Full title and description

ISO/IEC 21823-2:2020 — Internet of things (IoT) — Interoperability for IoT systems — Part 2: Transport interoperability. This international standard defines a framework, interfaces and requirements to achieve transport-level interoperability for IoT systems, enabling information exchange, peer-to-peer connectivity and seamless communication both between distinct IoT systems and among entities within a single IoT system.

Abstract

ISO/IEC 21823-2:2020 specifies transport interoperability interfaces and requirements to support the construction of interoperable IoT systems. It covers network connectivity models and the requirements for transport-layer connections both between separate IoT systems and inside an IoT system, with the goal of enabling reliable information exchange and peer-to-peer communication across heterogeneous deployments.

Scope

This document establishes requirements and interface definitions relating to transport interoperability for IoT systems. It addresses network connectivity models, the network stack and network interfaces required to support transport-level communication between different IoT systems and among elements within an IoT system. The standard is intended to assist designers and implementers in achieving interoperable, peer-to-peer information exchange at the transport layer across heterogeneous networks and devices.

Key topics and requirements

• Definition of transport interoperability concepts and reference connectivity models for IoT systems.
• Interfaces and requirements for transport connections between separate IoT systems (inter-system transport interfaces).
• Interfaces and requirements for transport connections within an IoT system (intra-system transport interfaces).
• Network stack considerations and recommendations for supporting seamless transport interoperability.
• Requirements to support reliable information exchange and peer-to-peer communication across heterogeneous network technologies.
• Guidance for implementers on how transport interfaces support higher-level interoperability facets (syntactic, semantic, behavioural, policy).

Typical use and users

Primary users are IoT solution architects, network and system engineers, device and gateway vendors, IoT platform developers, integrators and testing/verification teams. National standards bodies, conformity assessment organizations and researchers working on IoT interoperability or multi-vendor system integration also use this standard to align transport-layer designs and interoperability testing.

Related standards

ISO/IEC 21823-1 (Part 1: Framework) provides the overall interoperability framework. Other parts of the ISO/IEC 21823 series include Part 3 (semantic interoperability) and Part 4 (syntactic interoperability). Relevant supporting documents include ISO/IEC guidance and RFCs and specifications for underlying network and transport protocols used in IoT deployments. Implementers should consult the other parts of the 21823 series to cover syntactic, semantic, behavioural and policy interoperability facets.
