Connectivity Framework Annex C: Assessment Template: oneM2M
C. 6.3 Usage Viewpoint
C. 6.3.1 Architecture( Section 6.3.1)
Summarize the main concepts, and high-level architecture, and terminology. Describe the end-to-end information exchange path.
oneM2M standards comprise a horizontal platform architecture that fits within a threelayer model comprising of applications, middleware services and networks.
Application Entities( AEs) are hosted on nodes( e. g., enterprise server, device). These nodes may be virtualized or physical instances. These AEs communicate with each other by sending requests to a Common Service Entity( CSE) that, in turn routes the request to the target AE while providing services based on the request.
C. 6.3.2 Technology Options
( Section 6.3.2)
CSEs are hosted on the nodes that may be virtualized or physical nodes. In many instances, the AE and CSE share the same node( e. g., device). List the choices to be made for using the connectivity technology in a system.
• Selection of the oneM2M Deployment: Applications interact with CSEs where the network of CSEs makes up the deployment architecture. The flexibility of placing the CSE on the end device, on the edge of a local network; in the cloud or somewhere in between( e. g., Fog) are all deployment options.
• Selection of network layer binding( s) for a CSE.
• Selection of interoperability gateways for a CSE.
