Summary

Recommendation ITU-T Y.4552/Y.2078 provides application support models of the Internet of things (IoT). This Recommendation describes the basis of IoT application support models: the configurable application support model, the adaptable application support model and the reliable application support model. These three application support models are described in functional view, implementation view and deployment view, in order to identify, respectively, the configurable capabilities, the adaptable capabilities and the reliable capabilities for support of IoT applications having some characteristic requirements.

This Recommendation describes the IoT configurable capabilities that extend the IoT basic capabilities specified in Recommendation ITU-T Y.4401/Y.2068 in order to enable the IoT applications to configure the IoT capabilities based on their characteristic requirements.

This Recommendation describes the IoT adaptable capabilities that extend the IoT basic capabilities specified in Recommendation ITU-T Y.4401/Y.2068 in order to enable the IoT applications to adapt to the IoT capabilities based on their characteristic requirements.

This Recommendation describes the IoT reliable capabilities that extend the IoT basic capabilities specified in Recommendation ITU-T Y.4401/Y.2068 in order to support the IoT applications by the IoT capabilities with required degrees of reliability for fulfilling their characteristic requirements.

Use cases from the smart home environment provide examples about the usage of the IoT application support models.
