Web40E. Suppose the round-trip propagation delay for Ethernet is 46.4 μs. This yields a minimum packet size of 512 bits (464 bits corresponding to propagation delay +48 bits of jam signal). (a) What happens to the minimum packet size if the delay time is held constant and the signaling rate rises to 100 Mbps? In telecommunications, round-trip delay (RTD) or round-trip time (RTT) is the amount of time it takes for a signal to be sent plus the amount of time it takes for acknowledgement of that signal having been received. This time delay includes propagation times for the paths between the two communication … See more Round-trip delay and bandwidth are independent of each other.
