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

hmm HFSC ? where can i find more informations and examples about the *linux* HFSC ? http://trash.net/~kaber/hfsc/ does not help here -- _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

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

Hello all. I''ve been struggling to QoS VoIP at our site and have a successful implementation at this point. Basically I had to set aside enough bandwidth for VoIP by placing all other traffic behind an HTB (multiple classes and queues behind it). Everything is fine. Here''s the diagram: ------- | eth | ------- | --------

Hopefully someone has a suggestion on how I might do this...as I can''t figure it out :( I need to be able to set up a group of seperate users who have a "bandwidth pool" they share, but also be able to limit their individual bandwidth as well. Example: I have 5 customers and would like to be able to provide them with a maximum of 256Kbit each, with a CIR of 33%. To do this,

Modification from V2 to V3: Use a more pefect code suggested by Joel. Thank Joel for it. In ocfs2/xattr, we must make sure the xattrs which have the same hash value exist in the same bucket so that the search schema can work. But in the old implementation, when we want to extend a bucket, we just move half number of xattrs to the new bucket. This works in most cases, but if we are lucky enough we

I have voip quality issues I would like to minimize. I have a ~= 3M/384k (Comcast) cable modem and a CentOS based Linux router (SME 7, 2.6.9 kernel) with 5 NAT''d devices (3 PCs "DHCP", 2 Vonage adapters "static 10.10.2.10-11"). The quality problems are audio cutting out and popping. I tried the following (see below) based on a Cookbook example, but I still have

Hi, I implemented queues on some ports with htb by filtering. and to have a constant bw, i defined rate and ceil the same. But while watching the bw''s, I ve realized they may sometimes exceed the defined value for short periods. How could I avoid this situation? I thought that implementing a leaky bucket''d be fine but i m not sure about this and how to do it on tc. I would be

I am a newbie to bandwidth management and trying to manage bandwidth with classbased queuing using HTB (Hierarchical Token Bucket) as this is simple and more efficient. In this process, I am trying to write a config file that helps in managing queuing rules easy. Can anyone help me wiith this. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

Tristan, could you please run your xattr test against it? xs->base used to be allocated a 4K size and all the contents in the bucket are copied to the it. So in ocfs2_xattr_bucket_set_value_outside, we are safe to use xs->base + offset. Now we use ocfs2_xattr_bucket to abstract xattr bucket and xs->base is initialized to the start of the bu_bhs[0]. So xs->base + offset will overflow

in HTB use 2 bucket for manage 2 rate??? first bucket -> keep token for sending with rate second bucket -> keep ctoken for sending with ceil rate Is it true?? may be i''m misunderstand about token/bucket thoery _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Hi, Am sure this is a trivial question but for some reason, haven't been able to figure it out. I want to bucket data in a vector, and then iterate over the buckets. Say the data set is: > cleandata[,4] [1] 26 26 26 26 26 26 26 26 26 26 26 26 61 61 61 61 61 61 61 61 61 61 61 89 89 89 89 89 89 89 180 180 180 180 362 544 544 544 [39] 544 544 544 544 544 544

I''m trying to do some very simple rate-shaping on an interface. I want to limit my 100baseT interface to 7 megs both ingress and egress of the interface. I''ve been hacking my way through the documentation and some examples and I''ve come up with the following configuration for tcng that seems to do what I want. I''m curious if some of the other experts out

I am trying to create my own Token Bucket Filter. However, I have a problem with packet dropping. Scenario : I got two streams 20KB/s each. I got one bucket with rate 20KB/s I put both streams into this bucket. When buffer is full packets need to be dropped. The problem is that only every other packet needs to be dropped in this scenario. Streams are the same so queue looks like that : S1 |

Hi, I compiled the asterisk 14.0.2 to my ARMv5 NAS, however I just have enough time to test it now. But with the default config (I only edited the http.conf), it won't start, but gives the following: Sorcery registered wizard 'bucket' Sorcery registered wizard 'bucket_file' Parsing /ffp/etc/asterisk/sorcery.conf Parsing '/ffp/etc/asterisk/sorcery.conf': Found Cannot

Context: I'm trying to implement support for ASan's unittest suite in CMake. This is ... quite challenging. I think I can get it to work with one significant caveat: it will require manual dependency management. None of the automatic header tracking. I think this is fine in some cases, and not so fine in other cases. Let me explain. It feels like these tests are really comprised of two
