Deterministische Netze (EN)

Definition

A deterministic network guarantees that data packets reach their destination within a predictable, maximum time frame. This property is essential in production technology, as control commands and sensor values are time-critical. Jitter (temporal variations) must be minimized to ensure synchronized and stable automation and to maintain process security in industrial environments.
