The Prio qdisc is a simple classful queueing discipline that contains an arbitrary number of classes ...
void SetBandForPriority(uint8_t prio, uint16_t band)
Set the band (class) assigned to packets with specified priority.
~PrioQueueDisc() override
Ptr< const QueueDiscItem > DoPeek() override
Return a copy of the next packet the queue disc will extract.
Ptr< QueueDiscItem > DoDequeue() override
This function actually extracts a packet from the queue disc.
uint16_t GetBandForPriority(uint8_t prio) const
Get the band (class) assigned to packets with specified priority.
bool CheckConfig() override
Check whether the current configuration is correct.
PrioQueueDisc()
PrioQueueDisc constructor.
Priomap m_prio2band
Priority to band mapping.
bool DoEnqueue(Ptr< QueueDiscItem > item) override
This function actually enqueues a packet into the queue disc.
static TypeId GetTypeId()
Get the type ID.
void InitializeParams() override
Initialize parameters (if any) before the first packet is enqueued.
Smart pointer class similar to boost::intrusive_ptr.
