level as well as between the factory-floor and the enterprise IT cloud. There are explorations of use outside of manufacturing, although no deployed implementations.

7.1.4 ONEM2M
oneM2M is a relatively new standard( 2015) managed by a partnership of regional international standards industry organizations in the telecommunications industry.
oneM2M provides a common service layer that sits between applications and connectivity transport. It offers functions that IoT applications across different industry segments commonly need. Those functions are exposed to applications via RESTful APIs.
oneM2M standards comprise a horizontal platform architecture that fits within a three-layer model comprising of applications, middleware services and networks. oneM2M ' s connectivity standards permit applications that are hosted on connected machines and devices, enterprise systems and mobile devices to communicate with each other in an efficient, secure manner. The oneM2M horizontal platform is scalable as the common service elements are able to be deployed on hosts, at the proximal network edge or within the enterprise cloud.
Connectivity services provide capabilities that allow for efficient communication between application endpoints. It provides interworking mechanisms that adjust the underlying network( e. g., mobile, wireless) quality of service to meet the needs of current application data exchange. Currently, the oneM2M service layer can use HTTP, CoAP, MQTT and WebSockets for connectivity transports. DDS is being explored as another option for providing real-time connectivity between the oneM2M service layer entities. Also, an interworking gateway between oneM2M and DDS and OPC-UA is under investigation.
Typical usage of oneM2M includes registration and subscription of devices and applications, service charging and accounting, management of application and devices, and monitoring.
oneM2M has commercial deployments in home-automation applications. It is suitable for largescale consumer IoT applications. oneM2M is also actively engaged in deployments in other IIoT application domains, including telematics and intelligent transportation, home automation, utilities, healthcare, smart cities, and industrial automation. In all these domains, oneM2M provides semantic enablers( in the scope of the Distributed Data Interoperability and Management layer). As a key part of the telecommunication industry’ s existing initiatives and its new“ 5G” initiative, oneM2M provides enablers that focus on the connection between device and the cellular network.
To date, the real-time data distribution performance, latency, jitter benchmarks of oneM2M deployments have not been documented and made publicly available.
