1. List 3 different protocols that appear in the protocol column in the unfiltered packet-listing window.
A: The three different protocols that appear in the protocol column in the unfiltered packet-listing window are:
TCP
UDP
HTTP
2. How long did it take from when the HTTP GET message was sent until the HTTP OK reply was received?
A:
If we look at the frame section of the GET request we see that the time the packet arrived is
08:27:27.001732000
The same section for the HTTP OK shows an arrival time of 08:27:27.006338000
The difference of these 2 times gives .006338000- .001732000= 0.004606 seconds
3.What is the Internet address of the gaia.cs.umass.edu (also known as wwwnet.cs.umass.edu)?
A: If we look at the IP section of the GET request, the source and destination are
shown
The source is the local machine’s address and the destination is the web server’s
public
My (local machine’s) address = 192.168.0.110
IP address 128.119.245.12 = gaia.cs.umass.edu
