VR-Exchange

VR-Exchange is an universal translator for distributed simulation.
With VR-Exchange, you can link together simulations that use different HLA RTIs, different object models, and even different protocols.

The VR-Exchange architecture consists of a protocol-independent Data Exchange, and a Broker for each supported protocol. Each Broker runs as a separate process, and trades data with the other Brokers through the Data Exchange - a shared memory interface.
