Detailed Description

LTE_RLC Saturation Mode (SM): simulation-specific mode used for experiments that do not need to consider the layers above the LTE_RLC.

The LTE_RLC SM, unlike the standard LTE_RLC modes, it does not provide data delivery services to upper layers; rather, it just generates a new LTE_RLC PDU whenever the MAC notifies a transmission opportunity.

Member Function Documentation

◆ DoDispose()

void ns3::LteRlcSm::DoDispose ( )

overridevirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Reimplemented from ns3::LteRlc.

Definition at line 201 of file lte-rlc.cc.

References ns3::LteRlc::DoDispose(), and NS_LOG_FUNCTION.

Here is the call graph for this function:

◆ DoInitialize()

void ns3::LteRlcSm::DoInitialize ( )

overridevirtual

Initialize() implementation.

This method is called only once by Initialize(). If the user calls Initialize() multiple times, DoInitialize() is called only the first time.

Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject() and AggregateObject() from within this method.

Here is the call graph for this function:

◆ DoNotifyHarqDeliveryFailure()

void ns3::LteRlcSm::DoNotifyHarqDeliveryFailure ( )

overridevirtual

Notify HARQ delivery failure.

Implements ns3::LteRlc.

References NS_LOG_FUNCTION.

◆ DoNotifyTxOpportunity()

void ns3::LteRlcSm::DoNotifyTxOpportunity ( LteMacSapUser::TxOpportunityParameters params )

overridevirtual

Notify transmit opportunity.

Parameters

params LteMacSapUser::TxOpportunityParameters

For RLC SM, the packets are not passed to the upper layers, therefore, in the absence of an header we can safely byte tag the entire packet.

Implements ns3::LteRlc.
