Equation 1.1 gives a formula for the end-to-end delay of sending one packet
of length L over N links of transmission rate R. Generalize this formula for sending P such packets back-to-back over the N links.
Consider the given data
N = Total number of links
R = Transmission rate
L = Packet length
P = packets that tramnsmit over the N link
The following is the formula of back-to-back delay of sending P packets, each of length L over N links of transmisson rate
first packet's delay but, consecutive packet's delay would be , because they are not at the beginnig. They are at the router just before the final host. When a packet comes to final destination, at the same time next packet come to the router previous packet left. Then formula would be . First term for the first packet and second term is for remaining packets.
Yes this is the correct formula,
N*L/R the first packet reaches the destination.
N*L/R +L/R the second packet reaches the destination.
N*L/R +L/R+L/R the third packet reaches the destination.
After N*L/R + (P-1)*L/R reaches the Pth packet the destination.
N*L/R + (P-1)*L/R = (N+P-1)*L/R
