A class to count the number of lost packets.
void SetBit(uint32_t seqNum, bool val)
Set a sequence number to a given state.
void NotifyReceived(uint32_t seq)
Record a successfully received packet.
uint32_t m_lastMaxSeqNum
Last sequence number seen.
bool GetBit(uint32_t seqNum)
Check if a sequence number in the window has been received.
uint32_t m_lost
Lost packets counter.
void SetBitMapSize(uint16_t size)
Set the size of the window used to compute the packet loss.
uint8_t * m_receiveBitMap
Received packets in the window size.
uint16_t GetBitMapSize() const
Return the size of the window used to compute the packet loss.
uint32_t GetLost() const
Get the number of lost packets.
uint16_t m_bitMapSize
Window size.
