similar to: yet another real time ip and qdisc bandwidth monitor

Hello The real-time monitoring tool that can monitor all connexions of all interfaces and the qdisc has been cleaned of a few bugs. Try the new version at http://clowncode.net Regards to all of you. Clowncoder.

Hi, Is it possible to attach another qdisq under a HFSC classfull ? I try it and the configuraton works : $TC qdisc add dev $dev root handle 1: hfsc default 30 $TC class add dev $dev parent 1: classid 1:1 hfsc sc rate ${RATE}mbit ul rate ${RATE}mbit $TC class add dev $dev parent 1:1 classid 1:10 hfsc rt umax 1500b dmax 30ms rate 200kbit $TC class add dev $dev

For a root-qdisc, can the bandwidth be smaller than the bandwidth of the device？ _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Hi there, I have two questions: 1) In the following setup: tc qdisc add dev eth1 root handle 1: htb tc class add dev eth1 parent 1: classid 1:1 htb rate 100Mbit tc class add dev eth1 parent 1:1 classid 1:10 htb rate 128Kbit tc class add dev eth1 parent 1:10 classid 1:11 htb rate 32Kbit ceil 128Kbit tc class add dev eth1 parent 1:10 classid 1:12 htb rate 32Kbit ceil 128Kbit I have observed

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

Hello, I am interrested in the monitoring of the qos qdiscs parameters such as size of the queue, enqueues, dequeues, delay in queue, I made a tool to have those results availlable at http://rawsoft.org, but it will probably not work anymore because of the kernel evolutions (the file sch_red.c is patched for the tool to work). I would like to have all the necessary data coming from the kernel

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... Im trying to setup HTB to allow me to shape traffic from two upstreams that meets on single lan0 interface. I prefer to use HTB qdisc within HTB root qdisc for cleaner rules design. Seems that it doesnt work at all. tc -s class show doesnt show any traffic on other classes attached to HTB qdisc. Linux 2.6.20.7 iproute-2.6.20-070313 Weird thing is that tc -s class show that 1: and 2:

Hello, The qdisc spy has evolved, the new version can spy on udp and tcp connections, the results are displayed upon command. There is no gui for this tool yet, but I will try to make one. If you want to try: http://rawsoft.org Vincent Perrier

Hi, I''ve read the documentation about HTB and I pretty much managed to grasp how it works. In theory. But there still are some questions and I want to check with you to see if I understand things correctly. So here goes: 1) when used on a router for shaping traffic done by clients connected to it, shaping is done on the interface connected to the cable/dsl modem. If I wanted to create

After some digging in openvswitch code. My wild guess is that vlan tag reconfiguring triggered iface_configure_qos (vswitchd/bridge.c), which in turn called netdev_set_policing to reset ingress policing rate. Although there's no ingress_policing_rate set in my case, existing ingress qdisc still remove by default. Could some openvswitch guy help to confirm and suggest how to fix or workaround?

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

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

now i''m read a lot of knowledge paper about traffic control in linux because now i''m try to develop and research about traffic shaper so can everybody tell me about my topic ... Is it can do for real???? my topic is " now, many organization use traffic shaper for control traffic and bandwidth because don''t want something example some mac address, ip address,

Hello, i noticed that the ingress qdisc is not working properly anymore in 3.0.4-1 (back in 3.0.2 the ingress qdisc was working for me): Install the ingress qdisc to peth0: # tc add qdisc dev peth0 ingress ... generate some traffic ... # tc -s qdisc show dev peth0 qdisc pfifo_fast 0: bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 Sent 324884 bytes 1749 pkt (dropped 0, overlimits 0 requeues

Hi, all I am interested in Linux related QoS, especially PRIO queue discipline (qdisc). I test some experiments about PRIO qdisc. Host A ------ Router A --- Router B --- Host C | 1Gbps | Host B ---------+ +-------- Host D flow 1 : Host A -> Host C (TCP) flow 2 : Host B -> Host D (UDP) priority 1 queue (pfifo, size 1000 packets ) : flow 1 priority 2

Hi all, I am trying to implement a new qdisc, but I''m having trouble. Here''s what I''ve done: I''ve copied the TBF source into a new file, and modified it to represent my new qdisc. Then added it to the default qdiscs in the Makefile. I modified the header files include/net/pkt_sched.h and include/linux/pkt_sched.h to reflect my new qdisc. The kernel

With outbound QoS setting in Libvirt XML, libvirt will add a tc ingress qdisc for traffic shaping. Then if you set VLAN tag to that tap device, this qdisc will automatically gone by no reason. Could anyone shed some lights where should I look into? I'm really confused and got no clue here. Thanks! Steps to reproduce -- # virsh start instance-name # virsh dumpxml instance-name ...
