    <h2 class="message-seq-title">Solution</h2>
    The red line is the value of the sstrash, when cwdn>=sstrash then the state switches to "congestion avoidance" and the growth is linear.
    When cwnd is reset to MSS the congestion event must have been severe (unless a mild congestion happened when cwnd=2*mss).
