摘　　要：针对航空、航天分布试验与仿真系统对透明数据实时交互的需求,所设计的虚拟共享内存中间件,提高了系统的实时性。然而在负载很大的情况下,VSM的稳定性较差。针对分布试验对VSM高负载下的稳定性需求,提出了一种基于发布订阅的VSM中间件的改进方案,优化了网络通信,提高了VSM中间件在高负载下的稳定性,加强了实时性能。The VSM（Virtual Share Memory） middleware,which is design for satisfying the demand of transparent real-time data interactive in aerospace distributed simulation test system,improve the real-time performance in distributed simulation system.But the stability of VSM in high payload is not satisfactory.Aiming to the demand of high stability in high payload of distributed simulation using VSM middleware,the scheme of VSM middleware base on publish/Subscribe is proposed.Through optimized the network transmission,the stability and real-time performance is improved by the VSM base on publish/subscribe in high payload.
