Detailed Description

A class to keep track of the packet originator status.

It recomposes the packet from multiple fragments.

Member Function Documentation

◆ AccumulateFirstFragment()

void ns3::OriginatorRxStatus::AccumulateFirstFragment ( Ptr< const Packet packet)
inline

We have received a first fragmented packet.

We start the deframentation by saving the first fragment.

Parameters
packetthe first fragmented packet

◆ AccumulateFragment()

void ns3::OriginatorRxStatus::AccumulateFragment ( Ptr< const Packet packet)
inline

We received a fragmented packet (not first and not last).

We simply save it into our internal list.

Parameters
packetthe received fragment

◆ AccumulateLastFragment()

Ptr<Packet> ns3::OriginatorRxStatus::AccumulateLastFragment ( Ptr< const Packet packet)
inline

We have received a last fragment of the fragmented packets (indicated by the no more fragment field).

We re-construct the packet from the fragments we saved and return the full packet.

Parameters
packetthe last fragment
Returns
the fully reconstructed packet

◆ IsDeFragmenting()

bool ns3::OriginatorRxStatus::IsDeFragmenting ( void  ) const
inline

Check if we are de-fragmenting packets.

Returns
true if we are de-fragmenting packets, false otherwise

Check if the sequence control (i.e.

fragment number) is in order.

Parameters
sequenceControlthe raw sequence control
Returns
true if the sequence control is in order, false otherwise
