The database is shared over ssh tunnel so it looks to each server as they are using a local database. The goal is to make the service scalable so that we can add more OpenSIPs hosts as the need comes. Also we want to have the system detect if a server has failed and not direct calls/registers to that server. All the servers are in a cloud system (which does not provide Multicast, only Unicast), and they will have both public IP and internal IP associated with them. The problem with the shared database is that the location table has the socket column storing the Internal IP of the OpenSIPs server who did the REGISTER of the SIP client with. I need to relay all INVITE/BYE/CANCEL requests via that server. I have no UDP load balancer to balance the SIP requests, and having the RTP Proxy proxy all audio packets is an extra burden to the design. Our clients register with only one SIP server, there is no configuration to register with a primary and secondary SIP proxy. </span><o:p></o:p></p><p class=MsoNormal><span style='color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span style='color:#1F497D'>What we worry about is putting one OpenSIPs server acting as a load balancer or dispatcher, is that we’d be then again dependent on one OpenSIPs server. That dispatching / load balancing OpenSIPs server should be also backed up by a fail over server. I’ve looked into some, mostly academic, papers on how they did their load balancing and fail over. </span><o:p></o:p></p><p class=MsoNormal><span style='color:#1F497D'> </span><o:p></o:p></p><div><p class=MsoNormal><span style='color:#1F497D'>Tuomas Kaikkonen</span><o:p></o:p></p><p class=MsoNormal><span style='color:#1F497D'>Software Developer | Twisted Pair Solutions</span><o:p></o:p></p><p class=MsoNormal><span style='color:#1F497D'>3131 Elliott Ave, Suite 200, Seattle, WA 98121</span><o:p></o:p></p><p class=MsoNormal><span style='color:#1F497D'>Tel: (206) 812-0732</span><o:p></o:p></p></div><p class=MsoNormal><span style='color:#1F497D'> </span><o:p></o:p></p><div><div style='border:none;border-top:solid windowtext 1.0pt;padding:3.0pt 0in 0in 0in;border-color:-moz-use-text-color -moz-use-text-color'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'> Bogdan-Andrei Iancu <a href="mailto:[mailto:bogdan@opensips.org]">[mailto:bogdan@opensips.org]</a> <br><b>Sent:</b> Tuesday, March 19, 2013 8:01 AM<br><b>To:</b> OpenSIPS users mailling list<br><b>Cc:</b> Tuomas Kaikkonen<br><b>Subject:</b> Re: [OpenSIPS-Users] Load Balancer module for REGISTER as well as INVITE?</span><o:p></o:p></p></div></div><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal style='margin-bottom:12.0pt'><tt><span style='font-size:10.0pt'>Hi Tuomas,</span></tt><span style='font-size:10.0pt;font-family:"Courier New , serif ;","serif"'><br><br></span><tt><span style='font-size:10.0pt'>The LB modules is only for CALLs - it understands by +1 load only a call.
