Re: [Bloat] Best practices for paced TCP on Linux?

[Dave Taht <dave.taht@gmail.com>]

The test HD tcp stream is up at

http://cesur.tg12.gathering.org:9094/

on both ipv6 and ipv4. They are streaming anywhere up to 1000 users,
and there is an astounding amount of ipv6 present - 73% of the room
has an ipv6 address.

I took some captures from california last night, they were
interesting. I think a few more captures would also be interesting.

One indicated throttling at the isp at t+60 seconds, the others showed
stuff dropping out for large periods of time. (170ms rtt here!)

I'd like to look into what percentage of the failures I observed
happened on the wifi hop vs the ethernet gateway
since then many changes where made, and I'm low on sleep. (what do
geeks do on a friday night?)

I don't know if they are still trying sfqred or qfq in production -
they worked! - but had little effect (as is to be kind of expected
with the instantaneous queue length being so short and bandwidth so
high on their first and nearest hops....)
