Dual PUSH Transmission to Single Target with High Priority Source (Warm Redundancy)

a zixi push input can be configured to switch to a designated hi priority source the topology includes redundant source nodes pushing to a primary target in this configuration the sources do not contend for the target input if the high priority source connection is available it will take over the input in the event the connection is lost, the secondary stream will assume the connection however, if the primary connection returns, the target will drop the secondary connection and return to the primary stream source configuration the following procedure describes how to configure two zixi feeders to push a single stream to a target hosts in a warm redundancy configuration the procedure does not cover instructions on how to configure the input into the zixi feeder to configure the primary source node (e g zixi feeder) on the outputs page of zixi feeder, click the new output button, located in the upper right end corner of the screen in the name field, type a new name for the output in the type field select push to broadcaster in the input name field select the relevant the 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 node (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 bitrate field, specify the maximum bitrate of the stream default 8000 this is used for internal memory allocation and will not affect the transmitted bitrate recommended double the bitrate of the 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 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 secondary source node (e g zixi feeder) on the outputs page of zixi feeder, click the new output button, located in the upper right end corner of the screen in the name field, type a new name for the output this name does not have to be the same as the one used in the primary source node in the type field, select push to broadcaster in the input name field, select the same input stream as the one used in the primary source node 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) this should be the same stream id that was defined in the primary source node 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 bitrate field, specify the maximum bitrate of the stream default 8000 this is used for internal memory allocation and will not affect the transmitted bitrate recommended double the bitrate of the 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 ensure its the same max latency that was used in the primary source node in the host field, enter the host name or ip of the primary target (the same as the one configured in the primary source) in the port field, specify the destination port to listen on for the push stream (default 2088) in the 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 in the secondary source target configuration the following procedures describe how to configure the target zixi broadcaster in a warm redundancy with high priority source configuration the target is configured with a single input if this input is unavailable the secondary input will be received the input must use the same stream id that was used to configure the primary and secondary source zixi feeders before you begin, you must obtain the id of the zixi feeder that will be used as the high priority source to obtain the high priority zixi feeder id go to the status page of the primary zixi feeder the zixi feeder id is presented in the id field under program information to configure the target node (e g zixi broadcaster) click the inputs tab at the top of the secondary 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 source outputs (matches that of the primary and secondary sources output) select the push option under stream parameter, in the id of high priority source field, enter the high priority zixi feeder id configure additional parameters as required click ok cost considerations this topology duplicates the source side zixi node software and hardware components it does not require doubling the up link bandwidth, as the backup connection stream is only active in the event that the primary stream fails latency considerations for detailed recovery
