John,
In the DRS the receiver tries to estimate the bandwidthXdelay product of the
network and the congestion-control state of the sender, again using TCP
packet header information and Timestamps.
You it spoke to me on a bounding function and I did not understand what you
want to say with this.
It would like to know more details.
You it could explain me?
In the absence of timestamps, the receiver cannot directly measure the
RTT. The best it can do is to bound it by measuring the time between
two segments containing sequence numbers that are exactly one window
apart. This is described in detail in
