Scenario
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.Maximum throughput regardless of timing, which NIST SP 800-82 ranks above network segmentation for protecting control networks
- B.Best-effort delivery with retransmission on loss
- C.Dynamic routing that reroutes around congestion unpredictably within a bounded scan cycle
- D.Guaranteed bounded latency and jitter so messages arrive within a predictable time window
Why D 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.
