Assignment Week3 final
Suppose two TCP connections are present over some bottleneck link of rate R bps. Both connections have a huge file to send (in the same direction over the bottleneck link). The transmissions of the files start at the same time. What transmission rate would TCP like to give to each of the connections?
Wireshark Lab:
Carefully read the Wireshark Lab (TCP) available at textbook’s web site. Follow the instruction given and submit the answers to the following questions (questions 2, 3, 6 and 8 at the website)
What is the IP address of gaia.cs.umass.edu? On what port number is it sending and receiving TCP segments for this connection? 
What is the IP address and TCP port number used by your client computer (source) to transfer the file to gaia.cs.umass.edu? 
What is the sequence number of the TCP segment containing the HTTP POST command? Note that in order to find the POST command, you’ll need to dig into the packet content field at the bottom of the Ethereal window, looking for a segment with a “POST” within its DATA field. 
What is the length of each of the first six TCP segments?
Note:
Make sure that the Capture is not is the promiscuous mode. (The option in the packet capture window “Capture packets in promiscuous mode” should be unselected) 
It is suggested to make sure your browser’s cache is empty every time you start capturing packets. 
Also submit the capture file with “All packets” and a screenshot.
