  • Fast failover for gateway instances
    Patent number: 10938626
    Abstract: Techniques are disclosed for managing gateway switchovers. An indication is received that a primary gateway will be switched to a backup gateway. In response to the indication, a response is made to a periodic health probe that a gateway switchover has been initiated. Incoming data traffic is forwarded from the primary gateway to the backup gateway. Subsequent to an elapsed time delay, a response is made to the periodic health probe that the primary gateway will no longer accept incoming data traffic. The time delay may be based at least in part on one or more of a time interval of the periodic poll and a time to effect the gateway switchover. The forwarding of the incoming data traffic from the primary gateway to the backup gateway is terminated.
