scope:

This Recommendation describes basis of application support models of the Internet of things (IoT) and specifies three application support models of the IoT: the configurable application support model, the adaptable application support model and the reliable application support model.

The three application support models are specified in functional view, implementation view and deployment view respectively.

The configurable capabilities, adaptable capabilities and reliable capabilities related, respectively, to each of the three models, are also identified and described. The scope of this Recommendation includes:

− The basis of application support models;

− The functional view, the implementation view and the deployment view of the configurable application support model and related configurable capabilities that extend the IoT basic capabilities specified in [ITU-T Y.4401] to enable the IoT applications to configure the IoT capabilities based on their characteristic requirements;

− The functional view, the implementation view and the deployment view of the adaptable application support model and related adaptable capabilities that extend the IoT basic capabilities specified in [ITU-T Y.4401] to enable the IoT applications to adapt to the IoT capabilities based on their characteristic requirements;

− The functional view, the implementation view and the deployment view of the reliable application support model and related reliable capabilities that extend the IoT basic capabilities specified in [ITU-T Y.4401] to support the IoT applications by the IoT capabilities with required degrees of reliability for fulfilling their characteristic requirements.

All capabilities identified and specified in this Recommendation are numbered and summarized in the annexes.

Appendix I shows three use cases of the IoT application support models from the smart home environment.

NOTE - Only three IoT application support models are described and specified in this Recommendation. The specification of other application support models is outside the scope of this Recommendation and for further consideration.
