30 km A B Problems: B. Now suppose A wants to send a 5 MB file to B as a sequence of packets. As above, assume packet size is 500 bytes. To prevent any packet loss, when A sends a packet to B, B responds with a packet of size 50 bytes as an acknowledgement to A that it has received the packet successfully. Only after receiving the acknowledgement, A sends the next packet. Assuming no losses, how long will it take for A to send the entire file to B? The link bandwidth is 4Mbps(4 million bits per sec).
