You don't want to always drop the packet that seems to exceed the
threshold of link capacity you allocated. Doing that tends to cause
unfair treatment when two or more TCP connections are running simultaneously
over the same connection.
Dropping a random packet from the queue was invented to overcome that
unfairness.
