Abstract : The Synthetic Theater of War-Europe (STOW-E) distributed simulation demonstration was conducted 47 November 1994. This exercise linked 16 sites around the world in a single virtual battlespace. Live, virtual, and constructive forces representing all four DoD services participated in a joint operation involving land, sea, and air engagement. One of the critical technologies demonstrated in the STOW-E was Scaleability. The goal of the Scaleability effort was to support the evolution of Distributed Interactive Simulation (DIS) technology by pushing back the limitations on the number of entities that could participate in an exercise. The Scaleability challenge for STOW-E was to reduce the traffic generated by the participating simulations to the 1.1 megabit-per-second (Mbps) capacity of the tail circuits of the Defense Simulation Internet (DSI). The Scaleability solution was to reduce the DIS traffic load offered to the DSI wide area network (WAN) by using seven bandwidth-demand reduction techniques (BRTs). The algorithms were as follows: (1) Protocol Data Unit (PDU) Culling; (2) Broadcast Grid Filtering; (3) Quiescent Entity Determination (QED); (4) Protocol Independence Compression Algorithm (PICA); (5) Bundling; (6) Overload Management; (7) LAN Filtering. These algorithms were housed in Application Gateways (AG) that operated in series between the DSI WAN and the simulation LAN (ETA/ATI, 1994).
