分布式实时飞行仿真中的联接技术

Interconnecting Technique of Distributed Real-Time Flight Simulation

分布式仿真系统可采用的联接方式主要有物理共享内存总线、消息传递网络和复制共享内存网络三种。物理共享内存总线和消息传递网络在分布式实时仿真中存在技术上的不足,但它们之间具有一定的互补性,复制共享内存网络将它们两者的优点有机地结合起来,成为一种适用于实时系统分布式仿真的理想方式,文章对这些技术分别进行了阐述。最后,针对分布式飞行仿真的特殊要求,介绍了复制共享内存网络的具体应用。

Physical shared memory bus, message translating LAN and copy shared memory network are the main interconnecting technology using in distributed real-time simulation. The former two do not very satisfy the real-time simulations, but copy shared memory network combines their advantages. It＇s the preferable interconnecting technology of distributed real time system simulation. All of them were described. In the end, the application of copy shared memory network was discussed according to the specific request of distributed flight simulation.
