Idle listening

Idle Listening ( Engl. "Idle listening". See idle ) is known in computer networks the unwanted usually fact that a terminal is listening the communication medium, although no communication takes place. The listener wastes time and energy.

If communication is initiated in the computer network without prior notice and without notification via another communication channel, idle listening is the only way to receive messages. The physical carrier test also uses short periods of idle listening to find out whether the communication medium is free.

If the listener does not hear the empty medium, but rather communication from other network participants, one speaks of overhearing .
