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 .
