Data analysis and configuration of a distributed radio access network

A distributed radio access network (RAN), comprising:

• a plurality of remote units (RUs), each being configured to exchange radio frequency (RF) signals with at least one user equipment (UE);
• a central unit communicatively coupled to the plurality of RUs via a fronthaul network comprising one or more ethernet switches;
• at least one processor located in the central unit, the RUs, or a combination thereof, wherein the at least one processor configured to:
• receive diagnostic information relating at least to processing performed for at least two layers of an air interface implemented by the distributed RAN;
• identify a system performance problem based on the diagnostic information using at least one policy;
• search for a cause of the system performance problem using at least a portion of the diagnostic information and at least one trigger in the at least one policy;
• and
• when the cause of the system performance problem is identified using the at least a portion of the diagnostic information, determine at least one action to correct, limit, or circumvent the system performance problem.
