Leaky bucket different methods of applying this leaky bucket analogy are described in the literature. These give what appear to be two different algorithms, both of which are referred to as the leaky bucket algorithm and generally without reference to the other method.

In one version of applying the analogy, the analogue of the bucket is a counter or variable, separate from the flow of traffic or scheduling of events. This counter is used only to check that the traffic or events conform to the
