The challenges that are associated with the use of a passive optical network (PON) in mobile fronthaul, midhaul, or backhaul environments are significant. To address those types of challenges, techniques are presented herein that support radio aware transport, where radio Time Division Duplex (TDD) mode awareness is fed into a PON dynamic bandwidth allocation (DBA) algorithm. Additionally, a radio baseband processor (as a virtual network function (VNF) or a physical network function (PNF)) at a service layer may use a hardware slice of a PON’s optical line terminal (OLT) equipment for transport. Aspects of the techniques presented herein introduce more precise knowledge to a PON DBA to make it more intelligent, leverage developed information indicating when media is free from critical fronthaul traffic so that such unallocated time can be given to schedule other traffic types, protect and guarantee a service-level agreement (SLA) for very strict fronthaul traffic in terms of jitter, packet error rate, and latency, etc.
