Ipv4 addresses are stored in host order in this class.
uint32_t GetSize() const
Returns the the size in bytes of the packet (including the zero-filled initial payload).
uint64_t GetUid() const
Returns the packet's Uid.
Ptr< const Packet > GetPacket() const
Get packet from entry.
void SetExpireTime(Time exp)
Set expire time.
Ipv4Address GetNextHop() const
Get next hop.
Ipv4Address GetSource() const
Get source address.
Time GetExpireTime() const
Get expire time.
Ipv4Address GetDestination() const
Get destination address.
Time m_errorBufferTimeout
The maximum period of time that a routing protocol is allowed to buffer a packet for,...
uint32_t m_maxLen
The maximum number of packets that we allow a routing protocol to buffer.
bool Enqueue(DsrErrorBuffEntry &entry)
Push entry in queue, if there is no entry with the same packet and destination address in queue.
void DropLink(DsrErrorBuffEntry en, std::string reason)
Notify that packet is dropped from queue by link error.
bool Dequeue(Ipv4Address dst, DsrErrorBuffEntry &entry)
Return first found (the earliest) entry for given destination.
bool Find(Ipv4Address dst)
Finds whether a packet with destination dst exists in the queue.
void DropPacketForErrLink(Ipv4Address source, Ipv4Address nextHop)
Remove all packets with the error link.
uint32_t GetSize()
Returns the number of entries in the queue.
std::vector< DsrErrorBuffEntry > m_errorBuffer
The send buffer to cache unsent packet.
void Drop(DsrErrorBuffEntry en, std::string reason)
Notify that packet is dropped from queue by timeout.
void Purge()
Remove all expired entries.
