similar to: DSCP marking

Hi, I want to setup core routers to do both DSCP marking and to get the DSCP and forward packets based on DS field. I don''t want to separate DSCP marking to be done only at the edge routers. I know that dsmark is both used for DSCP marking and for getting the DSCP and forwarding packets according to DSCPs. In my case, since I want to do both of these I need two dsmarks.(?) I am not

I am trying to compare the behaviour of the Linux DiffServ implementation with that of Cisco, in DSCP remarking for traffic policing. As I understand it, the DSCP is marked at the egress interface (parent queue), based on the class that packets are in. I am looking at what happens at an inter-AS boundary. DSCP marked traffic coming into the Edge Router need to be policed and remarked: e.g. EF

Hi fellow traffic-shapers, I am implementing a Diffserv CORE router using Linux kernel 2.4.18. I used this excellent website (http://www.opalsoft.net/qos/DS-38.htm) using AFHTB as a starting basis for my EGRESS diffserv implementation - and all works great so far!!! But my project has an additional requirement. There are services running locally on the router which are sending/receiving IP

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

Did anyone ever answer this one?

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 ;

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

Hello list, I need to set Voice QoS and SIP QoS for YeaLink. The possible values are 0 ~ 63. With Grandstream I can fill in DiffServ 46, which is EF. That's what I want. With Snom I fill in 184, which corresponds to EF or DSCP 46 (according to their wiki) But what value do I want to fill in with this YeaLink ??? This is a conversion table :

Hello, As it is well know that CBQ is the class based queue. But i am confused on the word "class" now, especially it is used in Diffserv. IMO, different classes should mean that there are different kinds of traffics, so the class should be difined by the parameters (such as bandwidth, priority..) the traffic wanted. That is, using cbq we can define different kinds of traffics which

I want to set the DSCP at the ingress of the router. I tried the following: iptables -A OUTPUT -t mangle -d 10.10.10.12 -j MARK --set-mark 1 tc qdisc add dev eth0 handle ffff:0 ingress dsmark indices 64 set_tc_index tc class change dev eth0 classid ffff:1 dsmark mask 0x3 value 0xb8 tc filter add dev eth0 parent ffff:1 protocol ip prio 1 handle 1 fw classid ffff:1 But the DSCP

I want to set the DSCP field of the incoming packets. And then put them in the correct queues. I can mark the packets: iptables -A OUTPUT -t mangle -d 10.10.10.12 -j MARK --set-mark 1 tc qdisc add dev eth0 handle 1:0 dsmark indices 64 set_tc_index tc class change dev eth0 classid 1:1 dsmark mask 0x3 value 0xb8 tc filter add dev eth0 parent 1:1 protocol ip prio 1 handle 1 fw

Hello, As we know that there are four kinds of AF in diffserv architecture, and each kind has three different priorities. So, there are 12 different kinds of AF, is it right? Of course, each AF has its recommended DSCP value. Then, we know the AF is classified into four differnt classes, such as AF1, AF2, AF3, and AF4. But in a Diffserv domain, and in the core router, there will be a classifier

Hello, I am writing a routing daemon that is able to assign different gateways to a destination address for different classes of service. Multiple DiffServ Code Point values are mapped into a single class of service. I have accomplished this by using the iptables MARK target to label each packet with a class of service value and then using ''ip rule add fwmark'' to have each

hi, i am currently working on a project on "design of diffserv testbed in linux". i am using tc utility of iproute2 for it. The qdisc dsmark used for marking the DS codepoint at the first hop router makes number of classes depending on the indices given in the command. But i am not clear how at the first hop router does scheduling takes place. what i mean is if i have two flows, whose

Hi, what would be the easiest way to mark packets for AF. For example ingress www traffic being marked as AF31? thx jason _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Hi there LARTC, We are running a set of three systems for semiconductor technology, and would like to finalize our work in getting them to interoperate properly, but have run into some issues that touch on the very fabric of TCP/IP expertise. Iptables has already been used to solve "part of this", can we somehow use Diffserv capabilities to acheive the aims of modfiying packets such
