Hello, Normally, in addition to such qdisc scheduler mechanisms as FIFO, PQ, WRR, WFQ, are there any more? Then, there is a confusion on scheduler in Linux enviroment: Assume there is a qdisc, such as RED as a leaf qdisc in a router, we know, if there is packet which want to enqueue the packet, the Function red_enqueue is called, but when the packet leave the queue(when the Function red_dequeue

Hello, This is a question about diffserv on linux. We know, there is a file sch_dsmark in linux source code. Now, i want to add something in the function dsmark_enqueue, for example, i want to add a function which can add a class and queue automately in dsmark_enqueue. That is, not using the command tc. After adding one, it works well, but when add the second one, there is a kernel panic:

Hello, I want to ask what am I doing wrong. A few seconds after running this script my gateway freezes. I use the 2.4.1 kernel compiled on RH 7.0 system using the kgcc (egcs-1.1.2) compiler. I have two ethernet cards. The Internet interface eth1 is connected to the ISP, who shapes out traffic to 128Kbit. I would like to give the high priority to the e-mail and ssh traffic and to shape others

For some time now im trying to get to know what causes such configuration of QOS (kernel 2.4.25-2.4.28 + IMQ patch and ofcourse wrr): -- WRR_MAX_CLASSES=200 DEV_IN=imq0 ifconfig $DEV_IN down ifconfig $DEV_IN up tc qdisc add dev ${DEV_IN} handle 1:0 root htb default 10 tc class add dev ${DEV_IN} parent 1:0 classid 1:10 htb rate 1000kbit burst 1kbit prio 1 tc qdisc add dev ${DEV_IN} parent 1:10

Hi All, I''ve just installed WRR and am looking at tools to monitor, graph and display the system and throughput of each queue/class/filter. I''ve looked at: iptraf - only shows tcp/udp flows, not QOS queue throughputs show.pl - doesnt work with WRR (as far as I can tell) tc-graph.pl - doesnt work with WRR (as far as I can tell) polltc_ - doesnt work with WRR (as far as I can

I would like to implement an architecture to support LLQ and WFQ with Qos linux elements ! Is possible use CBQ (you can set same parameters to control WRR process) or HTB (how can i controll DRR process) structure ? My idea is to classify packets by List flows, tos flows or connections flows (as CBWFQ on CISCO ) I saw also for WRR patch (http://www.zz9.dk/wrr), but I don''t understand

I have set up wrr successfully on my bridge/shaper machine. That much works fine. I originally used sfq in the inner classes. However, there was a problem with high-bandwidth connections (web downloads, bittorrent) starving low-bandwidth low-latency connections like ssh. I would like to use prio or similar to prioritize the interactive traffic, but it does not seem to work. I have tested with

Hello, i´ve installed a Suse 8.1 minimal System with iproute 2.4.7 and iptables, Suse default Kernel 2.4.19. When I start the Wondershaper 1.1a Script I get the following Error: CBQ: "allot" is required to set WRR parameters. /home/skripte/./wshaper: line 72: allot: command not found CBQ: "allot" is required to set WRR parameters. /home/skripte/./wshaper: line 78: allot:

Hello, I am new to R. I often collect data at multiple sites and need to create separate graphs (such as scatterplots or histograms) of specific variables for each site. I have tried to do this by splitting the data frame and then using lapply, but it seems that the graphing commands cannot be called as functions. Here is a sample of my data, called "seeddist2": site

I have a machine running 2.4.25 w/ wrr, ebtables-brnf, iptables CLASSIFY and esfq patches (not using esfq, though). I have wrr set up, and within each class I want to prioritize ssh, web, etc..., but right now I am testing with pings. I have the following in my POSTROUTING mangle table: CLASSIFY icmp -- anywhere anywhere CLASSIFY set 0:6 I find that if I attach a prio

Guys Given the replies and interests lately on the WRR scheduler, and the shameless promotion of Route Hat (only kidding), my question is simple. Is there an alternative for the 2.6.x kernels? >From what I gather WRR is only available for the 2.4 kernels... Regards -- Kenneth Kalmer kenneth.kalmer@gmail.com http://opensourcery.blogspot.com

Hi If I have a HTB class with 128kbit, and I want to put "N" users in that class ( in order to share bandwidth fairly ) , which is better for me ? esfq (hash dst) or wrr ? I would attach esfq or wrr to HTB parent class. Also I''ve readed on Jim script that over WRR put a RED qdisc, but I don''t understand it. bests andres

Hi all, Here''s the situation. I have 80 users sharing a internet link of 5Mb link. The users are grouped in /29 ip addr classes so I have 10 classes of users I want to create a root htb, then 10 htb childs each with 0.5Mb bandwidth. The traffic will be directed to each class using tc filters. Now, I want that each of 8 users from each class to share equally the class bandwidth. Can I

hi list, i''m about to setup traffic shaping on a server and got some small questions about the setup. i read alot of docs/howto''s but there are still some questions i''d like to ask. setup on the box is: - external if is ppp0 (dsl) - internal if in eth0 (with ~15 nat''ed boxes) - openvpn at tun1 since all ppl on the lan feel like they have to use p2p i decided

Guys I''m looking for some advice on the following situation: We''re serving a residential complex with internet, the network has grown and with it has the problems, below is a descriptive layout of our current setup: Connection: ADSL Down/Up speed: 512kbps/256kbps (1024kbps/256kbps in the near future) 2.0GHz Celeron D with 512MB RAM Current users: 140 Maximum amount of users:

Hello I have problem with wrr and more than 1300 classes when i try to add qdisc like: tc qdisc add dev imq1 parent 1:21 handle 1000: wrr dest ip 1512 0 then i have a message like: RTNETLINK answers: Cannot allocate memory And some other problem: When I do more than 2048 filters I have message like: Classes: tc class add dev imq1 parent 1:1 classid 1:9 htb rate 1024kbit ceil 2048kbit .. tc

Guys Reading through my lartc mail, and thinking on how to tackle my next shaping solution, gave me an idea. I''d like to propose this idea for scrutiny and if it sounds viable I''ll definitely need to start developing in due time. For me in my day to day work with developing network application specifically geared for middle-tier ISP''s, and reading on other peoples

I would like to gain some idea of the XCP impact of these two CPU versions: Intel Core i7-2600, 3.4 GHz Core i7-2600K, 3.5 GHz Both have VT-x Differences 2600K does not include: Embedded Opions Available vPro Technology Virtualization Technology for Directed I/O Trusted Execution Technology Is the difference critical? Thanks, ray

I'm evaluating CentOS 5.4 for our company and one of our requirements is that it must also run on laptops. I've managed to get everything working so far except for wireless networks. The problem here seems to be that CentOS fails to provide a knetworkmanager package, and we're using KDE3 for various reasons. Thus, we're limited to Networkmanager-gnome which works but fails to

Guys All the recent discussions recently, and the knowledge of a 2.6 port, of WRR has made me very keen on trying it. I had a look at the docs and examples know but my mind is not in a very receptive state. Take this simple example. Incoming internet connection of 1mbps. Shared between up to 25 users simultaneously. I know that WRR can fairly distribute the traffic amongst the currently
