I’m working through questions from computer networking top down approach and was hoping to get some clarity on the end-to-end delay calculation. At this stage we are not considering processing, transmission or propagation delay.

N = link L = packet length R = transmission rate

N = link
L = packet length 
R = transmission rate

The end-to-end Delay is N*L/R N*L/R (N links in series, using store-and-forward between the links).

The author asks to generalize the above formula for sending P packets over N links.

The solution I derived is (N*L/R)*P(N*L/R)*P. 

Is this a reasonable solution.?

 

PS. This is not home working.
