https://www.cloudshark.org/captures/d55a037d8f84 Please Explain and provide screenshots Thank You Look at the TCP Window size value in the ACKnowledgements comingfrom the server back to the workstation for the transfer of thefile. (Hint: the key to answering this question is to lookfor 3 duplicate window size values, which signals/triggers theSlowstart protocol.) Fill in the table below for each ACKbetween packets 11 and 158. DO NOT provide a screenshot for thisquestion. Note: make this table as long as needed to show all of theACKs. At which packet number (see hint above) does TCP’sSlowstart phase end and when does TCP’s Collision Avoidance phasebegin (see hint above)? In the last part of the lab, you will calculate thethroughput of the upload of the file. Identify the FIRST transmitted packet that contains the upload ofAlice In Wonderland text. This packet goes from the workstation tothe server. It’s one of those segments that is labeled “[TCPsegment of a reassembled PDU]” in the info column. Look in thedetails panel (bottom, white section) of CloudShark for somethingthat looks like: 0010 05 8c 6f 58 40 00 80 06 f6 6b 82 cb 97 58 80 77  ..oX@….k…X.w 0020 f5 0c ce 62 00 50 9a 9f dc ba 1c 94 ad aa 50 10  …b.P……..P. 0030 40 b0 9a 40 00 00 50 4f 53 54 20 2f 65 74 68 65  @..@..POST /ethe 0040 72 65 61 6c 2d 6c 61 62 73 2f 6c 61 62 33 2d 31  real-labs/lab3-1 0050 2d 72 65 70 6c 79 2e 68 74 6d 20 48 54 54 50 2f  -reply.htm HTTP/ 0060 31 2e 31 0d 0a 48 6f 73 74 3a 20 67 61 69 61 2e  1.1..Host: gaia. 0070 63 73 2e 75 6d 61 73 73 2e 65 64 75 0d 0a 55 73  cs.umass.edu..Us 0080 65 72 2d 41 67 65 6e 74 3a 20 4d 6f 7a 69 6c 6c  er-Agent: Mozill . .

Provide ascreen shot for 8a and b together.
b.What time was this “FIRST” segment sent? Identify the LASTtransmitted packet. Look for the HTTP packet that has “POST/ethereal-labs/lab3-1-reply.htm HTTP/1.1 (text/plain)” in the INFOcolumn.
c.What is the SEQ number of this “LAST” segment? Look in theTransmission Control Protocol headers for the “Next Sequencenumber.” What is this value? Provide a screen shot for 8c and dtogether.
d.What time was this “LAST” segment sent? Using the answers from a-d, above, calculate the amount of datasent and amount of time it took to send the data. Show your work.Consider that useful bandwidth calculations are oftenrepresented in bits/second or Megabits/second. If your values arein bytes, you’ll need to multiply by 8 to get bits. To get Megabitsfrom bits, you should divide by 1,048,576 (since that’s the numberof bits in a Megabit).DO NOT provide a screen shot for this;just your calculations are sufficient. . . .
