similar to: Marking at egress? (DiffServ)

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.)

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 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 |

Hi,All I setup traffic control configuration with HTB this way: 1: root HTB qdisc | 1:1 HTB class rate 1024kbit | /-----+-----+-----+------+-----\ 1:10 1:20 1:30 1:40 1:50 1:60 EF AF41 AF31 AF21 AF11 BE and alloct different bandwidth to these PHBs(queues).So which tool would I use to generate these packets at the same to for

Hi, I am trying to implement a simple scaled-down version of the AF traffic class type. As such I basically want to remark non-conforming AF11 packets to AF13. Here is m script that I have been using on the ingress router of my network: ---------------------------------------- Link=''dev eth1'' Rate1=''rate 800Kbit'' Rate2=''rate 2500Kbit''

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

Hi stef and all I want measure the policy perfomance for video traffic on mpls diffserv network. there are two different polices for video packet 1. Video packets that are marked that are over the limit are to be rejected at the edge router. 2. Video packets that are marked that are over the limit are to be downgraded as best effort and are sent through. Before video enter my mpls

Im experimenting with using a Linux machine with 3 interfaces to operate as a core router. All links and network interfaces are 100mbit. Below is a ascii diagram of the network. (network A) edge router ------>core router---->edge router (network C) ^ | | edge router (network B) I have tried two

Hi all, Another requirement we have is that traffic entering the DS domain be classified then subsequently assigned a (different?) DSCP based upon its classification. For illustrative purposes only let''s say (for traffic entering the DS domain on dev eth0): - WWW traffic would be marked BE - traffic destined for 10.10.10.10 would be marked AF11 - VoIP traffic from 20.20.20.20 would

Hi, There is some extra information in this email! I am working on implementing Diffserv on linux project. I am using suse 8.0 professional kernel 2.4.21. I have the following RPM:iproute2-2.4.7-697.rpm This supports a number of linux qdisc like cbq, htb among many others but it has no support for DSMARK, which I wish to use. Does anyone know of any patch that I could used or any other solution

Hi, I have a problem similar to the previous poster (thread: Virtual network of DomU''s), but apparently not with similar solutions... Situation: - two physical links aggregated to "default0" - dladm create-vlan on default0 with several different vlans - xVM DomU running linux connected to the same vlans when trying to ping the DomU from Dom0, I can see with snoop (in Dom0)

Hi, all. I set up a dht system, and sent a HUP signal to client to trigger the reconfiguration. But i found that the TCP connection established increased by the number of bricks(the number of glusterfsd progress). $ ps -ef | grep glusterfs root 8579 1 0 11:28 ? 00:00:00 glusterfsd -f /home/huz/dht/server.vol -l /home/huz/dht/server.log -L TRACE root 8583 1 0 11:28 ?

Hi all, I am new-ish to Linux tcng and am struggling to find the resources and know how to implement what I need. What I have is a PC with 2 interfaces and a control program on that PC. In the control program I can specify an IP Flow with source and dest IP address, source and dest port, and a QoS class (1-5 which can be mapped to a DiffServ class) - in the control program I want to be able

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 all, First, let me say I''ve been most impressed with how quickly and professionally people on this list ask and answer questions. Next, let me say that with which I need help is properly configuring strict PQ, and gathering certain stats. Specifically: - I need to create a priority queue with four queues (let''s say they are of high, medium, normal, and low priority) - I

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
