IEEE Std 1278.2-2015 pdf download – IEEE Standard for Distributed Interactive Simulation (DIS)— Communication Services and Profles.
The PDUs detailed in IEEE Std. 1278.1™ define the common language by which simulation applications communicate. This includes simulators of different and unrelated design and architecture, including instrumented live platforms and virtual and constructive simulations. The only restriction placed on the participating simulator or site is the way it communicates within a DIS exercise. Where the DIS PDUs define the information passed between simulation applications, this standard defines how the host computers for those simulation applications can be connected in a modular fashion to facilitate the communication at the local and global levels. This will be done through the required use of communications standards that promote interoperability.
2. Normative references The following referenced documents are indispensable for the application of this document (i.e., they must be understood and used, so each referenced document is cited in text and its relationship to this document is explained). For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments or corrigenda) applies.
The simulation application represents or simulates real world phenomena for the purpose of training or experimentation. Examples of simulation applications include manned vehicle simulators, computer generated forces, environment simulators, and computer interfaces between a distributed interactive simulation (DIS) network and real equipment. The simulation application receives and processes information concerning entities created by peer simulation applications through the exchange of DIS protocol data units (PDUs). More than one simulation application may can simultaneously execute on a host computer. The simulation application is the application layer protocol entity that implements the protocol defined in this standard.
NOTE— PDUs addressed with broadcast do not typically pass through routers so it is limited to simple LAN topologies. Gateways are required to convert broadcast addressing into either multicast or unicast to allow more complex network topologies. Multicast addressing, a more general form of addressing, shall allow one-to-many communication to a group that is a subset of all host computers and shall allow individual simulation applications to join a group of interest. Multicast addressing should be supported by all simulation applications.
