Dual PULL Transmission from Single Source (Warm Redundancy)

zixi can be deployed to pull a stream to redundant targets this topology shows a stream that is pulled from a single source node to a corresponding pair of redundant targets in a warm redundancy configuration the stream is not pulled in parallel, only when the main zixi receiver fails, the backup zixi receiver will be able to pull the stream from the zixi broadcaster a single input is created at the source zixi broadcaster, which includes a max outputs limitation of 1 output the same pull input is created in both the main zixi receiver and backup zixi receiver in runtime, the zixi receiver will connect to the zixi broadcaster and the output is created automatically "on the fly" if the main zixi receiver becomes unavailable, the zixi broadcaster will grant the backup receiver with the permission to pull the stream however, when the main zixi receiver becomes available again, zixi broadcaster will not grant a permission to pull the stream again (due to the max outputs limitation) until the backup zixi receiver stops pulling the stream source configuration to configure the source node (e g zixi broadcaster) on the inputs page of the primary zixi broadcaster, click new input on the upper right end corner of the screen in the stream id field, type a new name for the input stream select the a relevant connection type option in the max inputs field, type "1" specify the stream parameters according to the relevant connection type selected click ok to create the primary input target configuration a pull input should be configured in the primary and backup target nodes to configure the primary target node (e g zixi receiver) click the inputs tab at the top of the zixi receiver administrative screen click new input on the upper right hand side of the screen in the input name field, type a new name for the input select the pull option in the host field, enter the host name or ip of the primary broadcaster source in the port field, enter the connection port of the source host (primary zixi broadcaster) default 2077 in the stream field, enter the stream id used in the primary broadcaster source input configure additional parameters as required click ok to configure the secondary target node (e g zixi receiver) repeat the same configuration steps as the ones in the primary target node make sure you use the same input name used in the primary target node 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 latency considerations for detailed recovery time details, please contact your zixi representative
