Question: Question 4 . The end - to - end delay of sending one packet of length L over N links of transmission rate R is

Question 4.The end-to-end delay of sending one packet of length L over N links of transmission rate R is given by the formula NL/R.
A. Generalize the above formula for sending P such packets back-to-back over the N links.
B. If the transmission rate of first link is R/2 but all the remaining N-1 links is R, derive a formula to calculate end-to-end delay of sending one packet of length L over these N links.
C. If the transmission rate of first link is 2R but all the remaining N-1 links is R, derive a formula to calculate end-to-end delay of sending one packet of length L over these N links.
