somehow this string of emails got eaten before I left
---------- Forwarded message ---------- From: Dave Taht <[email protected]> Date: Wed, Dec 23, 2015 at 6:08 AM Subject: longer rtt codel/cake testing with remote servers To: [email protected] I have long maintained a set of servers suitable for testing at a range of RTTs, but did not publish them because I'd had no desire to maintain them personally [1] for wide use, they are "in the cloud", so I do not trust their network behavior not much past 100mbit, I frequently used shapers on them merely to get interesting bandwidths at varieties of RTTS, and they cost 10 bucks a month each which I have sometimes needed for food. If people truly want to get a feel for how to modify codel without a lab handy, these boxes would be good to test against - and have long term flent data sets against, at typical home bandwidths, from your home. The most basic multi-rtt tests are the rtt_fair tests, but the rrul and tcp_upload/dlownload tests are also good for seeing the interactions on long rtts... and it's always good to do occasionally do a test to, like, tokoyo and wonder why tcp even works at all. I would like to find flent servers in finland, russia, australia/nz spain, and elsewhere in the eu. [1] These machines are active subdomains of bufferbloat.net. netperf-west: defunct (was snapon) netperf-east I do not know where this is actually netperf-eu - this is toke's server somewhere flent-atlanta # georgia flent-dallas # texas flent-freemont # california flent-london # england - this is also taht.net, at the moment flent-newark # new jersey flent-tokyo # japan [1] maintainer wanted. Also could use d-itg set up on them. Securely. I also do not remember if they all have ecn enabled by default or not. Several run the fq qdisc. I am in the progress of migrating several to kvm from xen. I would argue for consistently using sch_fq on these servers with ecn always enabled. I will check today.
