DVB-CA Best Practices and Considerations

The following guidelines should be taken into consideration when setting up a DVB-CA system:
In a BNP redundancy configuration only the primary BNP is connected to the EIS, ECMG, and
•
EMMG servers.
During switchover the old primary (now standby) disconnects to CA servers and the new primary
•
reconnects to them.
The Update Timer is used to avoid sending clear streams during boot up & switchover because the
•
boot up time and CAS reconnection time vary from configuration to configuration.
It is recommended that Ethernet Port 2 be connected downstream of an IP switch such that
•
multicast traffic does not spill onto the CAS network and flood the EMM and ECM traffic.
The BNP can optionally be configured to receive EMM traffic via a multicast socket on Ethernet
•
Port 2.
Virtual IP configuration for Ethernet Port 2 must be configured when using 1:1 chassis redundancy;
•
this virtual IP address must be used by CA servers (external EIS and ECMG configuration).
