DSCP, ToS and Egress
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

Marking and remarking of incoming traffic
I can use DSMARK to mark on the Egress side. Is there a way to
mark/change the DSCP value of an incoming packet on the ingress side?
Thanks.

TOS bits, DSCP, Asterisk & Polycom
Has anyone figured this out yet?
Lots of places say to add the following
to sip.conf of an Asterisk 1.2 system
(current production machine/Asterisk as root):
tos=0xB8
(Hex B8 = Decimal 184 = Binary 10111000)
or if you are running Asterisk v1.4 or newer:
tos_sip=cs3 ; Sets TOS for SIP packets.
tos_audio=ef ; Sets TOS for RTP audio packets.
tos_video=af41 ;

using tc to drop packets based on the diffserc or tos value
Hi all,
I am wondering if anyone can help me to resolve a problem.
I am trying to use tc command in linux to drop udp

I am able set diffserv value successfully in the udp packet
using command:-

Problem: DSCP target
Hello everybody,
I have tried several iptables versions (from 1.2.4 to 1.2.6a) to
mark outgoing packets (change the DSCP field) with no success.
#iptables -A OUTPUT -t mangle -d 10.0.0.3 -j DSCP --set-dscp 0x2
iptables v1.2.6a: unknown arg ''--set-dscp''
TOS target is working fine, but I want to create different codes
for EF and AF classes in a diffserv

Problem with iptables with -j TOS and MARK
Hy,
I would want to mark the packets that are entering in a machine, with a
mark for using diffserv with DSMARK.
My machine has 2 interfaces, a ethernet and a wireless. The ethernet
interface is eth1 and the other is wifi0.
Firs, I would want to test that I would be able to mark the tos of the
paquets that I would be receiving, for this I write in the console of my
linux:

QOS / Cisco / Asterisk
We're trying to PQ (Priority Queue) packets on a Cisco using ACL's. What
we're trying to avoid is hardcoding the IP address in the ACL. We were
trying to match by TOS set by Asterisk however it seems we've run into a
snag where the packet TOS tends to get reset somewhere on our network.
Has anyone had this issue? We're running Cisco everywhere inbetween
(even the switches). Is

EF & AF filters with HTB
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

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

Linux QoS to support LLQ and WFQ
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

WFQ substitue
Hi,
I wanted to implemente WFQ, but it is not implemented on tc.
Is there any way of making something like WFQ with which is implemented on
tc??
What I exactly want to do, is to select flows by IP and port destination, and
priorize them, but I don''t need (and don''t really want) to fix any rate...
Has anyone got any clue???
Thank you
Bye

QOS inquiry:WFQ?HTB?DRR?
Hi,
I used HTB3.6 on Linux to control traffic.It seems that HTB uses DRR(Dificit Round-Robin) algorithm.I heard that it is difficult for DRR to get a delay bounded and WFQ is better than DRR.Is that right?So,how to implement WFQ in Linux?
Thanks a lot!

Very simple traffic shaping script for H.323
Hello -
What I want to do seems very simple - I want to make sure any H.323
traffic gets processed before anything else entering or leaving this
network. The network has a videoconferencing device on the LAN at
192.168.16.4. A Linux firewall NATs an external IP Address to this
internal address and I have appropriate SNAT and DNAT rules that work.
The NAT and connection tracking rules all work

RTP/SIP traffic prioritization and Linux issues
Hello, all. I've stumbled across what seems to be a traffic

We had planned to use expedited forwarding for our RTP and perhaps our
SIP packets. Our plan was to set DSCP to 101110 (by the way, I think

Scheduler Mechnisms!
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
