Subject: [Cake] overheads or rate calculation changed?
Date: Mon, 18 Dec 2017 20:32:49 +0000 [thread overview]
Message-ID: <31d49a5d-02a2-3dc8-a455-52d453b83bdf@gmail.com> (raw)
Been running a cake cobolt from april for some time using
tc qdisc add dev ppp0 handle 1:0 root cake bandwidth 19690kbit raw
overhead 34 diffserv4 dual-srchost nat rtt 200ms
tc -s qdisc ls dev ppp0 (ppp0 is pppoe)
qdisc cake 1: root refcnt 2 bandwidth 19690Kbit diffserv4 dual-srchost
nat rtt 200.0ms noatm overhead 56 via-ethernet
Which is backed off a couple of kbit and tests well (overhead 33 + udp
flood is over limit)
With current cobalt + current tc the same command is under rate - I
don't know if its rate calculation or overheads calc changed.
overhead 20 (-14) is still under but overhead 12 (-22) is over.
I was hoping one of those would be correct, but no.
Any ideas/known changes?
