28.1 TR-369 Overview
TR-369 or USP (User Services Platform) is a standardized protocol for managing, monitoring, upgrading,
and controlling connected network devices. It can manage WiFi, mesh networks, or IoT devices in smart
homes. The TR-369 agent collects and analyzes data from network devices to identify potential
problems and generate reports and alerts and sends them to a controller.
A service element refers to the set of objects, commands, events, and parameters that represent a
specific set of functionality that can be modified by a controller on an agent. An agent, the Zyxel
Device, ZD in the following example figure, exposes service elements to one or more controllers (CA, CB,
CC in the example figure below). A controller manipulates service elements through one or more
agents. The Instantiated Data Model (IDM) of an agent represents the current status of service elements
that are exposed to one or more controllers. The Supported Data Model (SDM) of an agent represents
the complete set of service elements it is capable of exposing to a controller.
A message refers to the contents of a TR-369 communication. A Message Transfer Protocol (MTP) is the
protocol that carries a message. The endpoint must be identified by a locally or globally unique
endpoint identifier depending on the scheme used for assignment.
