Hi,<br>
<br>
At the moment, I'm registering 40000 users in FS using ODBC with no
more than 16 registration/sec.<br>
When I do a select in the sip_registrations table, I see that every
sip_user have an expires value equal to something like "1273141208"
even if I'm using an expire value of 3600 in my sip register request.<br>
<br>

<br>
When I look in the sofia status profile, it seems that the correct
expires value is set. Any idea why the expires is not set accordingly
to the SIP REGISTER.<br>
<br>
Moreover, when doing a "sofia status profile internal" with such a huge
subscribers list, the CPU is at 100% and processing no more SIP
messages.<br>
Is there a way to prevent this, by setting for example a lower priority
to CLI request. I already mounted the SQLlite DB in RAM to avoid IO
bottlenecks.<br>
<br>

Hi,<br>
<br>
I already thought about that, as I'm using static IP it could be even
easier. <br>
But how to check network connectivity issue and reroute call to
voicemail asap: call progress timeout ??<br>

Re-loading everything just in case something has changes is a huge
waste of bandwidth and CPU - if you install an intelligent change

Subject: Re: [Freeswitch-users] Registration ODBC feeded by another
registrar proxy<br>
<br>
Hi,<br>
<br>
thanks for your answer and just some details to describe what I'm
looking for.<br>
I have to register 25 000 subscribers, no NAT is involved, each
equipment has its own IP address.<br>
These equipments are registering every 60 seconds on our current
platform, but I can change this parameter if needed.<br>
Equipments are ADSL CPE (router), that's why I'm using 60sec cause
flapping could happen very often with ADSL if the copper line is
crappy. ADSL could be very unpredictable sometimes.<br>
As I don't want to delay too much forwarding to voicemail if a user is
unavailable (network issue), 60 sec was chosen (bandwith is not an
issue). But as I told before, I'm open to your suggestions.<br>
<br>
To Philip, using a single SIP proxy (opensips/ser...) in front of a FS
cluster could be a single point of failure too.<br>
I think that maybe a solution using DNS SRV to distribute the load
across a cluster could do the trick or some kind of LVS (virtual IP
shared across many servers)<br>
XML curl is a good idea too.<br>
To be honest, clustering is a must to avoid a single point of failure,
but FS performance as a SBC are really great even on commodity
hardware, more than 100 CallPerSecond with no transcoding. That's why I
think that a mix with a SIP registrar and FS (and redundancy) could
easily handle my 25 000 subscribers. I did some lab (one or 2 years
ago) with Kamailio registering 90 000 users every 60sec (1500
Registration per second) without any issues.<br>
In my network, 25 000 users are not pushing more than 10 CPS and 500
simultaneous call. I'm not doing VoIP termination.<br>
<br>
At the moment, I'm just collecting data/feedback on what could be done
as I have some time to work on this project, and if going further I
will share the configuration as I did before:<br>
<a moz-do-not-send="true"

(not the best setup, but hope it helps users to begin with FS)<br>
<br>

<div>Hi list,<br>
<br>
was playing with FS 1.0.6 and trying to test the registration <br>
performance of FS. (Yes I know FS is more suited as a B2BUA, but please
<br>
read further :p)<br>
<br>
So I did the following:<br>
- generate one xml file with 20 000 user account like this:<br>
<include><br>
<user id="1"><br>
<params><br>
<param name="password" value="1234"/><br>
</params><br>
</user><br>
<user id="2"><br>
<params><br>
<param name="password" value="1234"/><br>
</params><br>
...<br>
<br>
Then I used Sipp to test how many registration per second could be
fired <br>
to the server (quad core 2.83Ghz).<br>
I setup ulimit variables, and disable nat.<br>
<br>
I got this:<br>
- using SQL Lite: unable to get higher than 80 registrations per <br>
second (in fact it's less than this number but didn't test too much
this <br>
setup), I see a lot of retransmission in Sipp<br>
- using SQL Lite in ramdisk (tmpfs): OK with 80 registrations per <br>
second but not much<br>
- using ODBC and mysql: 130 reg/sec is OK<br>
<br>
With ODBC, above 150 reg/sec I see that FS is stalled to 100-110% CPU,
I <br>
think it's because I'm using only one SIP profile and that SOFIA is <br>
monothreaded for this SIP profile.<br>
If I'd like to register every 60sec, the server has to support at least
<br>
more than 300 registration per second.<br>
<br>
So I'm wondering if I could setup something like this:<br>
- use another SIP Proxy as a registrar and feed the ODBC <br>
"sip_registration database" of FS<br>
- FS will be able to use this database to setup a call<br>
- use FS as the outbound proxy for call routing<br>
<br>
But what about the user params that have been setup in the xml file <br>
above. I think that FS loads the user params each time a user is
registered.<br>
<br>
Comments and advices are welcome.<br>
<br>

rod.<br>
