Toward end-to-end latency management of 5G network slicing and fronthaul traffic (Invited paper)

5G network slicing allows operators to deploy virtual connectivity services tailored for specific purposes on top of the same underlying physical infrastructure. For some services, telecommunication operator needs provide customer with real-time information end-to-end Quality Service a particular slice. This paper focuses challenges behind this target, how per-layer per-segment monitoring can be performed based common open interfaces standard OAM protocols, and provides practical rules plan latency slices. Then it reviews few engineering approaches fronthaul traffic from work carried out in research area.
