Member Function Documentation

◆ AddHeader()

void PrioQueueDiscTestItem::AddHeader ( void  )
virtual

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.

Definition at line 71 of file prio-queue-disc-test-suite.cc.

◆ Mark()

bool PrioQueueDiscTestItem::Mark ( void  )
virtual

Marks the packet as a substitute for dropping it, such as for Explicit Congestion Notification.

Returns
true if the packet gets marked, false otherwise

Implements ns3::QueueDiscItem.
