Statistical Policing
====================

Goals
-----

In this example we combine a sliding window rate meter with a probabilistic packet
dropper to achieve a simple statistical policing.

The Model
---------

In this configuration we use a sliding window rate meter in combination with a
statistical rate limiter. The former measures the thruput by summing up the
packet bytes over the time window, the latter drops packets in a probabilistic
way by comparing the measured datarate to the maximum allowed datarate.
