similar to: Patch to allow for the ATM "cell tax"

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 I''m using wondershaper like script. But noticed imperfect scheduling. By googling, I found some patches that takes the aal5 atm overhead in the scheduling algorithms. http://www.adsl-optimizer.dk/ADSL-optimizer/ Before trying it, has anyone tried these patches? they apply on 2.4.29 kernel and 2.6.9 TC. I use centos4 with a 2.6 kernel, so I can''t try these easily. Thanks

OK, here it is. Near perfect bandwidth calculation for ADSL users. Patch iproute2 with the HTB stuff and then this: It''s still a hack (as far as I can tell) because we are patching the rates tables, and hence I think it is only loosly coupled with the actual calculation of bytes in each bucket. However, it works very nicely for me! I have only been lightly testing with

Hi. I wrote in a reply to a mail on here recently that you can''t set mpu (minimum packet unit) on HTB as you can on CBQ. I''ve just noticed that there is a patch on devik''s site which does mpu and overhead. http://luxik.cdi.cz/~devik/qos/htb/ For dsl users mpu is, for practical purposes going to be 106 - overhead is still variable though, depending on packet size.

Anyone know if it''s possible to interleave two IP packets when using PPPoA and VC based lines? Can it be done with any PPPoE implementations? The goal is to reduce the delay when you have a high priority packet waiting, but a lower priority (large) packet already started going out ahead of this packet. I don''t want the overhead of much smaller MTU, which is the other way

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/ ),

Hello, i have a htb setup where the root and (nearly) all child classes has a ceil rate with max up from my adsl line. But the root class don''t reach the ceil value but some childs are get a huge backlog.

Guys Considering the festive season is upon us, thanks to everyone contributing to the list and helping all the readers with your great input! I don''t want to mention names, I''ll most certainly leave someone out. With this mail I''d like to test some theory on bandwidth management, with my own successes and failures during the past year. Sharing a link between 200

I know there is that handy patch available to very efficiently use ATM bandwidth, but I was wondering what the best values to use with a non-patched iproute2 would be. Anyone here care to check my logic in coming up with these numbers and perhaps suggest better values? My transmit speed is 768kbps per ADSL line (I have two). This is the HTB shaping I do on the interface (logic used for this

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

Under Linux, i can configure my DSL connection with pppoeconf (debian), without configure my Ethernet interface (eth0), just load kernel module fo ethernet interface, launch pppoeconf here is it. Another way is to configure the DSL interface (eth0 -> ALCATEL Speed Touch Home) with IP:10.0.0.1 so i can telnet or access with an web explorer the modem on 10.0.0.138. After i launch pppoeconf and

It seems Andreas Klauer''s fairnat has experimental support for using HTB''s MPU and overhead options. fairnat.config: # Use MPU for HTB. From the LARTC Howto on MPU: # "A zero-sized packet does not use zero bandwidth. For ethernet, no packet # uses less than 64 bytes. The Minimum Packet Unit determines the minimal # token usage for a packet." HTB_MPU=0 # HTB_MPU=64

Hello *! My trafficshaping (tc-htb) drops packets very early, at least i suspect this. It drops about 30% fo the packets. The traffic-generating appication is running locally on the shaping host. I think i can lower this rate by increasing the packet-buffer, because the locally application will slow down with increasing buffer (tcp/ip). But i can´t find any options for that, i cycled the manual

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

I''m trying to do some very simple rate-shaping on an interface. I want to limit my 100baseT interface to 7 megs both ingress and egress of the interface. I''ve been hacking my way through the documentation and some examples and I''ve come up with the following configuration for tcng that seems to do what I want. I''m curious if some of the other experts out

Hi all ! I''m building a network appliance whose goals are to enhance Voip quality on 512/128k DSL links. But, i have a voice quality problem, and i think i''m doing something wrong, but i can''t find what. Please excuse my terrible english, i''m french. >From what i''ve read, tc is the tool i need. I read the documentations, readmes and lartc.org

J, What i meant is...like in Linux you make use of the two external connections and collate them as mentioned in the document. Can you try keeping the Linux box in front of the two windowze boxen and collate the two LAN connections coming from them as mentioned in the HOWTO???.

Hello, I am wondering if any of you knows how to add BR2684-rt nas interfaces into a Ethernet bridge, I know that brctl will work with BR2684-br, but not for BR2684-rt. Many thanks!
