Key points:

• TCP connection establishment mechanism relies on the use of two flags SYN and ACK, and an initial sequence number, one from each direction
• SYN flag is turned on only for the very first message (i.e., connection request), while ACK is off
• The second message (connection confirmation) has SYN off and ACK flag on. All remaining messages has ACK on (and SYN off)

Problem. A process at host A wants to establish a TCP connection with another process at host B. Assuming that host A chooses to use 1628 as the initial sequence number, and host B chooses to use 3217 as the initial sequence number for this connection, show the segments involved with the connection establishment process. You must include the following information for each such segment: (1) sequence number, (2) acknowledgement number (if applicable), (3) the SYN flag bit status, and (4) the ACK flag bit status.
