    To ensure that 5G network's strict requirements are met in the fronthaul, the eCPRI Transport Network requirement document establishes classes of service for data and C&M traffic. With full line rate eCPRI traffic generation capabilities and high accuracy one-way latency measurements, the eCPRI test application provides the tools necessary to ensure that the eCPRI transport network is ready for 5G deployments.
