I was testing HTB using IPerf TCP traffic and the results were very good. Until I tried to add some UDP traffic the results were a little strange.
this is my setup
tc qdisc del dev eth1 root tc qdisc add dev eth1 handle 1:0 root htb default 2
tc class add dev eth1 parent 1:0 classid 1:1 htb rate 1mbit tc class add dev eth1 parent 1:1 classid 1:2 htb rate 500kbit ceil 1mbit tc class add dev eth1 parent 1:1 classid 1:3 htb rate 500kbit ceil 1mbit
tc filter add dev eth1 protocol ip parent 1:0 prio 2 u32 match ip protocol 17 0xff flowid 1:3
tc qdisc add dev eth1 parent 1:2 handle 20 pfifo limit 10 tc qdisc add dev eth1 parent 1:3 handle 30 pfifo limit 10
This simple setup should split the 1mbit bandwidth between TCP and UDP. I run 2 IPerf clients simultaneously Server: iperf -s -p 200 iperf -s -p 400 -u Client: iperf -c $ServerIP -p 200 iperf -c $ServerIP -p 400 -u
then UDP traffic takes about 750kbit and TCP traffic takes about 250kbit Can anyone tell me why is that?
thanx, Ibrahim
