In Fig. 6-36 we saw that in addition to the 32-bit acknowledgement field, there is anACK bit in the fourth word. Does this really add anything? Why or why not?

A process on host 1 has been assigned port p, and a process on host 2 has beenassigned port q. Is it possible for there to be two or more TCP connections betweenthese two...

Datagram fragmentation and reassembly are handled by IP and are invisible to TCP.Does this mean that TCP does not have to worry about data arriving in the wrongorder?

What is the total size of the minimum TCP MTU, including TCP and IP overhead butnot including data link layer overhead?

Both UDP and TCP use port numbers to identify the destination entity when deliveringa message. Give two reasons why these protocols invented a new abstract ID (portnumber...

When during TCP congestion control, timeout occurs in 5th transition, then shall those packets be considered as received or shall be resent?Asking for if question asks fo...

If TCP RTT is currently 20 ms and following acknowledgement come in after 22,24 and 23 ms respectively. What is new RTT estimate ?28.52728.8220.8221.22

here TOTAL 2000 segments need to be sent, and after x RTT, it will send 2001 segments but for total we shall take count of addition of all the previous also na?

Please help, I am getting total number of transmission to get BACK TO 38 as 14 and NOT 15.after 14th, it would have became 38, so no need to consider 15th segment right?

Fragmentation is only done at the DATA part of the IP layer and NOT the IP header right?in above, 1st should be 920 instead of 940 as 20B of IP header shall not be counte...
