Topology data
When the network is discovered, both core NCIM tables and entity attribute tables are updated with topology data. These tables include Layer 1, Layer 2, Layer 3, device structure, routing protocol, containment, and technology-specific information.
The NCIM tables are not case-sensitive.
The core and entity attribute tables are listed in the data dictionary.
Data modeled by NCIM
NCIM models different types of network data, including the following:- IP networks
- NCIM models network devices and device connections within layer 2 and layer 3 of the OSI model.
- Optical networks
- NCIM models optical network devices within layer 1 of the OSI model.
- Routing networks
- NCIM models routing networks based on routing protocols such as MPLS, BGP, and OSPF.
- VLANs
- NCIM models Virtual Local Area Networks (VLANs).
- Radio access networks
- NCIM models a variety of radio access networks (RANs), including GSM, UMTS, and LTE.
