Consider the following TCP state transition diagram. Give the appropriate timing diagrams (see Figures 3.31, 3.34 through 3.37 for examples) for the state transitions indicated in Questions 1-8.

1. CLOSEDSYN_SENTCLOSED

2. CLOSEDLISTENCLOSED

3. CLOSEDLISTENSYN_RCVDESTABLISHED

4. CLOSEDSYN_SENTESTABLISHED

5. ESTABLISHEDFIN_WAIT_1CLOSINGTIME_WAITCLOSED

6. ESTABLSIHEDFIN_WAIT_1FIN_WAIT_2TIME_WAITCLOSED

7. ESTABLISHEDFIN_WAIT_1TIME_WAITCLOSED

8. ESTABLISHEDCLOSE_WAITLAST_ACKCLOSED
