Clock Synchronization Method for Distributed Real-Time Simulation Based on Multilayer Network Architecture

摘要

In order to achieve synchronous propulsion of real-time distributed simulation based on multi-layer network, this paper designed a clock synchronization method for this multi-layer architecture. The realization of Real-time Ethernet Layer's synchronization is based on industrial Ethernet PowerLink protocol, and the realization of Hard Real-time Layer's clock synchronization is take advantage of the reflective memory card's Network Interrupt. This paper also designed the Interlayer clock alignment strategy between Real-time Ethernet Layer and Hard Real-time Layer. The test results show that the overall performance can meet the requirements of millisecond-level real-time simulation system.
