similar to: HTB + GRED (santa clauss plz help me out)

Hi, I am trying to get assured forwarding/expedited forwarding with gred and htb working. Below is the script I am using. The following steps are what I thing is how the script works. My problem is that if I remove the HTB qdisc from the script and have the GREDS parent as the dsmark it works, but when I add the htb as a parent of GRED and DSmark the parent of htb it does not work? Any

Hi i have configured my server with cbq and gred. The problem is that the cbq doesnt drop packets. The cbq is configured at a rate of 500Kbit "qdisc cbq 4: rate 500000bit (bounded,isolated) prio no-transmit Sent 100103048 bytes 73933 pkts (dropped 0, overlimits 0) borrowed 0 overactions 0 avgidle 24000 undertime 0 " The traffic that being generated is more than 5Mbit with the

Hello all, Please could someone help me with this, I have been trying for days to get this to work. I would like to have BE, AF & EF classes with HTB qdisc. I can''t find any scripts online where this has been done. If I enable this filter: #tc filter add dev eth0 parent 2:0 protocol ip prio 1 \ #tcindex mask 0xf0 shift 4 pass_on then BE & AF classification seems to be fine but

Hi, I am tring to setup AF on my router using GRED/HTB. I plan to mark and set the DSCP with iptables and the ingress qdisc to set the tc_index for the proper GRED vq(1-12). My question is: Is there a way to allow for priority between the af classes and within the af classes? also would it be possible to to the following: HTB(6Mb) | GRED(1)grio HTB1 (af1) (1MB) GRED(1-3)grio |

All: I am tasked with creating an environment in which DiffServ and IP precedence is handled as close to RFC specification as possible. I have a few problems with implementing this based on current queueing structure. Here are a few of my questions. 1.) Is there any way to get DiffServ AF drop levels without using DSMARK and GRED? Ex. AF11 Gred DP 1 AF12 Gred DP 2 AF13 Gred DP 3 2.)

Hello, We know, VQs are used in Gred to offer different schedulers, in order to make clear what the VQs are, I have read the sch_gred.c in net/sched/. In the function gred_enqueue(), at first it will find the VQ(q) according to the lower four bits of the skb->tc_index, then some parameters of the q is modified, such as q->packetsin and q->bytesin. At last the packet was put into the

Hi, just wondering if this type of configuration would be possible for using AF and EF classes. HTB (6.0M) --GRED 5 (AF1) --HTB(1M) [is it possible to have this with a 1M rate and a 6M ceiling?] --GRED [3 greds using grio] VQ1 -3 --GRED 4 (AF2) --HTB(1M) --GRED VQ1 -3 --GRED 3 (AF3) --HTB(1M)

hi all i am a new commer of linux community. i want to how does skb->tcindex value change exactly. it confused me indeed. i have a script reads: (1) tc qdisc add dev eth0 root handle 1:0 dsmark indices 64 default_index 0x161 set_tc_index (2) tc filter add dev eth0 parent 1:0 protocol all prio 1 tcindex mask 0xfc shift 2 pass_on (3) tc filter add dev eth0 parent 1:0 prio 1 handle 0x0a

I''m successfully using HTB + GRED to shape traffic based on the DSCP field. I would like to strip the DSCP and possibly replace it with normal ToS bits on egress traffic leaving my network. Leaving DSCP set is pointless, and could potentially cause problems with some ISPs that use DSCP internally I suppose. Setting ToS bits would seem ideal as most networks still honor it to varying

Hi all, Can anyone show me pointers on how to get this implemented on a Linux box with tc rules? I also want to know, just how efficient is this Algorithm. AFAIK, inbound traffic control can''t really be achieved without losing bandwidth. In some of the howtos'' I''ve read, one guy had to limit his downspeed to 1/2 his bandwidth to actually control it. And he was saying

hi, Is there a way to calculate Gred parameters, given a desired delay (e.g 100ms)? Thanx Ntanzi ____________________________________________________________________________________ Do you Yahoo!? Everyone is raving about the all-new Yahoo! Mail beta. http://new.mail.yahoo.com

Hi, In the GRED queueing discipline of linux traffic control, we can define around 16 Virtual Queues with different RED parameters for each one of these. As far as I think, while applying RED on each of the virtual queues, with the grio option set, quave(the average queue length) of a virtual queue with priority= n is given by the sum of the virtual queues with priority greater than n ... I have

Has anyone ever managed to use GRED and HTB ? Been googling all over the net for hours and did not manage to find any proper implementation. In my case all AF traffic goes into VQ 3 In opalsoft afhtb example traffic goes into VQ 1 & 2 any script will do just fine for me Thanks in advance , Antonio _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

Hi: Execuse me if this has been mentioned before, I''ve looked around the archive but did not find anything about the problem I met. I''m trying to use tcindex to classify the the packet outgoing to one interface. I do as the following : tc q a dev eth0 root handle 10:0 cbq bandwidth 10Mbit avpkt 1500 tc c a dev eth0 parent 10:0 classid 10:1 cbq bandwidth 10Mbit rate

EHLO tc gurus. New to traffic control. Unfortunately, the politicians here in Denmark have decided that a PC is the same as a television set - so anyone owning a PC and internet connection of over 255 kbit/s must pay DKR 2200/year = EUR 300 = USD 400 in television licence fees :-( This is a lot of money for poor students, so we want to offer the students the *option* of limiting their

Hello.. I have a linux box and I want to make priority on traffic generated by my LAN''s computers.. I don''t have a guaranted bandwidth, so I wanna use sfq... I want to make traffic to port 80 , 443 , 25 & 110 PRIORITY 1 Traffic src or dest 192.168.0.2 to make priority 2 And the rest to put it in proiority 3.. I did the following : tc qdisc add dev eth0 root handle 1:

I want to implement a new queuing discipline for the tool tc. The new queuing discipline would support the application of multiple threads on the same queue with different kinds of traffic. Each kind of packet will have its own drop probability but while calculating the average queue length, the no. of packets in the queue will be equal to the sum of the individual no. of packets(of the different
