BroadBand Forum Data Models (BBFDM)

bbfdm is an implementation developed by iopsys that conforms to Broadband Forum Data Models and which includes a list objects, parameters, events and operates used for CPE management through remote control protocols such as TR-069/CWMP or TR-369/USP.

This implementation comprises of the three main components:

Component	Description
libbbfdm-api	It is a library that provides many APIs used to interact with UCI configurations, Ubus objects, JSON schema, CLI commands and memory management. It also provides a mechanism to add new objects, parameters, events and operates or extend the existing DM tree using json plugin or shared library plugin.
libbbfdm	It's a libarry that provides the different data models supported by iopsys
bbfdmd	It's a deamon which used to expose data model objects over ubus

Design of bbfdm

bbfdm package is structred as follow:

├── bbfdmd
├── docs
├── libbbfdm-api
├── libbbfdm
│   ├── dmtree
│   │   ├── json
│   │   ├── tr104
│   │   ├── tr143
│   │   ├── tr181
│   │   ├── tr471
│   │   ├── vendor
│   ├── scripts
└── tools

• bbfdmd folder which contains the source code of bbfdm deamon. More explanation on how this daemon works and all supported methods are presented in this file BBFDMD

• libbbfdm folder which contains the different data models supported by iopsys

  • dmtree folder which includes all supported Data Models and vendor extension objects. It contains 6 folders:

    • tr181 folder : TR-181 Data Model files

    • tr104 folder : Voice Services Data Model files

    • tr143 folder : Diagnostics Data Model files

    • tr471 folder : IPLayerCapacityMetrics Diagnostics Data Model files

    • vendor folder : Vendor Data Model files

    • json folder : TR-181 and TR-104 JSON files

  • scripts folder which contains all the scripts used to run the different types of diagnostics.

• libbbfdm-api folder which contains the source code of all API functions (UCI, Ubus, JSON, CLI and memory management). These API are used for GET/SET/ADD/Delete/Operate calls which can be called in internal or external packages. All APIs exposed by libbbfdm-api are presented in this header file libbbfdm_api.h.

• tools folder which contains some tools to generate Data Model in C, JSON, XML and Excel format. All supported tools are presented in this fileBBFDM Tools

• docs folder which contains all documentation files.
