The creation of the synthetic, virtual battlefield at the 14th I/1TSEC in San Antonio demonstrated the feasibility of the use of the non proprietary Distributed Interactive Simulation (DIS) protocols for the interoperability of dissimilar simulations. Although a major milestone has been reached in the demonstration of the ability of dissimilar simulators to communicate with the DIS protocol, true interoperability has yet to be determined. The actual interoperability of the players cannot be assessed until a thorough review the individual player's action and response has been made.

During the demonstration, a data logger developed by Concurrent Computer Corporation was used to collect all message traffic on the DIS network. Grumman, in conjunction with Concurrent, has begun a post mission review of the data collected. This paper will describe the findings of this review. A comparison of how the actual network traffic compared with the predicted assumptions, and how the use of the next order dead reckoning algorithms may impact the network traffic will be made. Discrepancies as a result of differences in the terrain database and interpretations of the rules of engagement will be pointed out. This paper will also include the "lessons learned" from this review process.
