Computer A uses HDLC with Go-back-N ARQ to send 3 Mbytes file to computer B. Given each frame
carries 40Kbytes data. How long does it take to send the whole file (the total time taken from A sending
the first bit of the file until A receiving the last acknowledgment)? Given that the transmission rate of
the link is 100Mbps and the propagation time between A and B is 10ms. Assume the maximum
allowable window size is used, no data or control frame is lost or damaged. Ignore the overhead due
to header and trailer.
