Joint Test Inter-Connection Architecture (JTICA) contains application layer, simulation layer, and communication layer from top to bottom, which can construct a shared test space through connecting live, virtual, constructive simulation resources. Data distribution service is used as communication layer protocol, which can provide joint test with high real-time and large throughput. Heterogeneous systems and interactive models need to been mapped into equivalent entities in communication layer to set up the relationship between heterogeneous systems based on data-centric publish subscribe mechanism. Then heterogeneous systems are mapped into DomainParticipant, interactive models mapped into Topics, in communication layer. There are two map relationships between heterogeneous systems and DomainParticipants including “one-to-one” and “one-to-many”, which affect the communication efficiency of joint test. Communication delay of Prototype systems designed based on different map relationship are compared, and the result is referred to when selecting map relationship.
