1. HFSC have 4 curve such sc, rc, ls, ul and 1.1 In leaf class can specify rc for guarantee service (bandwidth and delay) and If want to sharing fairness exceess service, we must specify ls and ul curve too (ls curve with paramater m2 specify at lease sharing bandwidth in that class will receive and ul curve mean maximum bandwidth in that class will receive) so i''m doubt .. about if i

HTB versus HFSC, both qdisc offer the same kind of service, if you want to see comparative test results, go to http://www.rawsoft.org at the line "TEST RESULTS" you will find the results for a sharing test and a burst test. You will see that both qdisc are good. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

Dear Community, sorry for the somewhat dumb question. Maybe someone has any pointer to how to setup the RED queue to mark pakets with ECN. In particular what are appropriate parameter settings for limit, min, max, etc. All my trials end up with either "RTNETLINK answers: Invalid argument", although the command line (at least for me) looks fine in regard to what is said on the

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

I''m using HFSC to limit bandwidth for our wireless customers. However, I''d also like the bandwidth prioritized based on packet type. This is what I''m trying right now, and I''d just like some input from anyone out there knowledgeable in this on whether it does what I want it to do: Eth1 -> HFSC ........|-> HFSC (User1) (Min 512 Kb, Max 1024 Kb, Burst 1536

hi all, long time since i posted on the list. just wondering if anybody has played around with hfsc and if so could he/she share their info on it thanks adrian -- To mess up a Linux box, you need to work at it; to mess up your Windows box, you just need to work on it. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

Im using a Linux machine with standard pc hardware with 3 seperate PCI network interfaces to operate as a DiffServ core router using Linux traffic control. The machine is a P4 2.8ghz, 512mb RAM running fedora core 3 with the 2.6.12.3 kernel. All links and network interfaces are full duplex fast ethernet. IP forwarding is enabled in the kernel. All hosts on the network have their time sychronised

Hello All, I am trying to prioratize VOIP traffic from data. The follwing link says that HFSC is better than HTB for shaping VOIP traffic. http://www.voip-info.org/wiki-QoS+Linux+with+HFSC I am in search of good documentation to start with HFSC, I am unable to understand the parameters used. I "googled" a lot to find on how to use HFSC, but no luck. Can anyone of you get me a link To

Hello, I have a request for an additional header. This header is needed to inform the client of the burst it is going to receive. Why ? This header could be very usefull for the streaming-client to have an idea of it's delay, and (much more important) to be able to do early-on streaming. The question is not on how to implement this in code (probably send the header in the

some body can advise me about how to create burst traffic two type is 1. ICMP burst traffic (i need to create general and normal data burst traffic but i don''t have any idea to do it) 2. Real time traffic (i think may create by open real-time streaming with a big file from real-time server but i don''t sure it will work!) thank you raku

Hello, I have finally managed to understand HFSC up to a level which allowed me to create a QoS script which maintains low VoIP latency while running stuff like eMule. Unfortunately, HFSC seems to have a severe bug. Why do I consider this as a bug defenitely? Well, my script runs without any errors, then QoS works perfectly for some hours, no error messages in kernel log. Then randomly the

This is one of my test classes: class htb 1:10 parent 1:1 prio 0 quantum 2048 rate 160Kbit ceil 400Kbit burst 1803b/8 mpu 0b cburst 2111b/8 mpu 0b level 0 Q1: where does "level 0" stand for? Q2: where does this b/8 stand for? Q3: this is on a i386 platform, so timer resolution should be 10mS. According to the doc the minimal burst should be 10mS*160Kbit=1600. Why is it 1803? Q4: I

I have a lot question about tc-command because now i''m doing research to compare performance between HTB and  HFSC so i''m doubt a lot thing and your reply are so very helpful to me ... My question is In HTB tc command question 1. I''m use opensource (Mastershaper) for help to config traffic control but when i''m try to config HTB, I''m doubt about

Hi, Is it possible to attach another qdisq under a HFSC classfull ?

Hi All, I''m trying to create a contended section of bandwidth using IMQ. I have the imq0 device up and running, with traffic passing through it. Firstly, I need to throttle the entire device imq0 to 2mbit/s. I would then like to add throttle rules for individual IP addresses, allowing them to pass up to 512kbit/s each, as long as imq0 has not reached its 2mbit/s. The configuration

Thanks Karl- Setting the burst-size to 0 does indeed disable Burst-on-Connect. FYI: I have verified that disabling Burst-on-Connect allows VLC Player to play Icecast2 streams. I am notifying the VLC developers of this, so hopefully they can support Burst-on-Connect Icecast2 streams. SHOUTcast burst seems to work just fine, so maybe it won't be such a big problem to fix. Any other

This is a question about the use of the Cox proportional hazards model to analyze event histories. I am looking at the responses of sympathetic nervous system activity to a stimulus. The activity I observe is a burst that can only occur once per heart beat cycle (e.g., a binary count). Typically bursts occur in 60-80% of the heart cycles * sensory stimuli can modify these burst probabilities.

I am trying to narrow-down a problem with VLC Player and I would like to temporarily disable burst-on-connect. I have set this to 0, but it doesn't seem to disable. <burst-on-connect>0</burst-on-connect> <burst-size>65535</burst-size> http://stream.orban.com:80/eval Any ideas? Thanks. -greg.

Hello, I just found the great howto and started shaping my internet connection. The howto''s last update is a liitle in the past now so I have some questions about how things are done the best way nowadays ;-) To ensure a stable and low latency voip communication I added an HFSC qdisc to device ppp0 (1 Mbit SDSL). There are two classes (by now): One for SIP and RTP and one for the
