May a suggest a change filter developed if this really is needed?<BR>
<BR>
Re-loading everything just in case something has changes is a huge waste of bandwidth and CPU - if you install an intelligent change filter you would be down to a few entries changing.<BR>

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 href="http://wiki.freeswitch.org/wiki/SBC_Setup">http://wiki.freeswitch.org/wiki/SBC_Setup</A> (not the best setup, but hope it helps users to begin with FS)<BR><BR>regards,<BR>rod.<BR><BR><BR><BR><BR>Le 03/05/2010 19:54, David Ponzone a écrit :

<DIV>Rod,</DIV>
<DIV><BR></DIV>Registering every 60 seconds is a bad idea, and this should not be justified.
<DIV>You should register every 1800 seconds and send a NAT keepalive every X seconds.</DIV>
<DIV>X should be slightly lower than the NAT UDP timeout of the router in front of the phones, if the phones are behind NAT.</DIV>
<DIV>If the phones are not behind NAT, NAT keepalive is not necessary.</DIV>

<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>regards,<BR>rod.<BR><BR><BR><BR>_______________________________________________<BR>FreeSWITCH-users mailing list<BR><A href="mailto:FreeSWITCH-users@lists.freeswitch.org">FreeSWITCH-users@lists.freeswitch.org</A><BR><A class=ecxmoz-txt-link-freetext href="http://lists.freeswitch.org/mailman/listinfo/freeswitch-users">http://lists.freeswitch.org/mailman/listinfo/freeswitch-users</A><BR>UNSUBSCRIBE:<A class=ecxmoz-txt-link-freetext href="http://lists.freeswitch.org/mailman/options/freeswitch-users">http://lists.freeswitch.org/mailman/options/freeswitch-users</A><BR><A class=ecxmoz-txt-link-freetext href="http://www.freeswitch.org/">http://www.freeswitch.org</A><BR></DIV></BLOCKQUOTE></DIV><BR></DIV><PRE><FIELDSET class=ecxmimeAttachmentHeader></FIELDSET>
