Hi all, I''m trying to setup htb on a box with the following class configuration: class htb 1:2 root rate 4Mbit ceil 4Mbit burst 2099b/8 mpu 0b overhead 0b cburst 2099b/8 mpu 0b overhead 0b level 7 Sent 0 bytes 0 pkts (dropped 0, overlimits 0 requeues 0) lended: 0 borrowed: 0 giants: 0 tokens: 4300 ctokens: 4300 class htb 1:4 parent 1:2 leaf 4: prio 7 quantum 1000 rate 1Kbit ceil

Hello. Sorry for my poor english =) I have following config for traffic prioritization: tc qdisc add dev eth0 root handle 1: prio tc qdisc add dev eth0 parent 1:1 handle 10: tbf rate 7000kbit buffer 1600 latency 2msec tc qdisc add dev eth0 parent 1:2 handle 20: sfq tc qdisc add dev eth0 parent 1:3 handle 30: tbf rate 3000kbit buffer 1600 latency 50msec tc qdisc add dev eth1 root

Hello, I''am successful using a linux (2.4.20) bridge and the cbq.init_v0.7 script for traffic shaping. But I can only use the queuing discipline tbf (LEAF=tbf). If I try use queuing discipline sfq or none then tc applies the rules but no shaping occurs. Is this problem a normal behavior when using bridging ? I tried to use htb.init (using patched tc binary). It accepts the rules but

Hi, I have a basic router that is shaping traffic, and it seems to be working at the moment. We have a 100Mbit connection to the internet, however we get charged for each mbit that we use and so have to shape/limit the traffic to avoid huge bills and my boss getting cross!! We have a /29 subnets set up as follows: tc qdisc add dev eth0 root tbf rate 0.8Mbit latency 50ms burst 10k tc qdisc add

Hello mailing list, i stand bevor a mystery and cannot explain it J. I want to do shaping and prioritization and I have done these following configurations and simulations. I can´t explain, that the combination of PRIO and TBF is much better than the HTB (with the prio parameter) alone or in combination with the SFQ. Here are my example configurations: 2 Traffic Classes http (80 = 0x50) and

Hi all! I just started to experiment with bandwidth management using tbf. I have the folowing problems with token understanding: 1) What unit is token? Is "1 token = 1 byte" ? If this is so, then with rate=0.5mbit and HZ=100 the bucket gets filled with 0,64kb (655 tokens) every 10ms? 2) How much tokens are used for one packet (1500)? 3) And token unrelated question. Does

Hi I''m completely stuck with the tcng language - I assume there must be some way to arrange queues hierachically like eth1 | TBF | PRIO / \ class class but my attempt (below) produces a "inferno.tc:8: qdisc "tbf" has no classes near "prio"" when run through tcc. dev eth1 { egress { tbf (rate 128kbps, burst 64kb,

Hi All, I want to setup a machine to connect to internet at a limited rate of 64 kbps. That machine is connected to a switch. so my LAN and Internet both comes from the same eth0. How can I limit only the internet access from this machine to 64kbps and still using 100mbps for LAN I am trying to implement this Please guide me If i am wrong. I mark all the packets going out to LAN. Then I can

Also, the "mtu" parameter of TBF is now optional. The complete list of changes is below. - Werner

This is my first attempt at understanding lartc: I want to throttle outgoing bandwidth fo a certain tcp port and leave other traffic the way it was. so I put a prio qdisc at the root of eth0 (dummy priomap since i want to use filters to switch bands): $ tc qdisc add dev eth0 root handle 1: prio bands 2 priomap 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 then attach a tbf qdisc at 1:2 : $ tc qdisc add dev

Probably this is an old question, but i''m not able to find nothing about... So, i''ve just started to play with tc to limit the transfer speed to my hdsl connection. I''m using the tbf and the command # tc qdisc add dev eth0 root tbf rate 10kbit latency 50ms burst 1000 Then i''ve tried to transfer a big (20 Mbyte) file onto my lan, using ftp and the client

Hi! Is there any way to do just plain vanilla TBF (Token Buck Filter) type shaping on a group of ips/networks, not an entire interface. Currently the only way I know how to shape in Linux is to use HTB or CBQ, but both of these need a total rate and then you need to subdivide that into classes. That is not what I want. All I want is Cisco generic traffic shaping style shaping (or similar to how

Hello, I am attempting to use the LARTC traffic control to simulate a radio link that has variable bandwidth and availability. The basic bandwidth could be as low as 500 bits/sec but will generally be about 4000 bits/sec. If the simulated radio link is unavailable (zero bandwidth) then packets should be queued until a link is re-established. i.e. Initial bandwidth is 5000bits/sec then to 0

Hi, Can you please explain to me the difference between rate and peakrate, in conjucture to TBF. IMHO, rate : controls the no. of pkts flowing through the pipe, and peakrate : controls the no. of tokens flowing through the bucket. A funtion(?) of peakrate and mtu is rate. If this is true, why do I need to specify both peakrate and rate? Regards, suraj. __________________________________ Do

Hi all, I''ve tried to look for this info in previous messages but had no luck. I''ve a 2.4.20 kernel on an Intel arch., all TC is configured and it seems to work. Anyway, I''ve had some troubles in configuring TBF via tc: 1. when I configure burst or minburst to be, say, 1500b, when I peek the configuration with "tc -s qdisc" the answer is that

Using below configuration multiplied by 3000+ nodes to control bandwidth causes very high kernel cpu usage (99.5%) narrowed it down to the mangle table. Any ideas to do this more efficiently would be appreciated. The mangle table entry (indicated by ***) is sucking all the cpu. I am running RH7.3 kernel 2.4.18-3 and iptables 1.2.5 This setup has worked well for more than 1000 devices but as the

I''m trying to fill a token bucket with enough tokens to burst several gigs of data. However, it doesn''t seem to get any higher than ~3.9GB: >tc qdisc add dev eth0 root tbf rate 1440kbit latency 50ms \ burst 16000000000 >tc qdisc show dev eth0 qdisc tbf 800b: rate 1440Kbit burst 3908420240b lat 2197.8s A smaller attempt of ~1.6 gigs works just fine: >tc qdisc
