Zixi Push Transmission Redundancy

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 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 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.    

Zixi push transmission redundancy can be deployed through the following configuration options:

• Single PUSH Transmission to Redundant Targets (Warm Redundancy)
• Single PUSH Transmission to Redundant Targets (Hot Redundancy)
• Dual PUSH Transmission to Single Target (Warm Redundancy)
• Dual PUSH Transmission to Single Target with High Priority Source (Warm Redundancy)
• Dual PUSH Transmission to Redundant Targets (Hot Redundancy)
• Dual PUSH Transmission to Redundant Targets (Full Cross Over)
