Member Function Documentation

◆ AddHeader()

void PieQueueDiscTestItem::AddHeader ( )

overridevirtual

Add the header to the packet.

Subclasses may keep header and payload separate to allow manipulating the header, so this method allows to add the header to the packet before sending the packet to the device.

Implements ns3::QueueDiscItem.
