Zixi's push redundancy configurations includes an alternative host, which provides a secondary redundant target with automatic failover when the primary becomes unreachable.  Once the failover has occurred, the system remains in the secondary target secondary delivery state until a further interruption occurs, such as further connection loss or a stream being restarted by the user.

PUSH Transmission Retry Timing

When planning a high-availability Zixi deployment it is important to consider timing issues. The various types of redundancy configurations offer different retry timings, which are critical to calculating the overall video dropout at the target. Based on the latency settings that have been configured, Zixi Broadcaster acknowledges disconnection after a connection loss that exceeds the latency period and then retries to establish a connection.  The The cause of the connection loss also determines the time it takes for Zixi Feeder to acknowledge a drop. This can take up to 25 seconds in the worst case scenario.    Latency Considerations
