                EdgeNative - Connector provides also a support for Edge Native Connector (3GPP TS 29.222: 3rd Generation Partnership Project; Technical Specification Group Core

                Network and Terminals; Common API Framework for 3GPP Northbound APIs).

              </p>

              <p>

                EdgeNative - Connector provides the user with two network simulation mechanisms to reproduce the behaviour of these 4G, 5G and Wi-Fi scenarios.

                The first mechanism is the built-in network characteristics emulation, which applies configurable latency, jitter, packet loss and throughput

                to the connectivity between terminals, points of access and MEC hosts, enabling rapid experimentation without an external radio stack.

                The second mechanism is an external radio network emulator based on Simu5G/SimuLTE, optionally coupled with SUMO/Veins for terminal mobility,

                so that user traffic and Radio Network Information (MEC012) can reflect a simulated radio access network rather than purely configured link parameters.

                In both cases, the ETSI MEC Service APIs remain the same, allowing the user to compare application behaviour under emulated and radio-simulated conditions.

              </p>

              <p>

                Such contextual information can offer significant differential performance for edge based MEC applications.

                EdgeNative - Connector also provides the support of capabilities described by Edge Platform Application Enablement (MEC011) and Device Application Interface (MEC016).
