Distributed Interactive Simulation (DIS) is an IEEE standard for conducting real-time platform-level gaming across multiple host computers and is used worldwide, especially by military organizations but also by other agencies such as those involved in space exploration and medicine.

The IEEE Distributed Interactive Simulation (DIS) networking-protocol standard can be used for synchronized virtual environments and Live, Virtual, Constructive (LVC) simulations. Ongoing development work and DIS details are maintained by the Simulation Interoperability Standards Organization (SISO) which includes the DIS Product Development Group (PDG).

X3D nodes that include DIS support are X3D nodes that include DIS support are EspduTransform, DISEntityManager, DISEntityTypeMapping, ReceiverPdu, SignalPdu and TransmitterPdu.
