Network Latency Calculator
Calculate minimum and typical network latency based on physical distance, transmission medium, and number of hops. Understand propagation delay for networking.
How to Use the Latency Calculator
- Enter physical distance in kilometers.
- Select transmission medium (fiber, copper, or wireless).
- Enter number of network hops.
- Click Calculate to get minimum and typical latency.
Casos de Uso
- •Planning network architecture for latency-sensitive applications.
- •Understanding CDN edge node placement benefits.
- •Evaluating data center locations for global services.
- •Teaching networking fundamentals.
Fórmula
Propagation delay = distance / signal speed. Typical RTT = 2 × propagation + hop delay + processing overhead.
Preguntas Frecuentes
What is propagation delay?
Propagation delay is the time for a signal to travel from source to destination through a medium.
How fast does light travel in fiber?
Light in fiber travels at about 200,000 km/s (2/3 of the speed of light in vacuum due to refractive index).
What latency should I expect for cross-continental connections?
New York to London (~5,500 km via fiber): ~27ms one-way, ~55ms round-trip minimum.
