Messaging system with protocol independent message format

摘要

A messaging system includes a message bus and a first processing device. The message bus is adapted to transmit a first message. The first message includes a second message, and the second message includes at least a first command. The first processing device is coupled to the message bus. The first processing device includes a message interface adapted to receive the first message and extract the second message independent of the first command. An input queue is adapted to store the second message. A message interpreter is adapted to retrieve the second message from the message queue and decode the second message to identify the first command. A method for communicating messages includes transmitting a first message over a message bus. The first message includes a second message, and the second message includes at least a first command. The first message is received and the second message is extracted independent of the first command. The second message is stored in an input queue. The second message is retrieved from the message queue. The second message is decoded to identify the first command.
