MECPlatform

compound module

This module represents the MEC Platform entity within a MECHost, as specified in the ETSI MEC architecture (ETSI GS MEC 003). It encompasses the MEC services made available to MEC applications instantiated within the MEC Host, along with the ServiceRegistry. The type and number of available MEC services can be configured.

Used in compound modules

Name	Type	Description
MECHost	compound module	This module represents a model of a Multi-access Edge Computing (MEC) host belonging to a MEC system, as specified by the ETSI GS MEC 003 specifications. It runs MEC applications within its VirtualisationInfrastructure and can provide a number of MEC services via the MEC platform. MEC applications can be created either dynamically by the MEC orchestrator or statically at the initialization of the simulation. The MEC host possesses a configurable number of computing resources (such as CPU speed, RAM, and storage) and keeps track of the utilization of these resources by the MEC applications via the VirtualisationInfrastructureManager. Moreover, this module includes a User Plane Function (UPF) that allows it to be connected with the 5G core network.
