I2P dev meeting, March 28, 2006

15:08 < jrandom> 0) hi

15:08 < jrandom> 1) Net status and 0.6.1.13

15:08 < jrandom> 2) Use case survey

15:09 < jrandom> 3) ???

15:09 < jrandom> 0) hi

15:09 * jrandom waves

15:09 < Complication> Finally loaded, reading :)

15:10 < jrandom> weekly status notes posted up at dev.i2p.net/pipermail/i2p/2006-March/001274.html

15:10 <@cervantes> *** connection reset

15:10 < jrandom> heh

15:11 < jrandom> ok, while y'all dig into that, lets jump on in to 1) Net status

15:12 < jrandom> about 2/3rds of the net has upgraded to 0.6.1.13 (thanks!), and results have been mixed

15:12 < jrandom> anyone out there on low bandwidth links have any experiences they want to share? better / worse / no difference?

15:13 < jrandom> or, any results from folks on dsl-class links?

15:13 * jrandom has heard (and felt) some results on faster links (largely negative, unfortunately)

15:14 <+Complication> Well, I wanted to say that net status is a bit flaky. :) But the net said it first. :D

15:15 <+Complication> On the scale of recent disconnects, this was a very rapid recovery, though.

15:16 <+Complication> Haven't had any more massive message jams, but it still loses a lease now and then

15:17 <+Complication> Also, I think the last router run ended when a lease couldn't be renewed, so it concluded "Router hung!"

15:18 < jrandom> ah col

15:18 <+Complication> Had been ticking for 15 hours or so

15:18 < jrandom> perhaps we should adjust the watchdog to stop restarting the router under those situations

15:19 <+Complication> Retransmission is also the same as before (uncomfortably high, but apparently possible to live with - which in itself is good news)

15:19 < jrandom> the restart used to be necessary, but recurrant tunnel failure should be recoverable

15:19 < jrandom> hmm, <10%, <20%, >20%?

15:20 <+Complication> > 20%

15:20 <+Complication> I don't know many protocols which work tolerably when every third message goes missing

15:21 <+Complication> This one works :) But it used to be around 7%

15:21 < jrandom> well, thats averaged across all of the peers, so its probably quite low for most peers, but quite high for highly congested peers

15:21 < jrandom> (as shown on peers.jsp)

15:22 <+Complication> True, and I haven't taken a look at that side of the distribution yet

15:23 <+Complication> Might need to check, if for nothing else, then to verify how it's distributed

15:24 < jrandom> cool, thanks Complication

15:24 < jrandom> ok, anyone have anything else on 1) Net status?

15:25 < bar> Complication: may i ask what burst limit you are using? mine are set to 60% of my theoretical upload max, and i currently have a retransmission ratio of 11%

15:26 <+Complication> bar: it's around 80% of line speed

15:26 < bar> ok

15:26 <+Complication> On the same level as it was, when retransmission was around 7%

15:26 <+Complication> Had it higher meanwhile, but brought back down

15:28 < bar> i'll try to use 80% for a day or so to see if anything happens

15:28 <+Complication> And sustained transfer limit is around 65%

15:28 <+Complication> Actual transfer, if the total indicator is correct, averages near 60% of line speed

15:29 <+Complication> (peaks are higher)

15:30 < ashter_> for my part lot of 'no lease' thing for local destination (as i said today)

15:30 < ashter_> and a node a bit more congested

15:30 <+fox> <nextgens> hi

15:30 < jrandom> heya nextgens

15:30 < jrandom> ashter_: hmm, are you on dialup, dsl/cable, or faster? or, better said (more anonymously), are you congested?

15:31 <+fox> <nextgens> cool, jrandom is around :) you might help me :)

15:31 < jrandom> (as in, network congestion, not the numbers i2p displays)

15:31 < ashter_> dsl/cable

15:32 < jrandom> ok thanks

15:33 < jrandom> ok, if there's nothing else on 1) Net status, lets jump on over to 2) Use case survey

15:34 < jrandom> I don't expect anwers immediately, but if y'all could put some thought into the questions from the mail and post up replies (either to the forum, syndie, the list, etc), it'd be much appreciated

15:37 <@cervantes> *cough*

15:38 <+tethra> oh dear :/

15:39 < jrandom> (|grep -v -- -\!- ;)

15:39 < jrandom> ok, as I said though, bounce word through whatever fashion you care to use at your convenience. gracias

15:39 < jrandom> movin' on to 3) ???

15:39 < jrandom> anyone have anything they want to bring up for the meeting?

15:40 <@cervantes> http://forum.i2p.net/viewtopic.php?p=7442 <-- sticky thread for use case discussion

15:40 < jrandom> ah cool, thanks cerv

15:42 < ashter> (erf that happened once again, and when this occurs participating tunnels grows insanly :( )

15:43 < jrandom> hmm, to the thousands, or hundreds?

15:43 < jrandom> (there are a few fixes for bursts of new tunnels pending, should be out later this week)

15:43 < ashter> thousands

15:44 < ashter> (ok thank you)

15:44 < jrandom> ok cool. you may want to conider lowering your bandwidth limit or share percentage in the meantime

15:44 < jrandom> ok, anyone have anything else for the meeting?

15:45 < jrandom> if not...

15:45 * jrandom winds up

15:46 * jrandom *baf*s the meeting closed
