The SBC Core supports an N:1 mechanism for the SBC SWe platform where up to N active SBC instances are backed up by a single standby SBC instance. On a fail-over scenario, the standby instance takes over and becomes active and the failed active instance becomes standby, once it is up and running.


The maximum value of N is one for Signaling SBC (S-SBC) and four for Media SBC (M-SBC).

For additional details, refer to N:1 Redundancy Architecture.
