Given the following parameters: N= number of hops between two end systems L= message length in bits B=data rate in bps P=fixed packet size in bits H=overhead (header) in bits per packet The total end-to-end time delay for datagram switching is calculated using the formula T = (L2 * (2*P2 /B)/N) + (H-1)) * (P/B) What value of P, as a function of N, L, and H would minimize the end-to-end time delay?

QUESTION 1 "A single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link. Suppose that the packet length is L= 12000 bits, and that the link transmission rate along the link to router on the right is R = 1000 Mbps. What is the maximum number of packets per second that can be transmitted by the link (use a whole number)?"...
