I'm not big on underscor= es, they are hard to see. (I'm getting old) I note that codel is intended to run in most cases without any parameters. limit: used elsewhere in linux for a packet limit. A packet limit is there = for practical reasons, shrinking the queue has overhead. However, codel will run just fine with infinite queue (yea!), and I suspect the default 1000 is too small on 10GigE. If there was a way to autotune it based on the underlying device, that would be good. target: At the moment this is a knob because 5ms is an eternity at 10GigE interval: Same reason I'm not big on changing these from the paper, nor on _s, nor on length. However, I'm open to further discussion. maxpacket: really confusing usages, so I went with minbytes which is explic= it Any objections? (min was overloaded with red's usage, so I felt that would be confusing, to= o) ecn: ecn was not in the paper (and it's working well) and I'd like to live in a world where ecn was the default. I think. Others disagree. so perhaps ecn and noecn? And ecn be the default (after some serious testin= g?) Parameterless is a good goal. > > > > _______________________________________________ > Codel mailing list > Codel@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/codel --=20 Dave T=E4ht SKYPE: davetaht US Tel: 1-239-829-5608 http://www.bufferbloat.net
