A Simulation Model of IEEE 802.1AS gPTP for Clock Synchronization in OMNeT++

Abstract

The aim of this paper is to describe a developed simulation model of the gPTP protocol for time synchronization in OMNeT++ using the INET library. gPTP is part of the IEEE TSN standards. Unfortunately, there is currently no simulation model of gPTP available. Therefore, we developed a new simulation model, compared it to results from the state-ofthe-art, and would like to share it with the OMNeT++ community. The simulation model is based on the IEEE 802.1AS specification for full-duplex Ethernet according to a given network topology and use case scenario to analyze the results of the simulation as well as to provide a comparison with results from the state-of-the-art. Time synchronization and propagation delay measurements between time-aware systems are considered and results show that the simulation model works as expected.
