Topology storage architecture

Use this information to understand how the NCIM database interacts with other components of Network Manager.

The following figure shows how data flows through the NCIM database.

Figure 1. Topology storage data flow
Topology storage dataflow
 1  Topology is transferred from the Topology manager, ncp_model
Following a discovery, the Topology manager, ncp_model, sends the topology to the Network Connectivity and Inventory (NCIM) database.
 2  Network administrators query the NCIM database
Network administrators query the NCIM database using SQL queries to retrieve detailed topology data.
 3  Topology visualization web applications access the topology
The topology visualization web applications, running within Dashboard Application Services Hub, access the topology. This enables the topology visualization GUIs, Hop View, Network Views, and Structure Browser, to display network topology and device structure.
