Radio Frequency (RF) networks have a limited bandwidth compared to landlines. Therefore, when operating over RF, it is desirable to use the available bandwidth with the greatest efficiency possible. The Compressed Distributed Interactive Simulation (C-DIS) standard developed by the Air Force Research Laboratory (AFRL) is a compressedformat version of the IEEE 1278.1-2012 Distributed Interactive Simulation (DIS) standard that significantly increases transmission efficiency. It is a government owned, non-proprietary standard. C-DIS is a bit-oriented data standard that reduces the size of DIS packets by 50-to-70 percent, effectively more than doubling the bandwidth of a network. The C-DIS standard will be used on the 5G-Advanced Training Waveform (5G-ATW) RF network as part of the Secure Live Virtual Constructive Advanced Training Environment (SLATE) Advanced Technology Demonstration (ATD).
C-DIS maintains all of the currently used DIS Protocol Data Unit (PDU) fields, concepts, approaches and enumerations, making translation from DIS to C-DIS and from C-DIS back to DIS efficient and accurate. It is intended to be used as a transport-level compression that allows DIS data to be readily compressed by transmitters and decompressed by receivers. C-DIS supports current standard SISO and CAF DMO enumerations and values and allows for future enumeration growth.
In addition to standard DIS messages, C-DIS also supports compression of the CAF DMO-defined messages used for Active Electronically Steered Antenna (AESA) Radars and Advanced Jammers. These messages include the Radar Track Report, Jammer Report Record, and Jammer False Targets Record. This enables the modeling of Electronic Attack and Jamming over the limited bandwidth RF network available for Live Virtual Constructive operations.
This paper discusses C-DIS compression techniques, message formats, usage rules, and performance results.
