Suppose there is exactly one packet switch between a sending host and a receiving host. The transmission rates between the sending host and the switch and between the switch and the receiving host are R1 and R2, respectively.
Assuming that the switch uses store-and-forward packet switching, what is the total end-to-end delay to send a packet of length L? (Ignore queuing, propagation delay, and processing delay.)
Consider the data:
R1= Transmission rates between the sending host and the switch
R2= Transmission rates between the switch and the receiving host
L= Packet of length
Therefore, total end-to-end delay to send a packet of length L=L/R1+L/R2
