An extended TCP/IP protocol over the local area network for DCCS

摘要

This paper proposes an extended TCP/IP protocol over local area networks, that can be used for soft real-time systems including distributed computer control systems and manufacturing automation systems. Because the proposed protocol extends the standard TCP/IP, all the existing application softwares can be used with the proposed protocol without modification. The proposed TCP/IP also provides the periodic transmission mode(PTM), which provides a very efficient transmission method of the periodical data for rea-time monitoring and control systems. With PTM, the periodical data collection and updating the control signals are possible with relatively small traffic overhead. This paper includes the computer simulation results, and the prototype system has been applied and evaluated to the large scale distributed control systems and human-like robot systems.
