Member Function Documentation

virtual TCPStateVariables* TCPNoCongestionControl::createStateVariables (   )  [inline, protected, virtual]

Create and return a TCPNoCongestionControlStateVariables object. Implements TCPAlgorithm. { return new TCPNoCongestionControlStateVariables(); }

void TCPNoCongestionControl::initialize (   )  [virtual]

Initialize state vars Reimplemented from TCPBaseAlg. { TCPBaseAlg::initialize(); // set congestion window to a practically infinite value state->snd_cwnd = 0x7fffffff; }

void TCPNoCongestionControl::processRexmitTimer (  TCPEventCode &  event  )  [protected, virtual]

Redefine what should happen on retransmission Reimplemented from TCPBaseAlg. { TCPBaseAlg::processRexmitTimer(event); if (event==TCP_E_ABORT) return; // Tahoe-style retransmission: only one segment conn->retransmitOneSegment(); }

void TCPNoCongestionControl::receivedDataAck (  uint32  firstSeqAcked  )  [virtual]

Redefine what should happen when data got acked, to add congestion window management Reimplemented from TCPBaseAlg. { TCPBaseAlg::receivedDataAck(firstSeqAcked); // ack may have freed up some room in the window, try sending sendData(); }
