similar to: IAX2 trunking: codec bandwidth comparison notes and results

This is not specifically on-topic for Asterisk, but I have found on many occasions while working with Asterisk that it would have been very handy to be able to measure, with some precision, the bandwidth being used by a particular host, port, or combination of the two. So, I went searching for various tools, none of which were what I wanted. They either were too clever, or too limited in

Hi, I am looking how to setup speex codec in codecs.conf for 8 Kbps and 6 Kbps. In config file are many parameters for setting. I don't know what is need to change for narrowbad like 8 Kbps and 6 kbps. Any suggestion? [speex] ;0-10 quality => 4 ;0-10 complexity => 4 ; true / false enhancement => true ; true / false vad => false ; true / false vbr => false ; 0 = off, otherwise,

Hi, I am running HTB and using the following command to get rate and pps statistics: tc -s class show dev eth0 However what I am seeing is that if I run the command over and over again, I see the sent bytes and sent packets increment however the rate and pps have the following issues: 1. The rate and pps values only seem to update after every 15 seconds 2. They do not show until about after

Hello, list members, can i limit pps rate with linux? How? -m limit does not fit, as i understood: it can help with low rates only (is that true? any suggestions?) Thank you, -- _,-=._ /|_/| `-.} `=._,.-=-._., @ @._, `._ _,-. ) _,.-'' ` G.m-"^m`m'' Dmytro O. Redchuk

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 would think so, but I might have missed something. <p>Here is my IceS2-config - with this one, the problem manifests after 2 minutes of playing, and the client is disconnected after 3 minutes. I have tried tweaking bitrate, quality,

This mail depends upon the fact that I don't have a couple of good earphones ;-) I read in the site that q=6 is a very high quality, but does it contain perceivable differencies from the original? (for 95% of people, of course). I also found q=6 to produce files slightly bigger (1/10 bigger) than those produced with lame VBR q=2 (about 192 bps on average). I always thought LAME VBR q=2

Hi I''ve patched net-mrtg http://www.net-snmp.org/ with http://x-ray.prokon.cz/data/snmp/ sucefully Also I''ve copied QOS.TXT to /usr/local/share/snmp/mibs when I make a normal use of snmp, with mrtg in order to monitor all traffic on eth0 and eth1, it works OK. But, how must I do in order to get monitor for a specific class ? If I make a snmpwalk (like README suggest), I get

I resurrected these patches after prompting from Andy Lutomirski's recent patches. I put them on the back-burner because vring_bench had a 15% slowdown on my laptop: pktgen testing revealed a speedup, if anything, so I've cleaned them up. Rusty Russell (3): virtio_net: pass well-formed sgs to virtqueue_add_*() virtio_ring: assume sgs are always well-formed. virtio_ring: unify

Hi all! I installed icecast & ices (from CVS) Enerything runs, but with some problems: When I connect to the server (with XMMS or MPlayer) the buffer runs empty very quickly, causing interruptions. My "server" is an old Pentium 120 with 64MB RAM ,a HD of 8G and an ethernet NIC. (I know it isn't much, but I'm tired of taking my CD collection to work.) I ripped the tracks in

virtqueue_add() populates the virtqueue descriptor table from the sgs given. If it uses an indirect descriptor table, then it puts a single descriptor in the descriptor table pointing to the kmalloc'ed indirect table where the sg is populated. Previously vring_add_indirect() did the allocation and the simple linear layout. We replace that with alloc_indirect() which allocates the indirect

hi how to check the data rate on the nic card in centos i.e, at what speed the data is transmitted and received on ethernet interface in terms of kbps or bps any command is available in centos 5.1 regards, Gopinath M -------------- next part -------------- An HTML attachment was scrubbed... URL:

I'm not an expert either, but I see people choosing iLBC over speex all the time with asterisk; partly it's because they have more market share in hardphones, and partly it's because of marketing and such. (another reason is that iLBC source is included in asterisk, and speex is only compiled in if you have the speex development stuff on your machine when you compile

Dear All, Would you guy have any advices concerning how to get some data like queue length, pkt size, and so forth, from the running queue. Right now, I modified the queue disc to print out some info I want using printk() and use syslogd to catch those info up. The problem is, in burst, syslogd can''t catch all the msg the queue sent out. Are there any standard or better way to

In the precompute_partition_info_sums_ function, instead of selecting 64-bit accumulator when the signal bps is larger than 16, revert to the original approach based on partition size, but make room for few extra bits to not overflow with unusual signals where the average residual magnitude may be larger than bps. It slightly improves the performance with standard encoding levels and 16-bit files
