Passive Source - Active Sink
============================

This step demonstrates the :ned:`ActivePacketSink` and :ned:`PassivePacketSource` modules.
The active packet sink (:ned:`ActivePacketSink`) periodically pops packets from the
passive packet source (:ned:`PassivePacketSource`).

The active packet sink module has a configurable collection interval. The passive packet
source also has a configurable providing interval, which limits the times at which packets
can be popped from the module.
