A system includes a plurality of remote units; a centralized unit communicatively coupled to the plurality of remote units via a fronthaul network; and an entity that performs deep packet inspection. The centralized unit transmits sets of data to the plurality of remote units across the fronthaul network in packets, each of the sets of data mapped to at least one of the plurality of remote units and each of the packets including a respective indicator indicating each remote unit the associated packet is intended for, wherein each indicator comprises a plurality of bit positions where each bit position is mapped to a different one of the plurality of remote units. The entity performs the deep packet inspection on the packets to determine each remote unit the packets are intended for and communicate each packet to each remote unit the packet is intended for over the fronthaul network.
