In this example, the Netcrypt Bulk Encryptors may be physically located either in the
headend or at hubs along with their corresponding xDQAs. However, regardless of
their physical location and connectivity, through the specification and use of DNCS
GbE Transport Network Clouds, operators have a method for fine-grain control of
Netcrypt Bulk Encryptor bandwidth.
Using GbE "Splitter Transport Clouds" for Centralized and Distributed Network Bulk Encryptors
In a centralized/distributed architecture, it may be desirable to use both centralized
In a centralized/distributed architecture, it may be desirable to use both centralized
and distributed Netcrypt Bulk Encryptors. This may be accomplished using a
“splitter cloud” as shown in the example below.
In the example shown, the choice of Netcrypt Bulk Encryptor1 or Netcrypt Bulk
In the example shown, the choice of Netcrypt Bulk Encryptor1 or Netcrypt Bulk
Encryptor3 for streams bound for cloud1 is ambiguous. The DNCS will attempt to
balance the load between these Netcrypt Bulk Encryptors and also between Netcrypt
Bulk Encryptor3 and Netcrypt Bulk Encryptor2 for content bound for cloud2.
