Hello
I have been taking a look at the timestamp feature in RFC 1323.
My question is how are the TSval and TSecr fields represented in the current
implementation of linux, e.g. that is the resolution of the timers.
Is the format simply timeval.tv_sec from the time.h or is timeval.tv_usec
also mixed into the timestamp. (If someone would point to where in the code
this is defined)
Another question, as I understand the RFC, the timestamp are only relevant
to the box generating them. Are TCP implementation different in how the
TSval data is represented?
Is it possible to make use of the timestamp in an intermediate box, e.g.
estimating RTT in a box that a TCP connection passes?
I someone has the time to answer these question, it would be great.
with regards
r.harper
