Abstract: A gateway processor coordinates communication among an autonomous vehicle components boundary domain, a vehicle boundary domain, and an oversight server. The gateway processor receives a message from the oversight server. The gateway processor determines a priority level, a domain tag data, and destination data associated with the message. The priority level indicates a scheduling requirement associated with the message. The domain tag data indicates that the message is associated with a particular domain from among the autonomous vehicle components boundary domain, the vehicle components boundary domain, or the security domain. The destination data indicates that the message is designated to a particular component within the particular domain. In response, the gateway processor schedules the message to be transmitted to the particular domain. The gateway processor routes the message to the particular component.
