Requirements:
There is an arbitrary number of users per group. Bandwidth for any particular group is 1000kbps. Bandwidth for each user in a group is 70 kbps. At any time no user should not consume bandwidth more than 70kbps. I am using tc & iptables & ipset.
ipset -L slowips
Name: slowips
Type: hash:ip
Revision: 1
Header: family inet hashsize 1024 maxelem 65536
Size in memory: 240
References: 3
Members:
172.16.79.3
172.16.79.4
IPTABLES:
iptables -t mangle -I POSTROUTING -m set --match-set slowips dst -j CLASSIFY --set-class 1:12
My script for TC :
#!/bin/bash
tc qdisc del dev eth0 root
tc qdisc del dev eth1 root
tc qdisc add dev eth0 parent root handle 1: hfsc default 11
tc class add dev eth0 parent 1: classid 1:1 hfsc sc rate 1000kbps ul rate 1000kbps
tc class add dev eth0 parent 1:1 classid 1:11 hfsc sc rate 1000kbps ul rate 1000kbps
tc class add dev eth0 parent 1:1 classid 1:12 hfsc sc rate 70kbps ul rate 70kbps
tc qdisc add dev eth0 parent 1:11 handle 11:1 pfifo
tc qdisc add dev eth0 parent 1:12 handle 12:1 pfifo
With the above setup, single user gets 70kbps bandwidth, when another user logs in, the 70 kbps bandwidth is divided between them. What I actually want is for newly logged in user to get 70kbps bandwidth, as slab is 1000kbps.
