[one-users] Transfer/bandwidth limits?

[Ionut Popovici]

For download you can use htb on vnet interface

tc qdisc del dev <vnet interface> root
tc qdisc add dev <vnet interface> root handle 1:0 htb default 2
tc class add dev <vnet interface> parent 1:0 classid 1:1 htb rate 
512kbit ceil 512kbit
tc filter add dev <vnet interface> parent 1:0 protocol ip u32 match ip 
dst <ip for host> flowid 1:1

tc -s qdisc show dev <vnet interface> it will queryng discipline
tc -s class show dev <vnet interface> it will show classes
tc -s filter show dev <vnet interface> it will show filter that attached 
to class and if working.

rate = flat rate guaranteed that can be exprimatedt in kbit or mbit
ceil = max rate can be borrowed from master .. but here you can user on 
rate that can have the interface

some more info

it is old but is best qos discipline for linux 10 times better that cbq
