Vehicle networking system testing and characterization

A system comprising:

• one or more computer processors;
• and
• one or more computer-readable mediums storing instructions that, when executed by the one or more computer processors, cause the system to perform operations comprising:
• determining, based on sensor data describing a current state of a vehicle, to execute a testing mode of a vehicle networking system of the vehicle, the vehicle networking system including a set of preset mechanisms, a set of packet injectors, and a set of logging mechanisms;
• in response to determining to execute the testing mode of the vehicle networking system:
• causing the set preset mechanisms to configure a set of nodes of the vehicle networking system into specified states to achieve a first configuration state of the vehicle networking system;
• and
• while the vehicle networking system is in the first configuration state, causing the set of packet injectors first packet injector to transmit synchronized sequences of data packets within the vehicle networking system;
• gathering, from the set of logging mechanisms located within the vehicle networking system, diagnostic data describing data packet transmissions in the vehicle networking resulting from transmission of the synchronized sequences of data packets by the set of packet injectors, the diagnostic data generated by the set of logging mechanisms as data packets traverse through each logging mechanism from the set of logging mechanisms, the diagnostic data including data identifying data packets detected by each logging mechanism and timestamps indicating times at which the data packets were detected by each logging mechanism;
• and
• generating, based on the diagnostic data and an expected diagnostic data, a testing report describing performance of the vehicle networking system during the testing mode.
