Connecting Multiple Active Sources to a Passive Sink
====================================================

The :ned:`PacketMultiplexer` module connects to multiple active packet sources on its
inputs, and pushes all incoming packets onto a passive packet sink on its single output.

In this example network, packets are produced at random intervals by several active
packet sources (:ned:`ActivePacketSource`). The packets are consumed by a single passive
packet sink (:ned:`PassivePacketSink`) upon arrival. The single sink is connected to
multiple sources using an intermediary component (:ned:`PacketMultiplexer`) which simply
forwards packets.
