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,

Transport Network Design for FrontHaul [PDF]
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017 The evolution of LTE and advent of 5G networks increases further the bandwidth requirements for RAN. In parallel, the deployment of Centralized RAN architecture raises new challenges on the FrontHaul network. The inflexibility of the legacy CPRI is the primary challenge to Virtualized RAN deployments, and there is currently a strong trend towards the ...
