Hi all, It is my understanding that with HTB, the rate and the ceiling are divided over the elements of the class. E.g. using a rate of 100 kb and a ceiling of 2000 kb for a class with 10 elements on a 100Mb NIC, the effect of the ceiling will be that if all elements are generating their maximimum possible trafic they will be effectively limited to ~ ceiling / number of elements, in this case

Hi All, I''ve been trying to get a bit of a grip on disk i/o for our Xen set- up. We''re dealing with server workloads that can, at unexpected times, become seriously io-bound, up to the point that a single guest can cannibalize the available throughput of the fibrechannel array. Since we''re dealing with a shared medium and multiple Xen hosts, I''m

Hi Experts, I am new to R, using following sample code for capping outliers using percentile information. Working on large data (30000 observations and 150 variables), loop I am using in the below mentioned code for detecting outliers and capping to upper /lower percentile value is taking much time for the execution. Is there anything wrong with code, can anyone suggest improvement in the script

Hi All, I''m using HTB to shape traffic, a little like this: tc qdisc add dev eth2 root handle 1:0 htb tc qdisc add dev eth3 root handle 1:0 htb tc filter add dev eth2 parent 1: protocol 0x8100 prio 5 u32 match u16 3000 0x0fff at 0 flowid 1:1 action ipt -j MARK --or-mark 0x01000000 tc filter add dev eth3 parent 1: protocol 0x8100 prio 5 u32 match u16 3000 0x0fff at 0 flowid 1:1 action

Hello, I''m still new in using tc...I wanna ask... 1. what is the difference between classless and classful qdisc?? when I made a qdisc, are I must create both of that qdisc...??? 2. what is the difference beetween three of the classless qdisc in linux redhat 2.4, sfq pfifo and tbf if I using the htb classful qdisc ??? because when I use htb classful qdisc it means I made a qdisc that

I''m trying to simulate a satellite link to a Linux server to test application performance. I haven''t used any of the tc stuff before, but I blandly assured people it would be "easy" to set up a simulated long thin pipe on a spare network interface. However, now that I''m exploring, it''s proving quite difficult. Let me start with the general question

Hi all, I have an average 2mbit multicast stream that once in a while bursts high (up to 20mbit/s) in short periods (about 200ms). Could anyone please help me with directions using tc for configuing leaky bucket shaping to this stream? I have a 5mbit/s ceiling. My system is running gentoo linux 2.6.14, and I have compiled in all QoS modules. Thanks. Oivind

Dear all, I am trying to set up multi-user traffic control. In short, I want each user to be hard limited to 128kbit download and 64kbit upload. On top of that, I want interactive traffic (ICMP, ACK packets, SSH, etc) to be prioritised to minimise latency. It sounds like it ought to be done with a classful qdisc but I don''t really know what I''m doing. I think I want

Hi, I am a newbie to LARTC and to this mailing-list. I have read through the Linux Advanced Routing & Traffic Control HOWTO many times, trying to understand Classful Queueing Disciplines (and in particular CBQ). I have some suggestions that I think will help to make the HOWTO more understandable. Suggestions ========= (1) In section 9.4 (Terminology) the definition for

I''d like to implement something like SFQ, but with a cap of a rate per flow. Essentially, I''d like to be able to limit citrix connections to 30KBps without having an overall traffic flow cap for all citrix connections. Slightly preferable to this would be something that would actually work per flow instead of the stochastic algorithm. Is this possible? Thanks, Bill --

Hello, I am using the IMQ with iptables (latest versions) and asking all packets to be enqueued to IMQ0 from both prerouting and postrouting (using different iptables rules to mark different streams). When I do this I get the kernel saying: "Dead loop on netdevice imq0, fix it urgently!" and communications stop intermittently. If I remove the jump from either preroute or postroute it

OK, I''m stumped. I''ve read through most of the LARTC HOWTO and have yet to find a basis for what I need to accomplish. I have a Linux box that controls access to and from the Internet at my workplace. We have a number of remote employees that connect via PPTP and IPSEC to the office''s internal network. Some of these remote employees are currently using SIP phones.

Hi all, I previously mailed this list explaining that I been given the task of implementing a dynamic traffic shaping scheme on an existing network. I was looking for guidance on how I should approach this but unfortunately I was unable to provide much information about the existing traffic shaping system. I have recently obtained the existing tc scripts though and was hoping someone could help
