Congestion control abstract class.
Reno congestion control algorithm.
virtual void IncreaseWindow(Ptr< TcpSocketState > tcb, uint32_t segmentsAcked)
Congestion avoidance algorithm implementation.
virtual uint32_t GetSsThresh(Ptr< const TcpSocketState > tcb, uint32_t bytesInFlight)
Get the slow start threshold after a loss event.
std::string GetName() const
Get the name of the congestion control algorithm.
virtual uint32_t SlowStart(Ptr< TcpSocketState > tcb, uint32_t segmentsAcked)
Slow start phase handler.
virtual void CongestionAvoidance(Ptr< TcpSocketState > tcb, uint32_t segmentsAcked)
Congestion avoidance phase handler.
uint32_t m_cWndCnt
Linear increase counter.
virtual Ptr< TcpCongestionOps > Fork()
