What does network throughput measure?

Throughput measures data successfully transmitted in a given time.

  1. Successfully transmitted data over time ✔
  2. The maximum theoretical transfer rate
  3. Only the first packet's delay

Why: Throughput is the rate actually achieved by successful data transfer. Congestion, loss, protocol overhead, and hardware limits often keep it below the connection's theoretical bandwidth.

Huh, didn't know that: Comparing throughput with bandwidth helps show how efficiently a link is being used.

The dad joke
Throughput finished the job while bandwidth discussed its potential.
