Question:

If the values for RTT for the first exchange (SYN-SYN/ACK) were 300ms and 100ms for the subsequent exchanges, what would be the RTO at the moment connection is closed (assume TCP calculated RTO just before removing the state). According to the formulas: =(1)+ =(1)+|| =+4 Typical parameters: =1/8 =1/4 RTO_initial=3
