Cwnd Congestion Start Mss Tcp Control Slow Beginning

Front TCP: Congestion Control: Slow Start
Back At the beginning of the connection (or after a timeout)

- cwnd = 1 MSS
- cwnd is doubled per RTT (exponential)
- Procedure: For each ACK received
Cwnd by 1 MSS
increased
- As soon as ssthresh (slow start threshold) has been reached, congestion avoidance is changed
