Research And Application Of Real-Time Performance In Distributed System Based On LAN

This paper is to study and enhance the real-time performance in distributed real-time system. In this paper, we put forward an architecture model to descript distributed real-time system, and advance a real-time transmission protocol, following we try to apply a method to enhance the real-time performance in distributed system, in the method we bind real-time operation system together with dynamic real-time transmission protocol to make use of their capability farthest, later we apply this method to naval chain of command.First we bring in the fundamental theory of real-time system and distributed system. Then we use a general architecture model of distributed system for reference, by adding a part of non-real-time kernel in the kernel layer, we ameliorate the architecture model and apply it to frame the naval chain of command. In order to adjust demand of naval chain of command, we boost the general real-time transmission protocol by adding measures to the old protocol in the aspect of data transferring and reliability by software, after we call the improved protocol dynamic real-time transmission protocol. As an innovation in real-time performance research and design, we try to improve the real-time performance by using capability of both VxWorks and real-time transmission protocol furthest. Finally this method is validated by using and testing in naval chain of command.
