Abstract:
A C-RAN includes a plurality of remote units (RUs), each being configured to exchange RF signals with at least one UE. The C-RAN also includes a central unit communicatively coupled to the plurality of RUs via a fronthaul interface. The fronthaul interface includes at least one ETHERNET switch configured to perform deep packet inspection on a received packet in order to determine whether an RU identification is present in the packet. The RU identification, if present in the packet, indicates at least one RU the packet is intended for. When the RU identification is present in the packet, the at least one ETHERNET switch is also configured to communicate, for each of the at least one RU, at least a portion of the packet to the RU based on a comparison of the RU identification with at least one bit pattern for the RU.
