Topology Exposure & Inventory Overview

Topology Exposure & Inventory manages the representation of topology and inventory resources in a suite of evolving vendor-agnostic data models to share and operate on a common view of the topology.

Introducing Topology Exposure and Inventory data

Topology and inventory data is the information that represents entities in a telecommunications network and the relationships between them that provide insight into a particular aspect of the network of importance to specific use cases. Topology and inventory data can be derived from inventory, configuration, or other data. Topology & Inventory is being updated autonomously based on changes in the network.

Topology & Inventory supports several topology and inventory domains, The understanding of the model is important to enable a user making queries on topology and inventory data. The entities are modeled as managed objects and grouped together in modules based on functionality.
