This paper presents a simple and efficient switched Ethernet communication protocol for indus-trial control network real-time communication. The protocol does not need any modifications in the Ethernet hardware and coexists with TCP/IP suites, and then support both real-time traffic and non real-time traffic. Compared to some conventional hard real-time network protocols, the proposed one has better real-time performances and meets the requirements for the practical applications of real-time systems.
