Scheduling in an Ethernet fronthaul network [PDF]

2017 European Conference on Networks and Communications (EuCNC), 2017
This paper investigates and compares the performance of different scheduling techniques in an Ethernet fronthaul network in the presence of both time-sensitive/high priority and background traffic streams. A switched Ethernet architecture is used as the fronthaul section of a cloud radio access network (C-RAN) and a comparison of two scheduling schemes,
