Assume that the packets are routed from source to destination over a single channel with two intermediate switches in a network system with one source (S) and one destination (D). Along with that, the system is set with the following crucial parameters: network having bandwidth of 1 MBps, message size of 1000 bytes has to be transmitted, assume packet switching technique is employed in the system, and each packet contains a header of 100 bytes. From among the below-given packet sizes, choose an ideal/optimal packet size for the aforementioned configuration in order to achieve the optimal performance? State your decision(s) by carefully assessing each of the possibilities listed: i) 5 packets; i) 10 packets; iii) 20 packets [3]
