Hi Here is our problem : ______________ eth1 | | eth0 INTERNET--------| LINUX router |---------- LAN |______________| we want to allow our LAN users to use only 128Kbit (16KB/s) of our total bandwidth. I'm using these rules to do that : tc qdisc add dev eth0 root handle 10: cbq bandwidth 10Mbit avpkt 1000 tc class add dev eth0 parent 10:0 classid 10:200 cbq bandwidth 10Mbit rate 128Kbit allot 1514 weight 12Kbit prio 5 maxburst 20 avpkt 1000 bounded tc qdisc add dev eth0 parent 10:200 sfq quantum 1514b perturb 15 tc filter add dev eth0 parent 10:0 rotocol ip prio 3 u32 match ip dst 192.168.1.0/24 flowid 10:200 but when I'm teting these rules by downloading some files to our LAN, The traffic always begins with a high traffic ~100KB/s for several seconds then the traffic dropped to the desired level 16KB/s I also notice when I'm doing several ftp's the traffic exceeded the desired level by a liitle KB/s How can resolve this ?
