ECSE 414, Lecture 8 22 Question Suppose Host A sends two TCP segments back to back to Host B over a TCP connection. The first packet has sequence number 90; the second has sequence number 110. How much data is in the first packet? Suppose that the first segment is lost but the second segment arrives at B. What will be the ACK number in the response sent from B to A? The receiver will ACK 90 since this is the next byte number it is expecting. 2010 Michael Rabbat

The first packet has sequence number 90; the second has sequence number 110. • How much data is in the first packet? • 110 – 90 = 20 bytes • Suppose that the first segment is lost but the second segment arrives at B. What will be the ACK number in the response sent from B to A? • The receiver will ACK 90 since this is the next byte number it is expecting. 2010 Michael Rabbat...
