Overview
ISO/IEC 30161-2:2023 defines transport interoperability requirements for nodal points in an Internet of Things Data Exchange Platform (IoT DEP). Building on ISO/IEC 30161-1:2020 (general IoT DEP architecture), this part focuses on how multiple nodal points cooperate to exchange IoT data efficiently across wide geographic or large-scale deployments. It specifies requirements, functional blocks, and operation mechanisms to enable low-overhead, low-latency data transfer among nodal points in an IoT DEP network.
Key topics and technical requirements
- Scope: Transport interoperability between nodal points in an IoT DEP network - including requirements, functional blocks, and operation mechanisms.
- Nodal point role: Nodal points (e.g., gateways) perform routing and forwarding of IoT data blocks; endpoints (devices, users) connect to nodal points.
- Functional sub-blocks defined in the standard:
- Interworking (routing and forwarding functions)
- Interoperability management
- Interoperability control
- Operation mechanisms to support different transfer patterns:
- Request-based transfer (static assignment and dynamic discovery)
- Data-based transfer (static assignment and dynamic discovery)
- System parameters & data types: Defines parameters and classifications for IoT data exchange and transfer types to meet QoS and performance needs.
- Transport-layer agnostic: Transport interoperability among nodal points is achieved at the IoT DEP middleware level and is not constrained by specific transport-layer protocols (OSI layer separation).
- Latency considerations: Informative annexes address latency-critical IoT services and storage strategies for nodal points to support time-sensitive use cases.
Practical applications
- Enabling multi-vendor interoperability across IoT gateways and platforms in large-scale, distributed IoT systems.
- Facilitating low-latency data acquisition (industrial monitoring, real-time analytics) by optimizing routing/forwarding among nodal points.
- Supporting cross-domain IoT data exchange where endpoints and services are distributed across different networks and geographical regions.
- Standardizing middleware behavior for IoT platform developers, gateway vendors, cloud integrators, and system architects to reduce integration overhead.
Who should use this standard
- IoT system architects and solution designers planning scalable IoT DEP networks.
- Gateway and middleware vendors implementing nodal point functionality (routing, forwarding, management).
- Network integrators and operators deploying geographically distributed IoT services.
- Standards and compliance teams assessing interoperability and QoS for IoT deployments.
