Connected Home Data Models

The selected resource is relevant to both CWMP and USP Data Models.

Broadband Forum defines several data models that describe the service elements (objects, parameters, commands, and events) of broadband CPE, consumer electronics, “smart” devices/IoT, and both home and business network equipment, including Wi-Fi deployments.

  • USP Data Model – USP (TR-369) is a standardized protocol to manage, monitor, update, and control connected devices. services and home networks
  • CWMP Data Model – CWMP (TR-069) is the industry standard CPE WAN Management Protocol

Each data model is defined by a Name:Version syntax, and are divided into two types: Root and Service. The root data model, Device:2 is used to describe the major functions of a network aware device, including interfaces, software/firmware, diagnostics, components common to USP/CWMP, and the basic information necessary to the function of these protocols. The Device:2 data model is published as Broadband Forum Technical Report 181, or TR-181 Issue 2 and is often referenced this way.

Service data models describe modular functionality that allow the extension of the root data model on a device (under Device Services) to provide particular services, such as a voice service, set top box service, network attached storage, IoT objects, etc.
