations assume things don't change.
