ITU-T Y.4122 PDF

Compared with the common gateway [ITU-T Y.4101], the edge-computing-enabled gateway in the Internet of things (IoT) – abbreviated as the EC-enabled IoT gateway – has additional capabilities supporting service layer interworking and application layer interworking between IoT devices, IoT platforms and IoT application servers. In addition, the EC-enabled IoT gateway supports data transmission capabilities for IoT applications sensitive to time, latency, jitter and packet loss.

Based on common requirements and capabilities of a gateway for IoT applications [ITU-T Y.4101] and IoT requirements for support of edge computing [ITU-T Y.4208], additional capabilities and a capability framework of the edge-computing-enabled gateway in the IoT are specified.

The scope of this Recommendation includes:

– The introduction of the EC-enabled IoT gateway;

– The requirements of the EC-enabled IoT gateway;

– The capabilities of the EC-enabled IoT gateway;

– The capability framework of the EC-enabled IoT gateway.

The appendix provides examples of applicability of the EC-enabled IoT gateway.

NOTE – Direct communication of the EC-enabled gateway with other gateways in the IoT is out of scope of this Recommendation.
