Hello, I am working on a project in which I need to find the instantaneous RTT's and RTO's over a period of 20 Minutes of a TCP connection. I was able to get the RTT and RTO values from the t_rtttime and t_rxtcur variables in the tcp block structure but am not able to figure out the units of the values. I need to get both in same units. I think RTO's are in ticks. But am not very sure about RTT. Please could you help me with the same. I would really be grateful. Also I found that 1 TCP tick = 224 miliseconds. I just wanted to confim whether it is correct. I am using FreeBSD 4.9 Stable. I am sending a sample of the values I have collected. t_rtttime = 354397342, t_srtt = 68069, t_rxtcur = 1689 Waiting for your reply. Thanking you, Yours truly, Tanmay Ganacharya
