Owl Failover Service (OFLS) is an optional software application that uses a pair of Owl hardware devices to create a high availability solution for UDP streaming. OFLS is designed for operations that require high-availability for one-way transfers of critical data in operational environments. The failover capability allows customers to maintain operational dataflows whether there are planned (maintenance updates) or unplanned (communications disruptions) outages.
The OFLS application is installed on each of the Owl devices in the redundant pair. One of the devices is designated as the primary and the other is the secondary, creating an active/ passive failover pair. A communication link (heartbeat mechanism) is configured between the two devices on the destination side, allowing the devices to determine between themselves when a failure has occurred and when the secondary system should take over.
