Hello, This is a question about diffserv on linux. We know, there is a file sch_dsmark in linux source code. Now, i want to add something in the function dsmark_enqueue, for example, i want to add a function which can add a class and queue automately in dsmark_enqueue. That is, not using the command tc. After adding one, it works well, but when add the second one, there is a kernel panic:

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

I''m trying to find up to date information on diffserv, and it seems like either nobody is using it, or nobody is talking about using it. Is there some good site for information about using diffserv with new kernels? The last update on diffserv.sourceforge.net is in 2001, and most of the mailing list results are from that time. Has everyone moved on to something other then diffserv,

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

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

In the bufferbloat age, anything that can make for a kinder, gentler bulk transfer protocol seems desirable. This add support for user and server selectable congestion control algorithms. As examples: --congestion-alg=lp # For the tcp-lp algorithm on the command line Or in a subsection: [mystuff] congestion alg = westwood # for a wireless connection And diffserv support: --diffserv=8 for

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

Hi, I''m interested in prioritizing all packets with the SYN bit on, both with and without the ACK bit on (but specially the SYN ACKS). I am checking is the use of Diffserv. From a paper I read I understood that when Diffserv is on, all "Control Traffic", including TCP SYN-ACKs, gets by default into "band 0" of Diffserv, the highest priority out of 16 bands. If true,

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 Everyone, Merry Christmas. I hope everyone has a enjoyable and relaxing holiday season. I myself will be going bushwalking for a couple of weeks so I won''t have any access to the internet. I''ll be back to work on the 11th of January so please don''t think I''m ignoring your emails. I''ll get to them all them. Merry Christmas and a happy new year.

It's the day before Christmas here in Sweden, actually the night before at this time... We celebrate Xmas on the 24th, so I'm about to log off and switch my Asterisk into "merry-christmas-mode" with the yet undocumented CLI command "frosty-mode on", a mode where the PBX will connect all incoming extensions to the "ho-ho-ho" sound file and then randomly pick a

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

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

Hi all, We are a group of research students and working on IPv6 QoS aware Grid. >From our set of experiments we have a particular case: Suppose a host A want to initiate traffic of some kind to host B, where A and B are connected by two intermediate routers wherein there can be other connections from the router. Our needs are as follows 1. We assume that routers are Diffserv routers and

hi, I received this e-mail which contains a "ballad", at first I thought it was junk mail, but then I read through it, for the EE members of this list, it may be quite humorous. I don't know if the ballad is original, but at least it's the XMAS season, so it's something to lighten up your day, eh? -samudra """ How the Ground Loop Stole Christmas
