how to draw the segmentation for this question?

Quiz\#3 (spring 2019) Question one: Two applications (download manager, facebook) are running on a station. They are connected through two TCP sessions to two distant stations (Britain, USA). Each TCP session is given an ISN (7000,10000). Two messages of lengths (4.5KB,9.75KB) are sent through the two TCP sessions. Hence perform the following activities: a. Draw a schematic diagram for the two TCP sessions. b. Show how the message of each session is segmented. N.B: Assume MSS is equal to 3KB
