Automatic switching to a backup server or route when the primary messaging system becomes unavailable.
Why Failover Matters
Any single server or route can go down, hardware failure, a carrier-side outage, a network issue. Failover is what keeps traffic moving when that happens: rather than every send failing until someone manually intervenes, the system detects the failure and switches to a backup automatically.
How Failover Works
A health check continuously monitors the primary server or route. When it stops responding or fails the check, traffic is automatically redirected to a standby server or an alternate route, with the switch happening in seconds rather than requiring a person to notice and act.
How SMPPCenter Uses This
SMPPCenter applies failover at both the infrastructure level, backup servers behind the load balancer, and the routing level, an alternate carrier route taking over automatically when the primary route degrades or drops.
