Distributed Interactive Simulation
Distributed Interactive Simulation (DIS) is a standardized protocol primarily used for enabling real-time platform-level wargaming across multiple locations. It facilitates interaction and communication between simulators by exchanging data such as entity states and environmental effects, thus allowing complex, interoperable simulation environments. Port 3000 serves as a commonly modifiable default UDP port used in DIS deployments..
Distributed Interactive Simulation (DIS) is a protocol based on IEEE 1278 standards designed to enable multi-platform joint training and simulation exercises in real-time. It allows geographically distributed simulations — such as flight simulators, battlefield systems, or naval trainers — to share data effectively, creating a synchronized simulation 'world'. Data exchanged typically includes information about the state, interactions, and movements of simulated entities.
Port 3000 is often designated as a default, but modifiable, UDP port for DIS communication. Due to the broadcast nature of simulation data and emphasis on low latency, DIS primarily relies on UDP transport. It enables time-sensitive and high-volume data transfers required to maintain immersive and responsive multiplayer simulation experiences.
DIS networks are flexible and support both multicast and broadcast transmission modes, with UDP offering simplicity in deployment. Because it is a modifiable default, administrators often change the port to avoid collisions or enhance security by obscurity. However, in many test or default configurations, port 3000 remains in wide use as the entry point for DIS traffic.
