similar to: [OT] Simulating delay, packet loss to test speex?

Hello! Some time back, I added the Speex protocol to my version of VOCAL (www.vovida.org, VOIP tool). Recently, I also added PESQ (automated voice quality testing algorithm) to my tool and have been running some tests on a clean network. The source file is a woman reading some phrases meant to test various aspects of codecs... Speex has a respectable result of 3.67 Some other codecs I've

Hii All, VLAN is create in manageable switch, like Cisco Catalyst and other vlan cap= able switch. eac port in that switch can be assigned in different VLAN. so,= that switch capable to insert 802_1q to each incoming frame (Please correc= t if its wrong, i just newbie in VLAN).I want build VLAN but i don't have v= lan capable switch. Is possible to create a vlan capable switch using switc=

It does significantly better with a different speaker (the male does better than the female), as well. I'm considering purchasing a commercial PESQ license and wrap the PESQ software in a server application. I could then allow other folks to run PESQ

Hello all, i would like to build a setup to generate VLAN frames (respecting the IEEE 802.1Q standard) for testing purpose. How to configure a Linux bridge for it to become a VLAN switch? Is it possible? What user tool to use for that? brctl? Regards, Louis

Hello! My company makes testing software that, among other things, can be used to generate file-system traffic. In order to better support Samba, I need to make a few changes to the way samba mounts file systems: 1) I need to be able to specify the local IP address for the socket connection. This will allow me to bind different mounts to different local interfaces. This information will

Hello! I'm about to try to integrate SPEEX into the VOCAL project. If anyone has any pointers as to the best way to do this, please let me know. After reading the speex api man page, I have a few questions: 1) To encode, it appears I need an array of floats. If I am playing wav files, what is the best way to turn these into something speex can encode? 2) Are there any commercially

This portion of the RFC is gramatically incorrect and confusing: The RTP payload MUST be padded to provide an integer number of octets as the payload length. These padding bits MUST be all zero. This padding is only required for the last frame in the packet, and only to ensure the packet contents ends on an octet boundary. <p> -- Ben Greear <greearb@candelatech.com>

How about if I sell you a copy of speex. Buy low, sell high seems like a good capitalist plan, and then you could feel good about using Speex! Ben -- Ben Greear

1. I really HATE POLITICS. 2. I think Speex is a great solution to the problem of compressing human speech. 3. Good heavens people can we please stop throwing around words like communist and socialism. 4. Government funded research has done a lot for the US and other countries. Going all the way back to the NACA cowling and airfoils that where vital in the development of airliners and the fighters

We try to disable NAPI to prevent a single XDP TX queue being used by multiple cpus. But we don't check if device is up (NAPI is enabled), this could result stall because of infinite wait in napi_disable(). Fixing this by checking device state through netif_running() before.

Hello, I am creating a configuration where a Redhat server running bridge-tools 0.9.5 will be bridging between different VLANs on the same physical interface (for example: a bridge consisting of eth1.100 and eth1.110). This physical interface is being connected to modern Cisco switches running PVST+. The Cisco switch does not like this configuration as the tags on its BPDUs are being changed

I compiled the latest 2.6.19 kernel and tested it with two 3COM 3c905c fast ethernet interfaces which work fine with vlan 802.1q tagging, but when I have added the eth0 and eth1

Hello, Is it possible with a linux Bow to route différents VLANs, like a router cisco can does ? Thank for your answers Laurent Foucher _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Hi all, I am trying to solve a tiny problem that is trivial to solve using dummynet (FreeBSD). I just want to add a delay of 50ms to each outgoing packet from an interface. This is to simulate a large pool of multiple modem users so I also need to add b/w limits etc (which seems to be easy to do). From the mailing list I could fine 2 qdiscs that can simulate latency : "delay" &

My actual scenario is: -Hundreds PCs in a internal network (fixed IP), divided in +- 6 different subnets -A +- 6 customers with leased lines -A Cisco Catalyst 4006 connecting groups of PCs to corresponding customers (imagine a Call Center company) -Works fine. The problem: Frequently, it''s necessary to migrate dozens PCs from a customer to another. You know, change all IPs and

Hi all, The patch below does four trivial changes and one big change Trivial changes, these are all in br_netfilter.c: - check ar_pln==4 when giving bridged ARP packets to arptables - delete unnecessary if in br_nf_local_in - add more logging for the "Argh" message - add some brag-comments in the file head comment Big change: let {ip,arp}tables see VLAN tagged {I,AR}P packets.
