tc troubles with pfifo_fast qdisc on 2.4.23 kernel
Hi! I was updated kernel from 2.4.22 to 2.4.23 and now tc tools can''t correctly determine default (pfifo_fast) qdisc on interface: # tc/tc qdisc ls dev ppp0 qdisc pfifo_fast 0: [Unknown qdisc, optlen=20] but, if I assign f.e. cbq qdisc for some device all show correctly: # tc/tc qdisc ls dev ppp1 qdisc tbf 8009: rate 32Kbit burst 10Kb lat 1.5s qdisc cbq 66: rate 10Mbit

PRIO and TBF is much better than HTB??
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 canĀ“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

HTB - prio and rate
Hi all, I''ve not been able to find an explanation of the relationship between prio and rate as they apply to the HTB technique. Hopefully someone on here will be able to help me. As I understand things, when prio values are assigned to an HTB setup, classes with a given prio value will only be serviced when there are no packets waiting in classes with a lower prio value. Now, does

Prioritizing VOIP traffic without sacrificing throughput
Hi, I would like to prioritize VOIP traffic when we use the phone, but other times not do traffic shaping at all. Right now I have my openwrt router set up with htb to do shaping. In order to get it to work well I had to set my upload and download speeds much lower than my line speed. With these settings, I get good VOIP reception even while surfing the net and doing a long download. However,

Need help regarding TBF Token rate setting
Hi, I would like to know how to specify the token rate when a tbf qdic is created using tc tool.. Will it be a default value when tbf qdisc is created? This could be a silly question.... im quite new to all these stuff.. but im really interested.. any help will be most appreciated... thanks in advance, sanjeev -- ______________________________________________ Check out the latest SMS

Tocken Bucket with priority?

Prioritize SSH and telnet
Hi routing-experts ! If I want to prioritize up ssh and telnet traffic with Linux 2.4 netfilter and iproute2. I''ve set outbound tcp 22, 23 and 21 TOSbits to minimize delay, but this doesn''t seem to be enough to prioritize ssh over for example http-traffic. I''m using modem to connect to Internet and got an entire LAN behind the Linux router/firewall. Well, I think most

simple TOS based setup vs more complex ones
Hi, After reading section 9 of LARTC it seemed to me that a pure TOS based QoS setup with be sufficient for a small newtork. Interactive packets could have the highest priority, second highest for DNS and small HTTP packets and lowest prio for all others. The advantage is that, the setup would be simply a couple of iptables lines, because the default pfifo_fast qdisc already implements

QoS on a bridge+NAT
I have a setup where I have three NIC in a Debian box. I have eth1 conected to internet and eth0 NAT''ed to 192.168.1.1. eth1 and eth2 are bridged together, given ip 192.168.122.2. What I want to achieve is to perform traffic shaping on the bridge as well as prioritizing the traffic from eth0 very low. (This is from trental flat ...) However it seems that I am unable to perform thhe

Changing TBF rate on the fly results in drops?
Hi everybody, it is my first message here. I tried to browse throughout older posts but I found no immediate answer. I need to change rate of a tbf queue while ip packets are already enqueued by it. If I go: tc qdisc replace|change|link dev eth0 root tbf rate 180kbit burst 1540 limit 15400 as results all enqueued packets seems to disappear. I can see that from a: tc -s qdisc ls dev eth0

tbf : rate and effective speed (newbie)
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

simple tbf rate clamping issues
Hello, I was attempting to throttle egress traffic to a specific rate using a tbf. As a starting point I used an example from the LARTC howto, which goes: tc qdisc add dev eth1 root tbf rate 220kbit latency 50ms burst 1540 I then attempt a large fetch from another machine via wget (~40 megs) and the rate was clamped down to about 12Kbytes/s. As this seemed too much, I gradually increased

Sanity Check
Hi all. I need a sanity check. I''m trying to setup my network to handle VoIP. I''m thinking that all I need to do is prioritize the realtime traffic above the interactive and bulk traffic. I see so much discussion about traffic shapping, but I don''t THINK this is needed, right? I understand the problem with bandwidth starvation, but for my application, the voip

Using TBF to throttle a PC to 5kbps
Hi Everyone, This is a simple question but I don''t understand why the below tbf is not working as expected by throttling traffic to 5kbps If I throttle a PC''s traffic using the below when traffic exceeds 5kbps packets start getting dropped (as they should) but all traffic gets dropped. not just the bit over 5kbps.

rate vs peakrate - TBF.
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

ORC JIT Weekly #12
Hi All, There was only one interesting ORC-specific commit this week: A new example showing how to initialize and de-initialize JITDylibs has been added in llvm/examples/OrcV2Examples/LLJITWithInitializers. The Extensible RTTI system (https://reviews.llvm.org/D39111) that I posted a while back has landed. While this is not ORC specific, I expect it to be used in upcoming patches to allow ORC

tbf latency problems!

I have used the following parameters for burst and limit burst 100Kbit limit 500Kbit lat81.8ms burst 6Kbit limit 6Kbit lat 0us burst 200Kbit limit 100Kbit lat 4294.9s As u can see in the 3rd column the latency for 100Kbit burst and 500Kbit limit is 81.8ms but for 200Kbit and limit 100Kbit is 4294.9s!!!

Info about IFB
Hi, I''m looking for info about IFB devices and how I can use it to incomming traffic shapping. Has IFB any web about it? Do any body known where I can find more info about it? I found this: http://linux-net.osdl.org/index.php/IFB But I can''t stand fine how to use it to allow many ifb''s devices or how to use it with "tc actions". Any help? Thanks --

simple or not? htb+prio
Hi I have now my outgoing traffic shaped whith root qdisc htb (where i configure basic rate) and tc prio (as a leaf with 4 classes) where i can set priority of different kinds of traffic. It works but htb is work-conserving so packets are only delayed (when the rate is exceeded), while i want them dropped. In the case when rate is exceeded i want to drop packets with priority set to 4, then if

TBF maximum bucket size
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
