Maximum Frame period
(b) Consider the simple network depicted in the figure Q3 shown below.
A —2mbps—S1—2mbps– S2—2mbps— D
Suppose a message that is 8Mb long that is to be sent from Host A to Host D with two
packet-switches in between. The data rates of each layer is given as in the Figure Q3. Ignore
propagation, queuing, and processing delays.
(i) Consider sending the message from A to D without message segmentation. How
long does it take to move the message from Host A to the first packet switch(S1)?
Assuming that each switch uses store-and-forward packet switching, what is the total
time to move the message from A to D?
