When closing a TCP connection, why is the two-segment-lifetime timeout not necessary on the transition from LAST_ACK to CLOSED?

Is this the right answer or the wrong answer? Assume that the most recent SampleRTT for a TCP connection is one second. The TimeoutInterval setting for the connection must now be set to a value that is greater than one second.

Is it usual or unusual for TCP SYN and ACK segment to carry data during the three-way handshake connection- oriented process. Explain why.

The acknowledgment number in a TCP segment is the sequence number of what

If the destination port field of a TCP segment contains the binary number 0000000001010000 what protocol is being used?

Upon seeing a wireshark recording of a conversation. How exactly would one go about determining what the demultiplexing key for a TCP stream is?

An HTTP client opens a TCP connection using an initial sequence number (ISN) of 14,534 and the ephemeral port number of 59,100. The server opens the connection with an ISN of 21,732. Show the three TCP segments during the connection establishment if the client defines the rwnd of 4000 and the server defines the rwnd of 5000. Ignore the calculation of the checksum field.

Suppose that a TCP source uses a=0.2 and b=0.25. Further assume that this TCP source has just received three ACKs for which it calculated the following SampleRTT values: 24ms, 31ms, 28ms. What are the latest EstimatedRTT and DevRTT values at this TCP source? Assume that the starting values of EstimatedRTT and DevRTT are 30ms and 3ms, respectively. Also, what is the latest TimeOutInterval at this TCP source? Two-digit precision is sufficient in your calculations.

What TCP fields are used in TCPs sliding window algorithm?
