Single PUSH Transmission to Redundant Targets (Hot Redundancy)

a zixi source can be configured to push a single input stream to multiple output targets in parallel the topology includes a source node receiving a single ip input, while simultaneously pushing the stream to two live targets two differently named outputs are created at the source using the same input stream if the latency of the outputs is identical, the streams will be frame synced, provided that the video is synced during its entry source configuration the following procedure describes how to configure the zec to push a single stream to two target hosts in a hot redundancy configuration in order to configure a hot redundancy you will need to create two outputs containing the same stream id with the same latency configuration the procedure does cover instructions on how to configure the input into the zixi feeder to configure the first source output in the source node (e g zec) on the outputs page of zixi feeder, click the new output button, located in the upper right end corner of the screen in the output name field, type a new name for the output in the type field, select push radio button in the input stream field, select the relevant input stream in the program field, if you have created a filter for the stream, select the relevant program in the stream id field, enter a stream id (alphanumeric) the same stream id will be also configured in the target nodes (push input) optional in the password field, specify a string to be used at the destination to authenticate that the pushing broadcaster is allowed to push this stream in the max latency field, specify the buffer size that zixi broadcaster will keep for error correction for example, 6000 milliseconds would ensure that the stream is protected for six seconds of errors in the network default 6000 in the host field, enter the host name or ip of the primary target in the port field, specify the destination port to listen on for the push stream (default 2088) in the local ip field, select from the drop down menu, the ip address of the nic (network interface card) in the source through which the stream will be pushed click ok the output is added to the outputs list to configure the second source output in the source node (e g zec) repeat the same instructions the second output is added to the outputs list target configuration the following procedures describe how to configure the two target zixi broadcasters in a hot redundancy configuration the two targets use different stream ids, as configured in the first and second sources to configure the first target node (e g zixi broadcaster) click the inputs tab at the top of the first zixi broadcaster administrative screen click new input on the upper right hand side of the screen in the stream id field, enter the same “stream id” as the first source output select the push radio button option in the password field, if you have configured a password in the source (feeder output), enter the same password configure additional parameters as required click ok to configure the second target node (e g zixi broadcaster) repeat the same instructions the second input is added to the inputs list cost considerations this topology duplicates the target side zixi node software and hardware components this configuration also requires doubling the up link bandwidth it is recommended to allocate more than twice the expected maximum bit rate to ensure head room latency considerations for detailed recovery time details, please contact your zixi representative
