Abstract: Because the network of Launch Control System (LCS) handles a volume of critical data in a server environment and a minor fault in the network can cause uncontrollable status during periods of launch campaign time, the network should provide the very reliable service. To achieve the goal, this paper discusses what requirements the network expects and what differences the network has comparing to other common networks. After considering requirements, differences and compatibility with Supervisory Control and Data Acquisition (SCADA) system, the physical and logical configurations for the LCS network are proposed to improve the reliability and efficiency. The experimental results show what values in failover parameters are the most suitable for the LCS network. And other results and traffic shapes which are measured during practical operational period confirm that the traffic and processing load are effectively redistributed as planned.
Keywords: Fault tolerance network, Industrial network, Launch Complex (LC), LCS, SCADA.
