Subject: [LARTC] (simplified) Rate precision
Date: Sat, 01 Nov 2003 20:32:32 +0000	[thread overview]
Message-ID: <marc-lartc-106772021820294@msgid-missing> (raw)


 Hello gentleman,

  i wrote a few days ago but did not receive any answers.

  I simplified the problem and even wrote a quick example
  which demonstrates the innacurate rate precision:

tc qdisc del dev eth0 root >/dev/null 2>&1
tc qdisc add dev eth0 root handle 1: htb
tc class add dev eth0 parent 1: classid 1:101 htb rate 2048kbit
tc qdisc add dev eth0 parent 1:101 handle 101: sfq perturb 10
tc filter add dev eth0 protocol ip parent 1: prio 5 handle 101 fw flowid 1:101
iptables -A PREROUTING -t mangle --src <ip_address> -j MARK --set-mark 101

  The example above should shape the speed to 2mbit (2048kbit) but
  unfortunately the real speed is only 1920kbit..

  Tthe only solution I have found is to add the missing rate.

  Linux 2.4.20 vanilla.

  Any comments?
