The source code for this example is released with your software in the following locations:
- C source code:
- DDL source:
The IPTV Monitor sample application monitors selected Real-time Transfer Protocol (RTP) streams and calculates their media delivery index (MDI) (RFC 4445). The application is designed to be deployed on any nodes that pass IPTV broadcast service or video on demand (VoD) streams which are respectively delivered over IP Multicast and Unicast. (This topic assumes the reader has basic knowledge of IPTV and MDI.)
- ODL source:
The application is supported on Juniper M- and T-series routers with Multiservices PICs.
The user can enter either of two commands to display the monitoring statistics:
show sync monitube statistics shows the MDI values for all monitored flows. Values from the PIC can come as often as every second. By default, this command shows the latest values received from the PIC; however, if the results are more than 5 minutes old, the application clears them automatically.
Either command can take one optional parameter, the group name from the
clear sync monitube statistics clears the statistics on demand.
monitored-networks group defined in the configuration. Specifying this parameter causes the application to show or clear only the statistics for flows falling into that group. Omitting it displays or clears the results for all configured groups.
