ISO IEC TR 30164:2020 pdf free.Internet of things (IoT) – Edge computing
Edge computing is a form of distributed computing in which processing and storage takes place on a set of networked machines which are near the edge, where the nearness is defined by the system’s requirements. The edge is marked by the boundary between pertinent digital and physical entities (i.e. between the digital system and the physical world) typically delineated by loT devices and end-user devices. Nearness is determined by the system requirements, which can include physical distance, but can also include digital factors such as network latency and bandwidth.
Pertinent digital entities here means that the digital entities which need to be considered can vary depending on the system under consideration and the context in which those entities are used.
Digital systems can observe and affect the physical world. Sensors, actuators and human user interface devices are at the boundary between the physical world and digital systems (the edge).
Edge computing systems generally combine these devices with distributed computing resources to provide the capabilities of the system. When actions need to occur within specific timeframes and latency considerations affect system design, the edge computing systems help to achieve timing requirements by means of appropriate placement of data processing and data storage.
The following are the main motivations for edge computing.
a) Latency: actions often need to occur within specific timeframes and latency considerations affect system design and the choice of the placement of data processing and data storage to achieve timing requirements.
b) Disconnected operations: for example, a car in a canyon. AlI essential functions need to continue to work.
c) Paucity or high cost of the uplink: for example, an oil rig, a cruise ship or an airliner connected via a satellite link. Need to minimize the volume of data transmitted upstream.
d) Data providence: for example, data represents trade secrets and should not leave a geofence (factory space or corporate network).ISO IEC TR 30164 pdf download.
