In Figure 6-36 (page 557) we saw that in addition to the 32-bit acknowledgment field, there is an ACK bit in the fourth word. Does this really add anything to the TCP header? Why or why not?

You should read up on the topic of TCP and UDP to learn the distinctions between the two.

in a TCP message. What can one infer from a psh flag being set? How would one determine what caused it?

Is this statement true or false? Let's say for the sake of simplicity that a TCP connection's most recent SampleRTT is one second. The connection must be kept open if the current TimeoutInterval value is larger than one second.

TCP is a sliding window protocol. This means... а. the TCP retransmission timer slides up as ACKS are received. O b. there can be more than one segment "in flight" (sent but no ACK has been received) at a time. с. there can only be one segment outstanding (sent but no ACK has been received) at at time.

The following is a TCP (tranmission control protocol) header.  How do I read it?  What does each bit mean? c62800163d36b20c05087f6e7002ffff7bb70000

Since TCP uses sequence numbers for the data it is sending, there is no need to include the port in the TCP header. Select one: o True O False

Suppose you are hired to design a reliable byte-stream protocol that uses a sliding window (like TCP). This protocol will run over a 50-Mbps network, the RTT of the network is 80 ms and the maximum segment lifetime is 60 seconds. How many bits would you include in the Advertised Window and Sequence Num fields of your protocol header?

How does the TCP protocol prevent sequence numbers from looping back on themselves?
