The Distributed Interactive Simulation (DIS) Product Support Group (PSG) is a permanent support group chartered by the SISO SAC to support DIS products such as the IEEE 1278 series of standards. It exists to provide support even when no DIS PDG is currently active and working on a new version of a DIS standard.
The DIS PSG supports the distributed simulation community by acting as a forum and library for DIS-related information; providing technical support to users and developers by answering questions; providing contact information for experts in different areas; and maintaining a library of distributed simulation documentation. The DIS PSG is also the place where Problem/Change Requests (PCRs) can be initially submitted or commented on for changing the 1278 series of IEEE DIS Standards and where the individual PCRs and PCR Status Reports are maintained for download.
The DIS PSG publishes, maintains, and updates a series of reference documents related to DIS that are helpful to users and developers. These documents consist of the following:
SISO-REF-010: Enumerations for Simulation Interoperability
SISO-REF-020: DIS Plain and Simple (in work)
SISO-REF-030: DIS Extensions (proposed)
The DIS PSG closely coordinates with the DIS PDG (when the DIS PDG is active and producing a new version of a 1278 series standard), the DIS Enumeration discussions, and others to ensure that the entire distributed simulation community is kept appraised of DIS developments. Not all DIS users are members of all three groups (DIS PDG, DIS ENUM and the DIS PSG) so cross-coordination is essential.
