TCP srtt least count

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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).
