1. A computer-implemented method when executed by data processing hardware causes the data processing hardware to perform operations comprising:
configuring a ping interval protocol for an electronic control unit (ECU);
connecting the ECU to a data network including a packet firewall;
establishing a message queueing telemetry transport (MQTT) session corresponding to the data network;
detecting a ping status of the ping interval protocol relative to the packet firewall;
determining, automatically, an optimal ping interval for the ping interval protocol based on the ping status;
constructing a ping interval topic for the MQTT session including the determined optimal ping interval;
publishing the determined optimal ping interval to the ping interval topic; and
sharing the optimal ping interval with a subscribed electronic control unit (ECU) to the ping interval topic, wherein publishing the ping interval topic includes issuing an optimal ping interval value notification to the subscribed ECU.
