Information technology. Telecommunications and information exchange between systems. Use of OSI applications over the internet transmission control protocol (TCP) Ingestion-build-109673 BS EN IEC 61051‑1:20181 Scope This International Standard defines a mechanism which allows OSI upper layers (all session, presentation, and application entities) to operate over the Internet Transmission Control Protocol (TCP) without being aware that they are running on a TCP IP internetwork. It provides similar functionality to ISO IEC Transport Protocol Class 4. It does not provide a gateway facility between Internet and OSI applications.
