Latenz

Definition

Latenz ist die Zeitverzögerung zwischen dem Senden eines Datenpakets von einer Quelle und dessen Empfang am Ziel, typischerweise in Millisekunden (ms) gemessen.

Erklärung

Transatlantic fiber latency is roughly 70–80 ms due to the physical speed of light in glass (~200,000 km/s). Satellite internet adds ~600 ms for geostationary orbits, making real-time gaming impractical. For interactive applications, latency below 20 ms feels instantaneous; above 150 ms, users notice delays. Latency is distinct from bandwidth: a high-bandwidth pipe can still have high latency.
