toodetel

Toodetel is a hypothetical data transport protocol introduced in educational materials to illustrate the design of low-latency messaging systems. It is described as a small, binary framing protocol intended for efficient transmission of short messages between distributed components. The design emphasizes minimal CPU overhead, predictable latency, and simple error handling.

The term itself does not refer to a real standard or widely deployed technology. It originated in online tutorials and classrooms as an example name to contrast with established protocols such as TCP, UDP, or more feature-rich messaging systems. As a result, implementations and specifications for toodetel are exemplar rather than normative, with variations existing across different teaching resources.

In typical descriptions, toodetel uses fixed-size or length-prefixed frames, lightweight header fields, and a simple reliability model that can be extended with optional acknowledgments and backpressure. It favors a stateless or semi-stateless approach to scalability, and often assumes a trusted network with occasional loss possible, handled by higher-layer logic.

Common educational applications include demonstrating framing, zero-copy data paths, message serialization, and the impact of backpressure on throughput. While there are no formal adopters or standards bodies for toodetel, the concept remains useful in pedagogy and in toy open-source projects that illustrate protocol design principles.
