Network Application User In ETSI M2M, there are no Human Users,

but only applications that process the data

coming from the ―Device and Gateway

Domain‖. This concept of an application as

a User is reflected in IoT-A.

Application

User In ETSI M2M, there are no Human Users,

but only applications that process the data

coming from the ―Device and Gateway

Domain‖. This concept of an application as

a User is reflected in IoT-A.

Service Service In ETSI M2M, Services are not defined as

exposing Resources on Devices, but can

interact with the Devices. A Resource

concept as in IoT-A does not exist.

Resource Service Resources in ETSI M2M are defined in

analogy to RESTful Service Interfaces.

Table 32 : Mapping ETSI M2M concepts to the IoT-A Domain Model.

As the current ETSI M2M release is rather concerned with data transport than
with real-world modelling, the (physical, virtual, augmented) entity concept is not
defined in [ETSI TS 103 092].

Mapping to the Management FG

Management functionalities are an inherent part of both of IoT-A and ETSI
M2M. Both architectures distribute and cluster the management functions into
different packages or functional components.

In [ETSI TS 102 690], the following packages are defined for management:

 General Management (GEN): Allows retrieving general information of the

M2M Device or gateway, and provides generic mechanism applicable to

different specific management functions;

 Configuration Management (CFG): Allows configuration of the device

capabilities and features for supporting M2M Services and applications,

including activating / deactivating device hardware components or I/Os in

the M2M Device or gateway;

 Diagnostic & Monitoring Management (D&M): Allows running specific

diagnostic tests on a device and collecting the results or alerts from the
