| Abstract: | Distributed interactive simulation(DIS) is widely used in various area, such as industry, commerce, entertainment, military, and so on. High level architecture(HLA) is a new simulation technology framework proposed by US DoD in order to solve the problem of interoperability and reusability among various kinds of simulations. Future distributed interactive simulation will be built on internet, it faces the challenge of system scalability. This paper introduces the briefhistory and the developing trends of DIS, then introduces the HLA-a new generation simulation technology framework and the its characteristics. Finally this paper discusses the advantages of multicast communication and its use in the implementation of data filtering scheme under HLA framework. |
