This paper compares the performance of traditional priority-based queuing regimes with a time-aware shaping scheduler in an Ethernet fronthaul. Different use-cases are considered for the high and low priority traffic generation, which are made to represent precision-time protocol traffic and traffic originating from different LTE functional subdivisions (function splits) respectively. It is shown that that the relative performance characteristics of the three scheduling regimes depend strongly on the utilization of the fronthaul links where contention is taking place and on the traffic generation characteristics of the different traffic sources.
