similar to: Creating new qdisc?

Okay, here is a very simple QOS scheduler that delays packets for 2.6. It is good for testing, and might be useful for people who want to put some class of traffic into a "penalty box". Alexey''s tc command is really easy to extend to new disciplines. There is a version which knows about this scheduler at: http://developer.osdl.org/shemminger/tcp/iproute2-delay.tar.bz2 The

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''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

Hello Lartc''s users, This is my first contact. I''m trying to implement a new queue discipline based on bfifo schedule. I search on internet but there are some problem(s) that I don''t Know how to solve them and that''s why I''m here asking for your help. Well, These were my steps for the implementation: - Put the new qdisc routine

Hi, Having issues getting a replace command working correctly. The error reported is "RTNETLINK answers: Invalid argument" which isn''t descriptive or helpful. The command i''m running is: tc qdisc replace dev ppp0 parent 8001:D handle D: tbf rate 5Kbit burst 5kb latency 70ms The idea being to replace an sfq with handle D and hopefully limit a certain user in my

This patch updates the network emulation packet scheduler. * name changed from delay to netem since it does more than just delay * Catalin''s merged code to do packet reordering * uses a socket queue''s directly rather than layering on qdisc(fifo) because this is used in performance tests. * adds placeholder in API for future enhancements (rate and duplicate).

This enhances the network simulation scheduler to do simple random loss. The loss parameter is a simple 32 bit value such that 0 means no loss, and 0xffffffff is always drop. I have a new version of the tc command which takes care of conversion from percent to this value. Same patch for 2.4 and 2.6 Signed-off-by: Stephen Hemminger <shemminger@osdl.org> diff -Nru

Hell I''m new to Qdisc programming and I was wondering, what is the difference between using an internal Qdisc (like e.g. TBF does) vs. not using internal Qdisc (like e.g. SFQ does)? Can someone give me a quick rundown of pro and cons? with regards R.harper _________________________________________________________________ Undgå pop-ups med MSN Toolbar - http://toolbar.msn.dk hent den

There is an design problem with the qdisc interface that causes qlen related bugs in netem, tbf, and other qdisc''s that peek at the top of the queue. The problem is that requeue needs to be called from the dequeue function but requeue can fail. If requeue fails, then the calling qdisc can not properly handle the error. If it returns NULL, then the parent''s expectation about qlen

The HTB qdisc has a compile time option, HTB_HYSTERESIS, that trades accuracy of traffic classification for CPU time. These patches change hysteresis to be a runtime option under the control of "tc". The effects of HYSTERESIS on HTB''s accuracy are significant (see chapter 7, section 7.3.1, pp 69-70 in Jesper Brouer''s thesis: http://www.adsl-optimizer.dk/thesis/ ),

in the tc directory tc_util.h and tc_core.h use pkt_sched.h which is stored in iproute''s include directory. is there any dependency between this pkt_sched.h file and the ones that come with the standard linux kernel source. thanks. __________________________________ Do you Yahoo!?

Hi! Some time ago I faced a problem in limiting traffic on host with multiple uplinks. Since all the stuff worked nice seemed that there will be no problems. But then I realized that P2P users are smart enough to bypass limits as sfq doesn''t give fair sharing in this case (thousands of connections from one user versus few from the other). I tried IMQ but it''s instability in my

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

If i do an asterisk -rx "moh reload" MoH stops and restarts on exsisting channels. If I do an moh reload through the Manager Interface Sound is dead on exsisting channels. Any other idea for an workaround? Hi, I have problems with 1.2.14 and musiconhold.conf and realtime. I have to do moh reload at CLI to use the classes stored in mysql. Otherwise nothing is found if using

Hi, I use the patch (http://ace-host.stuart.id.au/russell/files/tc/tc-atm/) for accurate the packet scheduling on ATM/ADSL link and i think I''ve found a bug. I tried to write to the author but he didn''t answer me. I work on a Linux 2.6.17 with the iproute2-2.6.18-061002 package. I change the type of the cell_align char to short of the struct tc_ratespec in the file pkt_sched.h

Hi everybody, I''ve got a little problem when adding HTB support to my SUSE 8.1 by patching its kernel 2.4.19. After i patch kernel getting some errors, the HTB kernel option shows up but when i make modules it finds something wrong with the sch_htb.o module. Could somebody give me a hand on this? Thanks in advance. I get this information when patching (patch -p1 <
