Ipv4 addresses are stored in host order in this class.
Smart pointer class similar to boost::intrusive_ptr.
Control the scheduling of simulation events.
static Time Now()
Return the current simulation virtual time.
Simulation virtual time values and global simulation resolution.
Ipv4Address m_dst
Destination address.
Ptr< const Packet > m_packet
Data packet.
DsrSendBuffEntry(Ptr< const Packet > pa=nullptr, Ipv4Address d=Ipv4Address(), Time exp=Simulator::Now(), uint8_t p=0)
Construct DsrSendBuffEntry with the given parameters.
uint8_t m_protocol
The protocol number.
void SetDestination(Ipv4Address d)
Set destination address of entry.
void SetPacket(Ptr< const Packet > p)
Set pointer to entry's packet.
Time GetExpireTime() const
Get expire time for entry.
void SetProtocol(uint8_t p)
Set protocol value.
Ipv4Address GetDestination() const
Get destination address of entry.
Time m_expire
Expire time for queue entry.
uint8_t GetProtocol() const
Get protocol value.
void SetExpireTime(Time exp)
Set expire time for entry.
Ptr< const Packet > GetPacket() const
Get pointer to entry's packet.
bool operator==(const DsrSendBuffEntry &o) const
Compare send buffer entries.
void SetMaxQueueLen(uint32_t len)
Set the maximum queue length.
Time GetSendBufferTimeout() const
Return the entry lifetime in the queue.
uint32_t GetSize()
Number of entries.
bool Dequeue(Ipv4Address dst, DsrSendBuffEntry &entry)
Return first found (the earliest) entry for the given destination.
uint32_t GetMaxQueueLen() const
Return the maximum queue length.
void SetSendBufferTimeout(Time t)
Set the entry lifetime in the queue.
void Purge()
Remove all expired entries.
Time m_sendBufferTimeout
The maximum period of time that a routing protocol is allowed to buffer a packet for,...
std::vector< DsrSendBuffEntry > m_sendBuffer
The send buffer to cache unsent packet.
std::vector< DsrSendBuffEntry > & GetBuffer()
Return a pointer to the internal queue.
bool Enqueue(DsrSendBuffEntry &entry)
Push entry in queue, if there is no entry with the same packet and destination address in queue.
bool Find(Ipv4Address dst)
Check if a packet with destination dst exists in the queue.
uint32_t m_maxLen
The maximum number of packets that we allow a routing protocol to buffer.
void Drop(DsrSendBuffEntry en, std::string reason)
Notify that packet is dropped from queue by timeout.
void DropPacketWithDst(Ipv4Address dst)
Remove all packets with destination IP address dst.
DsrSendBuffer()
Default constructor.
Time Now()
create an ns3::Time instance which contains the current simulation time.
Every class exported by the ns3 library is enclosed in the ns3 namespace.
