Hi Faisal,<div><br><div>Can you copy/paste the stats of "ifconfig eth<i>N</i>" on which traffic is terminating.

Hi Faisal,<br>
<br>
Let me comment a bit on the loss at software - packages can be
discarded at TCP/IP stack level (by kernel) if no application is
reading the data (or no reading as fast as the data comes).<br>
<br>
You can check on this (if opensips is able to process all incoming
traffic, without having the kernel to discard data because of full
buffering on sockets) via some statistics from the NET class :<br>

<br>
An overall idea over the load in opensips (if you have idle
processes or not) can be monitored via the LOAD stats:<br>

<div>Hi
Everyone,</div>
<div><br>
</div>
<div>I
am facing huge <span style="color:rgb(54,99,136);border-bottom:2px dotted rgb(54,99,136)"><span style="border-bottom:2px dotted rgb(54,99,136)">packet
loss</span></span> in my server, so I am here
to share with you some of the output of packets
losses that you can see in attached image.
Secondly I have few questions that I want to
discuss with:</div>
<div><br>
</div>
<div>1.
How can we reduce the packet loss to a minimum in
an asterisk server, I mean I just want to know
more detailed info about packet loss reduction.</div>
<div><span style="font-size:10pt">2. I am calculating
packet loss following that link </span><a rel="nofollow" href="http://www.linuxjournal.com/article/9398" style="color:rgb(35,71,134);outline-width:0px;font-size:10pt" target="_blank"><span>http://www.linuxjournal.com/article/9398</span></a> where
there is written that 20% loss is acceptable, but
if you see the attached image what will be your
conclusions about packet loss here?</div>
<div>3.
At last but not least I just want to know the
responsibilities of the software & the
network, I mean how much software or network is
responsible for packet loss?</div>
<div>4.
What are the best possible ways to reduce the
packet loss to a minimum extent?</div>
<div><br>
