TV CDS and VVI Topologies
Note When using ISVs, with the Vault and Streamer functions contained in one server, the only topology
possible is centralized.
Centralized Topology
In a centralized topology, all CDS servers are located in either a single video headend or a remote hub.
This is the right solution for certain situations, for instance very small starting systems or where a large
amount of bandwidth is available. A centralized topology has advantages in reducing operational cost
by placing equipment in one physical location. Figure 2-1 illustrates the centralized topology for Vaults
and Streamers.
