BroadBand Forum Data Models (BBFDM)
bbfdm is a datamodel backend for Higher layer management protocols like TR-069/CWMP or TR-369/USP. It is designed in a hardware agnostic way and provides the available datamodel parameters over ubus on the northbound interface and creates the datamodel mapping based on uci and ubus on southbound interface.
bbfdm has three main components:
| Component | Description |
|---|---|
| bbfdmd | A daemon to expose data model objects over ubus in pretty and raw format |
| libbbfdm-api | A shared library which provides API to build and parse datamodel tree, it also provides API to create datamodel extensions using shared DotSo plugin, or with JSON Plugin. |
| libbbfdm | A datamodel tree/library build with libbbfdm-api, it includes core TR181 and related datamodel |
