Forcing delay and setting bucket size
Hello all, First I''ll state my final goal - In case someone knows an existing piece of code that does the trick: To use Linux with two network interfaces as a router and link simulator with the following features: 1. Limited bandwidth 2. Specified propagation delay which affects each packet going out of an interface 3. Limited bucket size (send buffer) for each interface. I know how to

Using tcng to create a basic DiffServ router
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

QoS IP precedence and Diffserv combination
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.)

W(RED) curve implementation in Linux DiffServ
Hi! I have a Traffic Control/QoS question about the W(RED - Random Early Detection/Discard) curve implementation in the Traffic Control environment. Is this the right curve for RED - has it been tried to be implemented in the Traffic Control environment?: An Analytical RED Function Design Guaranteeing Stable System Behavior: http://www.ist-mobydick.org/publications/aqm_iscc2003.pdf Citat:

Something about 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

About Diffserv on linux
Hello Merry Christmas, I want to know whether there are anyone who has been familiar with the source code in linux kernel about Diffserv, I think i have met lots of troubles. A simple problem: if we use the command ''tc add class'' to add a class, do you think it will be in a Interrupt enviroment? That is, if i want to add a class or qdisc using TC, are there any interrupts int

What happened to diffserv?
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,

Re: Diffserv on Linux 2.4.21 (DSMARK problem)
Hi guys, 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 so that use of dsmark is possible. Traffic

DiffServ Marking
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

Marking at egress? (DiffServ)
Hi all, Supposedly my router is itself streaming traffic to clients. Is it possible for it to mark its packets before going through dsmark?? I have gone through the examples in iproute2/examples, i noticed that there''s always an ingress and egress of which these are 2 different dev. Is it possible for before ingress and egress be the same dev?? I tried the script below but

About Diffserv on linux!
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:

Diffserv Research Network
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

RFC: [PATCH] Add TCP congestion control and Diffserv options
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

FW: Some queueing disciplines that I wrote.
Dear LATRC and devotees, I have developed some Linux queueing disciplines. I developed them for my masters project. You are free to use or distribute my work. Here is the abstract from my dissertation:- This is a project to implement a Mice and Elephants queuing discipline on Linux. My project has three aims. The first aim was to produce a prototype Mice and Elephants router

Best method for filtering ACKs?
Hello, I''m wondering which of these filters is the best method for filtering ACK packages to achieve lowest delay possible on a dsl-link. This one ist from the wondershaper from the lartc-site: /sbin/tc filter add dev $EXTIF parent 1:0 protocol ip prio 0 u32 \   match ip protocol 6 0xff \   match u8 0x05 0x0f at 0 \   match u16 0x0000 0xffc0 at 2 \   flowid 1:10 Thats a suggestion
