Strategy of object synchronization for DIS based on RT-TCP/IP

According to current certain disadvantage of Application of DIS, we built a DIS system on real-time Ethernet. According to characteristics of RT-TCP/IP environment, Object Interaction PDU was redesigned, four basic RT-PDU which include methods of create Object, delete object, execute object and modify the object property were built. Based on HLA data management ideas, the data distribution mechanism was designed to guarantee the system's real-time performance and reliability. In the distributed simulation application of an aircraft air defense system, it is shown that this object synchronization strategy has good practicality.
