e240ri

e240ri is a fictional open standard developed for low-latency real-time data exchange between sensors and edge processing units. Named to evoke a 240-unit data rate and real-time (ri) communication, it is designed for modularity and interoperability across hardware platforms.

Origin and development: The concept emerged in speculative technical writing and has since been used in demonstrations of protocol design. In the fictional project, the standard was designed to be transport-agnostic, able to run over Ethernet, USB, or custom links.

Technical overview: The protocol defines a compact frame with a fixed-size header carrying version, payload type, timestamp, and sequence number, followed by a variable-length payload. It supports multiple transport bindings and optional security, including lightweight encryption. A reference implementation emphasizes portability and minimal CPU overhead.

Applications: In the fictional ecosystem, e240ri is used for sensor fusion in autonomous systems, industrial automation labs, and embedded education kits. Its modular design allows researchers to swap transport layers without changing the core data model.

Reception and outlook: As a hypothetical standard, e240ri has not been adopted in real-world deployments. It is mainly used in instructional contexts to illustrate design trade-offs in real-time communication protocols, and it continues as a case study in protocol engineering.
