Protect Oneself

Protect against burstiness and staleness

• Smooth out sending of data packets

  • use cwnd/rtt as rate to break up large bursts

• Use most recent successful window size

  • cwnd/2 if in slow start, cwnd-1 if in linear phase

• Quick detection/recovery from failed fast start

  • abort fast start upon packet loss
  • fall back to standard slow start
  • do not impose congestion control penalties
