A deterministic network is required for motion control where actuation must occur within a fixed, bounded time every cycle. Which characteristic most defines a deterministic industrial network?
- A.Best-effort delivery with retransmission on loss
- B.Guaranteed bounded latency and jitter so messages arrive within a predictable time window
- C.Maximum throughput regardless of timing
- D.Dynamic routing that reroutes around congestion unpredictably
Why B is correct
Determinism means traffic is delivered within guaranteed, bounded latency and jitter every cycle, which closed-loop motion control depends on. Best-effort networking cannot promise the timing such control loops require.
