My Bachelor’s thesis is about Time-Sensitive Networking (TSN). TSN is a standard developed by the IEEE to extend Ethernet by guaranteeing upper bounds for latency and jitter. This time-sensitivity can only be enabled by precise and synchronized clocks on all network devices. Hence, my thesis tries to explore the impact of naturally occurring clock imprecision on TSN by first looking at optimal networking conditions solely replicable in a simulation environment. Then later I make use of countermeasures like bigger transmission time windows or clock synchronization provided by gPTP and evaluate them with common metrics like latency, jitter and packet queue length.
At the end my thesis provides the reader an overview of the different countermeasures’ viability in the real world. Clock synchronization does perform better than all other variants tested and is invaluable in assuring stable transmissions.
