A Zixi PULL input can be configured with multiple, ordered, failover sources. The topology includes a target node pulling from a primary source. In the event that the primary source becomes unavailable, the target node will automatically switch to the secondary source. The target node will attempt to pull the primary sources again only in the event that the secondary source becomes unavailable. 

Source Configuration

To configure the primary source node (e.g. Primary Zixi Broadcaster):

1. On the Outputs page of the primary Zixi Broadcaster, click New Output on the upper- right end corner of the screen.
2. In the Output Name field, type a new name for the output. 
3. In the Input Stream field, select the relevant input stream.
4. Select the Pull option.
5. In the Output Parameters section, in the StreamID field, enter an ID string for the stream. This ID should match the ID used in the Input. 
6. In the Remote ID field, enter the Receiver ID that will pull stream. The Receiver ID can be found in the Status page of the Zixi Receiver (http://localhost:4300) under the Receiver Status section.  
7. In the Latency field, set a desired buffer size that ZiXi Broadcaster will maintain for error correction. 'Remote configuration' uses the latency configured in the Receiver.   
8. Click OK to create the primary output.

To configure the secondary source node (e.g. Secondary Zixi Broadcaster):

1. Repeat the steps used to configure the primary Zixi Broadcaster. Make sure to use the same Stream ID and Remote ID. 

2. Click OK.

Target Configuration

To configure the target node (e.g. Zixi Receiver):

1. Click the Inputs tab at the top of the Zixi Receiver administrative screen
2. Click New Input on the upper right hand side of the screen.
3. In the Input Name field, type a new name for the input. 
4. Select the Pull option.
5. Create an input at the primary target, ensuring the “Stream ID” matches that of the primary and secondary sources output.In the Host field, enter the host name or IP of the primary source. 
6. In the Backup Host field, enter the host name or IP of the secondary source.
7. In the Port field, enter the connection port of the host (Zixi Receiver). Default: 2077. 
8. In the Stream field, enter the stream ID used in the primary and secondary source outputs. 
9. Configure additional parameters as required. 
10. Click OK.

Cost Considerations

This topology duplicates the source Zixi hardware and software components. It does not require doubling the uplink bandwidth as the backup connection stream is only active in the event that the primary fails.
