Abstract
A real-time protocol for real-time network programming applications is disclosed. The protocol is executable on a computer network having a plurality of nodes that include applications, a network stack, an operating system, and middleware capable of executing real-time operations. The protocol can use group objects to model physical and logical devices connected to the network wherein each group object comprises at least one variable. Changes in these variables are encapsulated in variable change messages which are propagated in the network using communication objects. Also described is a real-time messaging format useful for implementing the protocol.
