Delaying Packets¶

The PacketDelayer module delays packets for a configured amount of time.

In this example network, packets are produced periodically by an active packet source (ActivePacketSource). The produced packets are delayed (PacketDelayer) for a random amount of time. Finally, the packets are pushed into a passive packet sink (PassivePacketSink).

    @display("bgb=600,200");
    submodules:
        producer: ActivePacketSource {
            @display("p=100,100");
        }
        delayer: PacketDelayer {
            @display("p=300,100");
        }
        consumer: PassivePacketSink {
            @display("p=500,100");
        }
    connections allowunconnected:
        producer.out --> delayer.in;
        delayer.out --> consumer.in;
}
