Abstract
A method of communicating messages between modules in a system on a vehicle, each module configured as a publisher node and/or subscriber node, the publisher nodes and the subscriber nodes collectively forming a plurality of nodes that communicate in the operation of the vehicle. One method includes communicating, by a subscriber node, with a registry for information to determine if a new message associated with a first topic is available for reading, determining, by each subscriber node, if a new message associated with the first topic is available for reading, in response to determining a new message associated with the first topic is available for reading, reading from the registry location information indicating where the first message is stored in a first message buffer, and reading, by each subscriber node the first message from the first message buffer using the location information.
