It is possible to more tightly control the use of Netcrypt Bulk Encryptors by
connecting sources to the GbE Transport Networks as shown in the example below.
In this case, the GbE port IP addresses of the VOD pumps are entered into the DNCS
when connecting pump ports to GbE Transport Network ports.
In this case, the DNCS will use Netcrypt Bulk Encryptor 3 only for streams coming
In this case, the DNCS will use Netcrypt Bulk Encryptor 3 only for streams coming
from VODSource3. Similarly it will use Netcrypt Bulk Encryptor1 for streams
coming from VODSource1 and so on.
The problem with this method is that not all VOD servers specify their selected
The problem with this method is that not all VOD servers specify their selected
source ports to the DNCS when a VOD session is set up. If a VOD server fails to
specify the source IP address for a stream, the ambiguity will not be resolved and the
DNCS will respond to the VOD server with the IP address of any Netcrypt Bulk
Encryptor it chooses given the connectivity that has been specified.
