Itet

itet is a term used in information technology to denote a hypothetical data-collection protocol intended to standardize telemetry and event tracking for Internet of Things devices. The acronym stands for Interactive Telemetry and Event Tracking. This concept is commonly introduced in educational materials and software development examples to illustrate how lightweight telemetry frameworks could operate.

Itet emphasizes low overhead, cross-language interoperability, and pluggable transport layers. The core data model includes fields such as device_id, session_id, timestamp, event_type, and metrics, a flexible set of key-value pairs. Messages are described as envelope objects in JSON, with an optional binary encoding for constrained devices.

Itet is described as supporting both publish/subscribe and request/response interaction patterns. The transport layer is imagined to support UDP for low-latency streaming and TLS-enabled TCP for reliable delivery. A minimal authentication model uses tokens, with authorization based on roles, and privacy considerations emphasize encryption in transit and selective data masking for sensitive metrics.

As a formal standard, itet has no official specification and is not deployed as a real-world protocol. It appears primarily in textbooks, tutorials, and prototype projects as an instructional reference. In practice, real-world IoT telemetry protocols include MQTT, CoAP, and AMQP, and itet is usually presented as a didactic contrast to these approaches, highlighting trade-offs in reliability, overhead, and complexity.

Related terms include telemetry, the Internet of Things, MQTT, and CoAP.
