Hello, I''m still new in using tc...I wanna ask... 1. what is the difference between classless and classful qdisc?? when I made a qdisc, are I must create both of that qdisc...??? 2. what is the difference beetween three of the classless qdisc in linux redhat 2.4, sfq pfifo and tbf if I using the htb classful qdisc ??? because when I use htb classful qdisc it means I made a qdisc that

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,

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

I thought I had this all worked out, but it seems not. The following tc configuration: tc qdisc del dev ppp0 root 2> /dev/null > /dev/null tc qdisc add dev ppp0 root handle 1: tbf rate 120kbit burst 1200 limit 1 tc qdisc add dev ppp0 parent 1:1 handle 2: prio bands 3 tc qdisc add dev ppp0 parent 2:1 handle 10: sfq perturb 20 tc qdisc add dev ppp0 parent 2:2 handle 20: sfq perturb 20 tc

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 to all, I''m studying traffic shaping using kernel 2.6.8 (debian sarge). well, I have this problem: priority doesn''t work. I try with: - qdisc prio: tc qdisc add dev eth1 root handle 12: prio bands 3 tc qdisc add dev eth1 parent 12:1 handle 13: tbf rate 10Mbit buffer 1600 limit 3000

The manual says (about prio): > Because it doesn''t actually shape, the same warning as for SFQ holds: > either use it only if your physical link is really full or wrap it > inside a classful qdisc that does shape. The latter holds for almost all > cable modems and DSL devices. I want to wrap prio inside of tbf. Here''s why: I have a server on a DSL line, which has

Hi, I have a cable modem with a bandwidth capped upload rate. I''d like to prioritize packets going outbound according to the TOS header of the IP field. I''ve read through the LARTC Howto several times, and I think I have a good feel for the information it it. It also seems that what I''m trying to do is pretty straight-forward and common. Unfortunately, the HOWTO

Anyone using it? I''ve tried but after about 5 min I always get kernel panic. My setup is based on nano.txt. I works well but only if CONFIG_IP_ROUTE_MULTIPATH_CACHED=n. I just wanted to play with the new mpath feature of ip. But enabling CONFIG_IP_ROUTE_MULTIPATH_CACHED always resuts in kernel panic. I''m not using any kernel patches from http://www.ssi.bg/~ja/ - are they needed

Hi everyone, I''m new to tc but I need to use it to set up shaping on a new NAT box. In short: Each user must have their upload limited to 128kbit and downlink limited to 256kbit. Global bandwidth to be limited to 100Mbit Interactive packets to have higher priority 200+ users, so need to match packets fast So far I have managed to get the download limits working. However I need to

now, i''m learning and try to read a lot of article about tc command in linux for setting traffic shaper. but i''m doubt about In the theory about tc command ... In general, we define class under root qdisc but Is it can be possible ???? If we define another qdisc under root qdisc, Can i do it? because i have just read tc command syntax and i found this point ... syntax: tc qdisc

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

Hi i have found a problem related with tbf and the latency that the tbf calculates.. 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!!! How

I''m trying to simulate a satellite link to a Linux server to test application performance. I haven''t used any of the tc stuff before, but I blandly assured people it would be "easy" to set up a simulated long thin pipe on a spare network interface. However, now that I''m exploring, it''s proving quite difficult. Let me start with the general question

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

Hello all, My company is sharing it''s internet access with a neighbor and the neighbor in question was eating our bandwidth (both in upload and download) most of the time. I finally set up a linux router to limit the incoming/outgoing bandwidth to his network by adding a tbf on eth0 interface and eth1 interface of the router (neighbor is behind eth1 and we are in-between him and the

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

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
