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 zecs 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 zec to configure the primary source node (e g zec) on the outputs page of zec, 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 option in the input stream field select the relevant the input stream 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 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 zec) repeat the steps above 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 zec before you begin, you must obtain the id of the zec that will be used as the high priority source to obtain the high priority zec id go to the status page of the primary zec the zec 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 time details, please contact your zixi representative
