What it shows

  • Incoming requests enter a FIFO queue regardless of arrival irregularities.
  • The bucket leaks requests at a steady, strictly controlled constant rate.
  • When the buffer reaches max capacity, overflowing requests drop instantly.

The takeaway

Leaky buckets transform unpredictable traffic spikes into a smooth, constant-rate stream of execution.
