Google says Round Trip Time

That doesn't answer my question (I know the abbreviation RTT). Therefore I'm
trying again:
I'm just wondering what the RTT *exactly* means. Where are the exact measuring
points located?
=> How are the RTT values exactly calculated? Which values are actually used
for?
=> What about the processing time between the inbound leg and the outbound leg
(transcoding, ...)?
Somebody else more knowledgeable then me will have to chime in here, but
my guess would be, that since TCP is stateful, it's the amount of time
that a RTCP packet taken to be acknowledged the recipient.
The measure points located would probably be each hop in the path, which
typically can be visualized with traceroute.
Similar to ping; the math behind it I would have no clue.
And again, just a guess.
Doug
