Suppose we have two hosts, A and B. Host A sent file with 3000 bits to B as one large message with following information: - Distance between both is 3 kilometers. - A and B connected by a direct link of R= 1 Mbps. - Imagine the propagation speed over the link is 2*105 meters/sec. Calculate the propagation delay. Considering that file is sent it continuously. How much time is needed to send the whole file (Ignore deroc and doueue delay) Let us imagine that we have just one packet that is planned to send it from A host to the B host. The transmission rate between the A host and the switch is R1 and between the switch and the B host is R2. If we consider that our switch uses store-and-forward packet switching, what is the total end-to-end delay to send a packet of length L (Ignore dproc, dqueue, and dprop delay)
