Question

In TCP, we have two consecutive segments. Assume that the sequence number of the first segment is 101. What is the sequence number of the next segment in each of the following cases? a. The first segment does not consume any sequence numbers. b. The first segment consumes 10 sequence numbers.

Answer 1

Answer:

Given that the sequence number of the first segment is 101.

• The first segment does not consume any sequence numbers that is no data is sent using the first segment Number of bytes of data sent=0.

• The sequence number of the next segment or the second segment is given by

Sequence number = Previous sequence number + number of bytes sent by previous segment = 101 + 0 = 101

• Therefore the sequence number of the second segment is 101
