A system for load-testing a cloud radio access network (C-RAN) is provided. The system includes at least one radio point (RP), each being configured to exchange radio frequency (RF) signals with at least one user equipment (UE). The system also includes a baseband controller communicatively coupled to the at least one RP via a front-haul ETHERNET network. The front-haul ETHERNET network includes at least one switch; and a testing device that is time-synchronized to the baseband controller and the at least one RP. The testing device is configured to receive at least one packet from each of the at least one RP. The testing device is also configured to replicate each of at least some of the received packets to produce a respective replicated packet. The testing device is also configured to transmit at least one replicated packet to the baseband controller.
