I am using a server with asterisk and I am trying to prioritize voip traffick -- I am a newbie at this traffic shaping, so please bear with me. I used the script below and what happens is thatall traffic in the bulk class stops after a couple of minutes. Also, should I include the ports for rtp in the filter statements with the ports 5061 and 4569? Note I have a fairly big pipe -- supposed to

Hi,All I am using iproute2 to manage bandwith for ADSL router.High,medium,low priority are needed for different protocol port on the ADSL's upstream side,as following: LAN --- |ADSL Router|------WAN When there aren't traffic on the specific priority, its bandwidth should be borrowed by other priorities.But it doesn't work.Here is my script: /usr/sbin/tc qdisc del dev nas0 root

hey guys i am regulating the traffic to & fro by my network through a linux gateway , its behaving strange. i regulated Downlink to 2Mbps & UPlLINK to 500Kbps. both perform well when those are done independent i.e. one at a time but when i do both from a client system ..the downlink however continues at 2mbps but the uplink falls down to 100kbps? is something wrong with my script or

Hi all I am conducting the experiments comparing IP router forwarding delay and MPLS LSR forwarding delay, it is obvious in theory MPLS in Core should be faster than IP, but for small netork (only have several core routers), result show it is not, this is why I want emulate a large IP routing table in one core router. can I do it and how ? right now I use static routing table (by using command :

I need to shape traffic from some IP on one LAN, but I''m in trouble. There is a linux 2.4.26 connected to the Internet (eth0) / LAN(eth1) doing NAT. I''m using VLANs in the LAN Interface, that is connected to a 3Com SuperStack II in a 802.1Q tagged port. I want to create a class that will limit the traffic at 384Kbit/s. I want to create two leaf classes that limit the traffic at

Hello! I have a problem here. I set up a Linux 2.4 machine to do bandwidth limiting for some of our customers. Current setup is something like this: |--------| backbone |-------| |---------| |Internet|225.1-----------225.10|limiter|228.1----228.10|cust. gw2| |--------| | eth0 |-------| eth1 |---------| | 225.20

all: I"m just trying to create a simple rsvp session to familiarize myself with the protocol. I don''t ever get a rsvp RESV message only PATH AND PATH TEAR messages. There is a timeout but i''m not sure whats causing it exactly. Can anyone shed some light on why? All the configs and output are below. Please let me know if you need more information. Thanks.

Hi All, I found 2 unusual behavior with u32 classifier in Kernel 2.4.12. I’ve u32 compiled as module. 1> u32 filter seems not working if there is already some fw filter used for some other class. In order to get u32 working I’ve to delete root class, which in terms delete all fw filters too, and then same command for u32 works. fw is also compiled as module. 2> If I add u32 filter to my

Have a few generic questions about Kom-RSVP 1.) 11:00:05.175 WARNING: timer system overloaded, deviation is 30.080 sec - what timer is this referring to? System time? 2.) What is the relationship between the CBQ class created for RSVP traffic and the CBQ parameter that is in RSVP.conf? - ex. ### cbq qdisc ### tc qdisc add dev eth0 root handle 1: cbq bandwidth 10mbit avpkt 1000 mpu 64

Hi. I want to shape traffic from some IPs in my lan, but I''m w/ trouble. I have a linux box connected to the Internet. In the other side of this box is my LAN. I want to create the following scenario: My root qdisc is attached to a 100Mbit/s NIC I want to create a class attached to this qdisc that will limit the traffic at 384Kbit/s. I want to create two leaf classes that limits

Hi! I just recently entered the wonderful world of the so called "advanced routing" and decided to try and limit the bandwidth of a MASQed network here and ended up in trouble :(. The setup is (as far as I can tell) pretty straightforward. eth0 is connected to the "real" network with a proper IP, and eth2 is 192.168.10.x (the MASQed network). All of it is basicly right out of

Hello all, I am testing CBQ and HTB these days and I got a lots problem which needs your help. It is a little long text :) Thank you! (All my test is based on Redhat Linux9.0) 1.Is isolated of CBQ working? I have read Mr. stef word that he never made cbq isolated work. 2. I have setup an environment to test cbq: one tcp flow which I should protect and a noisy udp flow who will eat much of the

Hello, I have been working on tc class . But when the classid reaches 5 digit , it DOES NOT ACCEPT THAT ... see the example below :: tc class add dev eth0 parent 10:36 classid 10:13310 cbq bandwidth 10Mbit rate 32Kbit allot 1514 weight 3.2Kbit prio 5 maxburst 20 avpkt 1000 bounded See the bold digit !! this command doesn''t work , but if i use with 4 digit then it works : tc class

Hi all, I''m sure I''m soing something wrong here. I am trying to set up a rate limit inside another rate limit. eg. I have a 512K rate limit on a particular VLAN. I am using an IFB so that packets passing through the bridge are counted at each port.(ie the throughput is limited to 512K, not just the traffic in one direction.) This part works OK, but I also want to limit a

Using below configuration multiplied by 3000+ nodes to control bandwidth causes very high kernel cpu usage (99.5%) narrowed it down to the mangle table. Any ideas to do this more efficiently would be appreciated. The mangle table entry (indicated by ***) is sucking all the cpu. I am running RH7.3 kernel 2.4.18-3 and iptables 1.2.5 This setup has worked well for more than 1000 devices but as the

Hi all, I''m having some problems setting up qdiscs on a bridge.The config looks a little like this: ifconfig ifb0 up # Bring up the IFB for this bridge. tc qdisc add dev eth2 ingress tc qdisc add dev eth3 ingress tc qdisc add dev ifb0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8 # Raw qdiscs on each bridge port tc qdisc add dev eth2 root handle 1:0 cbq bandwidth

I want to set the DSCP field of the incoming packets. And then put them in the correct queues.
