virtual void ns3::DcaTxop::Dcf::DoNotifyAccessGranted ( void )

inlineprivatevirtual

Called by DcfManager to notify a DcfState subclass that access to the medium is granted and can start immediately.

Implements ns3::DcfState.

Definition at line 53 of file dca-txop.cc.

Here is the call graph for this function:

virtual void ns3::DcaTxop::Dcf::DoNotifyChannelSwitching ( void )

inlineprivatevirtual

Called by DcfManager to notify a DcfState subclass that a channel switching occured.

The subclass is expected to flush the queue of packets.

Implements ns3::DcfState.

Here is the call graph for this function:

virtual void ns3::DcaTxop::Dcf::DoNotifyCollision ( void )

inlineprivatevirtual

Called by DcfManager to notify a DcfState subclass that a normal collision occured, that is, that the medium was busy when access was requested.

The subclass is expected to start a new backoff by calling DcfState::StartBackoffNow and DcfManager::RequestAccess is access is still needed.

Implements ns3::DcfState.
