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 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

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

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 qdisc. 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

Hi all I have a trouble configuring the qdiscs, when I indicate the "perturb 10" option to tc, i gives me this error: tc qdisc add dev eth0 parent 5:1323 handle 1323 sfq perturb 10 RTNETLINK answers: Invalid argument if I don''t put the "perturb 10" option, it works. another question is about iptables, when I indicate the " --set-mark" option: iptables -t

Group, I am reading about tc (traffic control) and willing to get my feet wet. As requirement, there should be HTB compiled in the kernel. I grabbed a Mandrake 8.2 distro, and didn''t installed the kernel source. Anyone knows if the HTB is compiled in Mandrake 8.2, or point a way to find that out? I tried to read the /usr/src/kernel.xxxxx/.config file, but it doesn''t exists.

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

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,

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,

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

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.)

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 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

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

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
