[19:30:35] <George Michaelson_web_689> I think benchmarking/measurement of CGN as a comparator against v4/v6 mechanisms would be very informative

[19:41:31] <Erik Kline_web_747> informative, perhaps, but I don't performance is the main criterion for selecting a transition technology
[19:42:10] <Erik Kline_web_747> as long as it "works", ease of deployment and compatibility with existing CPE/network gear is probably a bigger concern

[19:48:05] <Rob Hamilton_web_820> My network guys complain about my system using 9000 as my MTU. They want me to reduce back to 1500 (1492)
[19:48:25] <Dan Voyer_web_288> @Rob why is that ?
[19:49:19] <Jared Mauch_web_743> Fragmentation could be an issue, there are other WG's working on this stuff too, eg: draft-ietf-dnsop-avoid-fragmentation
[19:49:25] <Rob Hamilton_web_820> I have no idea why a 10Gb network should have such a small MTU. Maybe because we have some older gear that can't handle anything bigger than 1492
[19:49:32] <Dan Voyer_web_288> as an MPLS operator, we started boosting our MTU to 4000, almost 20ish years ago
[19:49:47] <Dan Voyer_web_288> we now running at 9000 MTU
[19:50:00] <Rob Hamilton_web_820> +1, Dan
[19:50:16] <Jared Mauch_web_743> (we run over 9k mtu, so we can provide 9k mtu clean L2VPN services..)
[19:51:00] <Daniam Henriques_web_413> Same here, we have clients that require 9k services, L2/IPVPN
[19:51:32] <Jen Linkova_web_819> sorry ;( wasn't looking at the time.
[19:52:15] <Dan Voyer_web_288> @Jen, you made us spit out our MTU's so worth the time :)
[19:52:23] <Jared Mauch_web_743> i found a link before to the various cellular networks MTU sizes which i think are hard coded in things like Android for the handset
[19:52:39] <Jared Mauch_web_743> some are quite odd
[19:53:01] <Bob Hinden_web_441> Why not just use ULA addresses?
[19:53:25] <Bill Fenner_web_255> And people just throw out round numbers, "configure mtu to 1400 to handle blah", and then "configure mtu to 1300 because someone else configured it to 1400 and you need to encapsulate over it"
[19:53:28] <Jen Linkova_web_819> Jared: actually I should have been more clear [disclaimer: it's 6am here ;) - fragmentation *is* an issue indeed. I'm just curious how big is "I run an overlay on top of my own network" - I'd expect it mostly be "I run overlay over Internet links" and "interconnects between two adminstrative domains"
[19:54:34] <Jen Linkova_web_819> @Dan: you know the chat is being recorded and will be available as a part of the meeting materials? ;)) Don't put any secrets here ;)
[19:55:01] <Jared Mauch_web_743> (no worries Jen, sorry it's 6a) - and Yes @Bill is right people just do "1400" then "1300" etc..
