Detailed Description

A class to keep track of the packet originator status.

It recomposes the packet from multiple fragments.

Member Function Documentation

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

Definition at line 78 of file mac-rx-middle.cc.

References NS_ASSERT.

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

Here is the caller graph for this function:

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 113 of file mac-rx-middle.cc.

References NS_ASSERT.

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

Here is the caller graph for this function:

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

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

Here is the caller graph for this function:

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

inline

Check if we are de-fragmenting packets.

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

References m_defragmenting.

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

Here is the caller graph for this function:

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

void ns3::OriginatorRxStatus::SetSequenceControl ( uint16_t sequenceControl )

inline

Set the last sequence control we received.

Parameters

sequenceControl the last sequence control we received
