similar to: HTB: far unequal behaivor at a slight conf rate change

Hello, 1. I currently have a 128kbps cable link to the internet..and I''m sharing this connection with others. I''ve made the following script(for alocating bandwidth depending on the services used: browsing, squid, games like counter-strike, icmp, ssh), which unfortunately isn''t working very well as the response times I''m getting upon pinging the server

Hi, I would like to ask about status of VDE and libvirt. I found a thread from http://www.redhat.com/archives/libvir-list/2008-February/msg00030.html. I am not interested in connecting the VDE to the outside world. I have created a FW machine using macvtap. To this machine I would like to attach machines from different zones (dmz, prod, cust). I was thinking on using VDE and vlans (FW would

Hi, Can any one explain what the following can be used for ? I want to know , so that i can use it in the future :-) > Add support for VDE through libvdeplug. > > When compiled with vde/device.c, tinc will connect to a vde_switch instance > instead of using a tun/tap device. Perry

Hello, after spending several hours reading archives, I decided to write new post. I successfully set up packet classification, made some basic HTB setup, made some simple graphical representation from HTB statistics data... BUT, I cannot figure out how to refine HTB to get this behaviour: I need that class "p2p" should be the last one to get some link capacity. If I set both RATE

An earlier exchange about someone seeing the rate larger than the ceiling is posted below. Andy explained the reason for the "above ceiling" rate in Daniel''s output . . . but I just saw an example that doesn''t fit. >> tc output >> class htb 1:14 parent 1:1 leaf 14: prio 1 quantum 3072 rate 256000bit ceil 282000bit burst 1820b/8 mpu 0b overhead 0b

Hello! I need to switch from htb2 to htb3, because of speed issues (for me, htb2 is unable to handle more then 100mbit duplex with ~550 classes), kernel profiling shows htb_dequeue_prio at 1st place with 3x isolation. So, I''ve moved from 2.4.19 to 2.4.25 kernel (hi-pac for classification/marking and htb3 for queueing), and traffic rate drop from 100 to 20mbit. What can be wrong? The

Hello list, I need to realize a complicated custom shaping setup, and given very little experience with shaping I just can''t wrap my head around it. I am not seeking a complete script, I just need an idea/a set of pointers on how to best subdivide traffic accordingly to my needs, and which shapers to place on every leaf. I am very experienced with netfilter and have minor experience with

Hi, I have a server and ten clients in a Gigabit network. The server has 125mbps network bandwidth. I want that the server has 40Mbps bandwidth reserved for client 1 (IP 192.168.5.141), and the rest bandwidth is for all other clients. My script looks like this (I use IFB for incoming traffic): #!/bin/bash export TC="/sbin/tc" $TC qdisc add dev ifb0 root handle 1: htb default 30

Eric, I''ve attached the output from the command you requested below. I''m using kernel 2.6.17.12 and tc version ss060323. I''m have a nforce4 onboard giggabit controller using the forcedeth driver, if that makes a difference. Charlie, I''ll take a look at the Apache model for throttling, thanks. I was going for tc because was going to try to add additional

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.

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

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

Im using a Linux machine with standard pc hardware with 3 seperate PCI network interfaces to operate as a DiffServ core router using Linux traffic control. The machine is a P4 2.8ghz, 512mb RAM running fedora core 3 with the 2.6.12.3 kernel. All links and network interfaces are full duplex fast ethernet. IP forwarding is enabled in the kernel. All hosts on the network have their time sychronised

Hello, I use HTB with linux-2.4.20-ac1 and iptables-1.2.7a (pathced for IMQ). I configured one HTB qdisc on an IMQ device. This qdisc has some classes (about 5) and all of the classes has qdisc pfifo. I sometimes got out from my linux (while I was working) and I found in logs: Dec 4 11:49:27 core kernel: HTB init, kernel part version 3.7 Dec 4 11:49:28 core kernel: HTB: quantum of class

Hi, I''m trying to perform some (what I consider) basic traffic shaping on our network utilising HTB.
