MEC is a network architecture concept that enables Integrated networking, computing and storage resources into one programmable and unified edge infrastructure.

Mobile/Multi-access Edge Computing (MEC)

The basic idea behind MEC is that by running applications and performing related processing tasks closer to the cellular customer, network congestion is reduced and applications perform better.

The MEC infrastructure resides at the edge of the operator infrastructure.

The operator own and manages the infrastructure but not the “things”

The Fog infrastructure resides on premises and at the edge of end-system infrastructure.

The fog infrastructure as well as the “things” are often owned and managed by the same authority, i.e. smart factory, smart grid, etc.

The ability of leveraging Fog, on premises, and MEC at the edge of the network, will be the ideal situation for demanding IIoT applications

MECFOG

From an high level perspective MEC and Fog computing aim

at virtualising compute, storage and networking at the

edge

Yet, their requirements differ significantly in some areas as Fog computing deals with OT

systems

MEC / Fog Needs

Summing UPMEC and Fog Computing aims at the same high level goal, which is providing a virtualised compute, storage and communication fabric

Yet they have unique requirements stemming from the target application domain

Platform that wish to address and unify MEC and Fog computing need to exploit similarities but more importantly address the differences
