For Improving the interoperability, reusability and composability of simulation resources, creating a unified Live-Virtual-Constructive (LVC) integrated simulation architecture has always been a major goal in the modeling and simulation (M&S) field. This paper summarizes the creation process and potential architectures involved. Firstly, the developing history of distributed simulation architecture is introduced from SIMMNET to JLVC2020. Then, the simulation architectures of TENA, JLCV Federation and JLVC2020, which have great potential in the future, are elaborated. Finally, the near-to medium-term future construction plan of LVC integrated simulation architecture is given through three development routes. The related discussion has important reference value for promoting the construction capacity of joint training simulation.
