Hi<br><br>When i ran the below command on vicidial dialer:<br><br>[root@vicidial2 ~]# tethereal -i eth0 -a duration:300 -w sample.cap<br>Capturing on eth0<br>320167<br>147496 packets dropped<br><br>on net i found: When i ran Acterna PVA-1000 on
sample.cap it showed Max Jitter about 20 % and packet loss and echo as major cause of voice degradation. MQS was also less 2.59 where as it should be around 5.0. are packets being dropped at interface card or at kernel and how to correct it. Machine configuration is given below:
<br><br><br>
<tt>So "1000 packets captured" means, in Tethereal and tcpdump, "1000
packets read from libpcap and processed".</tt><br>
<br>
<tt>What "100 packets dropped" means is that, of all the packets supplied to
the kernel's packet capture mechanism that passed the filter, 100 of
them were dropped because there wasn't enough room in the kernel's
buffer for them; this means that packets aren't being read from the
kernel's capture mechanism fast enough by the application.<br><br>Machine configuration:<br>Linux <a href="http://vicidial2.esselshyam.net">vicidial2.esselshyam.net</a> 2.6.11-1.1369_FC4smp #1 SMP Thu Jun 2 23:08:39 EDT 2005 i686 i686 i386 GNU/Linux
