PM76570: CALCULATED ROUND TRIP TIME INCORRECT

Web18 Nov 2012 · In TCP how is the time for a time out to happen determined? I was told it is randomly selected from an interval that doubles after each time out, but nothing I found on Google mentions anything about random selection and instead says it's calculated used Smoothed Round Trip Time after the first acknowledgment is received. Websrtt – Smoothed Round Trip Time – This estimate of response time is based on the observed traffic between the Nmap station and the remote device. This value is provided in microseconds. rttvar – Round Trip Time Variance – Network communication can be very unpredictable, and Nmap compensates for this uncertainty by creating a range of ...
