[OpenSIPS-Users] Binary interface: usrloc replications - restore registrations after node restart

[Liviu Chircu]

Hi, Ewgeny!

The usrloc binary replication is only the first step in the direction of 
an horizontally scalable OpenSIPS cluster. It is designed to provide a 
hot-backup registrar, through the use of a Virtual IP.

To answer your questions:

1) with usrloc binary replication, if the primary machine reboots, the 
VIP will automatically switch over to the hot backup, and the SIP 
registrar solution will continue to work. Once server 1 comes back 
online (in secondary mode) it will gradually become up-to-date with 
server 2 (current primary), within a couple of hours.

2) dialog replication is currently implemented in a similar manner, with 
a hot backup, and no need for an SQL database in order to keep real-time 
information.


We are currently working on providing a distributed SIP registrar 
solution in the upcoming OpenSIPS 2.2 LTS. You can read some of the 
discussions around it here [1]. Questions / suggestions are welcome!
