Hi All, After going through the TCP code in linux kernel it seems that TCP in linux stores srtt in milliseconds and it is inflated by a factor of 8. Does this means that TCP in linux can measure any rtt which is greater than 125 microseconds? The code will store a value of 1 for srtt variable when the rtt is 125 micro seconds (125 microsecond * 8 = 1 millisecond). Saurabh -- Kernelnewbies: Help each other learn about the Linux kernel.
