A) (3 points) Consider a TCP connection already established and the RTO is calculated based on the Estimated Round Trip Time (ERTT) and the Deviation (DEV). Assume the following: - Initial ERTT =150ms, Initial DEV =40ms. - RTO is calculated as RTO =ERTT+4 DEV. - After each transmission, ERTT and DEV are updated as follows: - New ERTT =(6/8) Old ERTT +(2/8) SampleRTT. - New DEV =(3/4) Old DEV +(1/4) SampleRTT - New ERTT . iven RTT measurements for successive transmissions: 200ms,180ms. Determine the RTO ter each update. B) Using the graph below, show the complete timing segments diagram from A to B, knowing that A has a file of 800 bytes starting at initial sequence no of 240 , the segment size is 100 and B has a window stze of 400 bytes, and the 5in segment was lost. 1. (3 points) Show the sequence numbers, acknowledgment numbers, and the control flags when relevant to the segments exchanged between A and B, and actions taken to accommodate the lost segment
