1. A method of analyzing an Open Radio Access Network (O-RAN) fronthaul (OFH) link between an O-RAN Distributed Unit (O-DU) and an O-RAN Radio Unit (O-RU), comprising:
receiving an OFH packet traffic flow from the O-DU and the O-RU;
adding timing information to each packet of the OFH packet traffic flow;
parsing metadata from packet headers of the OFH packet traffic flow;
identifying one or more active packet flows in the OFH packet traffic flow using the parsed metadata;
tracking the identified one or more active packet flows using the parsed metadata;
continuously generating one or more analytical timing measurements of the tracked one or more active packet flows based on the parsing and the added timing information;
receiving user input selecting at least one selectable parameter, wherein a selectable parameter comprises at least one of the O-DU, the O-RU, a type of packet, a communication plane, a source, a destination, a traffic direction, or at least one of the one or more analytical timing measurements,
wherein receiving user input comprises receiving user input selecting at least one selectable parameter comprising the O-DU; and
presenting, using the selected at least one selectable parameter, a visual representation of the tracked one or more active packet flows and the continuously generated one or more analytical timing measurements of the tracked one or more active packet flows,
wherein the presented visual representation comprises a graphical user interface (GUI) showing a current transmission bandwidth of the O-DU and at least one of current reception bandwidth of the O-DU, transmission bandwidth usage of the O-DU over time, reception bandwidth usage of the O-DU over time, or an identification of each O-RU presently connected to the O-DU.
