12. Application & Device Management

GEISA provides a uniform mechanism for managing edge devices and the applications that run on top of them. ADM conformant devices from different platform vendors can be managed by a single ADM conformant edge management system. See System Architecture for more discussion of the general concept.

ADM conformance devices support a set of standard transactions using the Open Mobile Alliance Lightweight M2M [LWM2M] transaction definitions, over the IETF CoAP [RFC7252] protocol. ADM conformant platform implementations MUST support the LWM2M transactions detailed in this chapter and the supporting device behaviors described. ADM conformant edge management systems MUST support the LWM2M transactions detailed in this chapter and the supporting edge management system behaviors described.

Note

ADM conformance does not preclude platforms or edge management systems from supporting additional or supplementary management protocols.

Note

Platform vendors may offer an ADM conformant device without offering an ADM conformant edge management system or an ADM conformant edge management system without offering an ADM conformant device.

As described in the GEISA Application Programming Interface (API), GEISA provides a default Application Messaging and Configuration mechanism. ADM conformant platforms transport these messages over CoAP. ADM conformant edge management systems expose these messages over a local ReST API, allowing other systems to easily consume messages sent by edge applications or to send messages to edge applications.
