IFN 712 - MQTT over KCP prototype program

A prototype program for PoC (Proof of Concept), is used to check and compare the latency performance between MQTT over TCP and MQTT over KCP.

DO NOT USE THE PROJECT IN PRODUCTION ENVIRONMENT!

Loading

The program will record all test records into a .xlsx file for analysis purposes.

Environment for Experiment1

The experiment needs to be performed in different environments/configurations
