You would like to send a 2100-byte chunk of data uslng TCP from Computer A to Computer B. TCPsegments are carrled In IP datagrams with a 20-byte header. IP datagrams are carrled In a data link framewith a 10-byte header. The maxlmum segment slze for TCP Is 800 bytes. The physlcal layer protocol cansupport a data rate of 1 Mbps. Assume a total round-trip time of 10 ms between the sender and therecelver.How many frames will need to be sent from Computer A to Computer B? What Is the size of eachTCP segment? Show your work

Consider transferring an enormous file of L bytes from host A to host B. Assume an MSS of 1460 bytes.a. What is the maximum value of L such that TCP sequence numbers are not exhausted? Recall that the TCP sequence number field has four bytes.b. For the L you obtain in (a), find how long it takes to transmit the file Assume that a total of 66 bytes of transport, network, and data-link header are added to each segment before the resulting packet is sent out over at 10 Mbps link. Ignore flow control and congestion control so A can pump out the segments back to back and continuously.
Consider transferring an enormous file of L bytes from Host A to Host B. Assume an MSS of 536 bytes.a. What is the maximum value of L such that TCP sequence numbers are not exhausted? Recall that the TCP sequence number field has 4 bytes.b. For the L you obtain in (a), find how long it takes to transmit the file. Assume that a total of 66 bytes of transport, network, and data-link header are added to each segment before the resulting packet is sent out over a 155 Mbps link. Ignore flow control and congestion control so A can pump out the segments back to back and continuously.
Suppose that MSS = 2000 bytes, TCP is in AIMD, and its window size is currently W = 4. Assume the slow start threshold is infinity. a) After receiving 4 non-duplicate ACKs, what is TCP’s window size? Explain your result by showing the relevant formulas. b) After these 4 ACKs, packet loss is detected through a timeout. What is TCP’s window in bytes immediately after the loss? What is the slow start threshold in bytes? c) Specify the window size for each of the five RTTs (one value of W per RTT) following the loss in part b. No additional packet loss occurs.
True or false? Suppose Host A sends one segment with sequence number 38 and 4 bytes of data over a TCP connection to Host B. In this same segment the acknowledgment number is necessarily 42.
True or false? With nonpersistent connections between browser and origin server, it is possible for a single TCP segment to carry two distinct HTTP request messages.
Suppose the sequence number field on a TCP packet is 46005. The packet carries 102 bytes of (application-layer) data. The TCP header size on this packet is 20 bytes. (a) What is the sequence number of the last application byte contained in the packet above? (b) What is the value of the acknowledgment number field on the ACK that the receiver generates for the packet above? (c) Do you have sufficient information in this question to determine the value of the sequence number field of the ACK packet that the receiver generates for the packet above? If so, what is the sequence number? If not, why not? (d) If the size of the TCP header were larger (e.g., 24 bytes, due to additional TCP options), would your answers to parts (a)–(c) change? Why or why not?
