Dual PULL Transmission from Single Source (Hot 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 hot redundancy configuration the stream is pulled in parallel by the two redundant targets, creating two redundant paths to the destination two distinctly named outputs are created at the source zixi broadcaster each output is configured to stream to one of the redundant zixi receivers if the latency of the outputs is identical, the streams will be frame synced, provided that the video is synced on entry a single input is created at the source zixi broadcaster this input may include unlimited max outputs, which will enable multiple simultaneous pull connections if you want to limit the number of pull connections, you can enter the desired number of max outputs (e g enter '2', if you have two zixi receivers pulling) in runtime, the two zixi receivers will connect to the zixi broadcaster and the two outputs are created automatically "on the fly" additional connections will be denied alternatively, you can manually configure the two pull outputs in the zixi broadcaster 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, do one of the following leave it as unlimited specify the maximal number of connections (e g type "2" to enable two pull connections) 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 target zixi hardware and software components the configuration also requires using double the up link bandwidth allocation of twice the expected maximum bit rate with head room is advised latency considerations for detailed recovery time details, please contact your zixi representative
