Using GbE Transport Clouds to Specify Any-to-Any Connectivity
Any-to-any connectivity would be specified by creating one GbE transport cloud
Any-to-any connectivity would be specified by creating one GbE transport cloud
and connecting every port of every Netcrypt Bulk Encryptor and QAM modulator to
that cloud, as shown in the first example below.
Each port of a Netcrypt Bulk
Encryptor must be connected to
ports on one or more GbE
Transport clouds.
Each GbE Transport cloud
may have an arbitrary
number of ports.
Each QAM (session-based or
table-based) that is reachable from
a GbE Transport cloud must also
be connected to a port on one or
more clouds.
Using GbE Transport Clouds to Control and Manage Network Connectivity
In a physical network implementation, any QAM may be reachable from a particular
In a physical network implementation, any QAM may be reachable from a particular
Netcrypt Bulk Encryptor. Nevertheless, limiting a Netcrypt Bulk Encryptor to a
subset of QAMs through the use of GbE transport clouds may be useful for load-
balancing, traceability, or other reasons. This is illustrated in the example below.
Here, the DNCS will only use Netcrypt Bulk Encryptor1 for streams bound for
XDQA1 or XDQA2. Similarly, Netcrypt Bulk Encryptor2 will only be used for
streams bound for XDQA3 or XDQA4.
