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

packet

the first fragmented packet

Referenced by ns3::MacRxMiddle::HandleFragments().

Here is the caller graph for this function:

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

packet

the received fragment

Definition at line 120 of file mac-rx-middle.cc.

References m_defragmenting, m_fragments, and NS_ASSERT.

Referenced by ns3::MacRxMiddle::HandleFragments().

Here is the caller graph for this function:

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

packet

the last fragment

Returns

the fully reconstructed packet

inline

Return the last sequence control we received.

Returns

the last sequence control

Here is the caller graph for this function:

IsDeFragmenting()

bool ns3::OriginatorRxStatus::IsDeFragmenting ( ) const

inline

Check if we are de-fragmenting packets.

Returns

true if we are de-fragmenting packets, false otherwise

Referenced by ns3::MacRxMiddle::HandleFragments().

Here is the caller graph for this function:

IsNextFragment()

bool ns3::OriginatorRxStatus::IsNextFragment ( uint16_t  sequenceControl ) const

inline

Check if the sequence control (i.e.

fragment number) is in order.

Parameters

sequenceControl

the raw sequence control

Returns

true if the sequence control is in order, false otherwise

Set the last sequence control we received.

Parameters

sequenceControl

the last sequence control we received
