FOGCOMPUTING-OPENFOG

IEEE 1934 fog cloud-edge layer.

Definition

Fog Computing layers (IEEE 1934): Cloud (centralised, hours-days tolerable latency), Fog (regional, sub-second tolerable), Edge (device-local, sub-millisecond). OpenFog Reference Architecture published 2017. Differs from Edge Computing: Fog formalises intermediate layer between edge and cloud, Edge focused on device. IEEE 1934 published 2018 by IEEE Standards Association ; OpenFog Consortium absorbed by IIC (Industrial Internet Consortium) 2018, became OpenFog Working Group.

Origin

OpenFog Consortium founded November 2015 by Cisco, ARM, Dell, Intel, Microsoft, Princeton ; IEEE 1934 published 2018 ; absorbed by IIC 2018.

Example in context

A Barcelona smart city deploys 5000 edge pollution IoT sensors ; fog-level aggregation (district gateways) processes data, regional decision ; nightly sync to central cloud for analytics.
