Abstract:

Distributed Interactive Simulation (DIS) is getting a major overhaul for its next version. The redesign greatly simplifies the protocol formats, reduces the number of PDUs and makes it easier to add capability, enabling DIS for a more capable and longer future.

The Simulation Interoperability Standards Organization (SISO) DIS Product Development Group (PDG) has nearly completed the DIS V8 draft to be considered for adoption by the IEEE. This new version will break the backwards compatibility required by previous generations in order to bring several new capabilities and address existing issues.

This paper will cover the top ten improvements that have been made in the DIS V8 standard compared to DIS V7 including:

Extensibility through a new PDU Design
SISO-REF-030 yearly updates to capability/reusable records
Improved RF modeling of AESA radar and advanced jammers
Combined Parabolic Circular Dead Reckoning algorithm to reduce PDU rates
Multiple Entity PDUs to allow higher entity counts with dramatically fewer PDUs
Partial Updates/Split Modeling of systems and reliability in all SIMAN PDUs
XML schema to support automated marshalling code and Wireshark dissectors
New PDUs including Interactive IFF, Communications Node, Application Control and Laser PDUs
Simplified Gridded Data PDU with weather support
Miscellaneous small updates like a 64-bit timestamp and Little Endian data representation

While DIS V8 will not be on the wire compatible with DIS V7 it will be possible to use gateways to translate all of the DIS V7 data into DIS V8 allowing interoperability as systems are upgraded. DIS V8 data may be translated to DIS V7 to some extent, but new PDUs and concepts will not be translateable.

DIS V8 is the biggest change to be made to the DIS standard since it’s beginning, and we will cover the top 10 improvements that have been made in the standard.
