Optimistic Synchronization
synchronization transparency: federates should not need to know what synchronization mechanism is used locally by other federates
prevent conservative federates from receiving erroneous events
allow optimistic federates to receive (possibly) erroneous events
mechanisms required for event cancellation, GVT computation
- allow events to be processed out of time stamp order
- use a roll back mechanism to erase incorrect computations
- may send erroneous messages; unsend via event cancellation (anti-messages)
