To study the operation of Ethernet and key concepts related to TCP/IP protocols by analyzing an Ethernet frame with a TCP packet. A specific network analyzer (many free- download versions available online) is to be used to capture network data frames. Conduct an online search for "network protocol analyzer". A large number of candidates will show up. Test and then select the one which works best for you - the minimum requirement is the ability to catch Ethernet data frames with OSI model layers details presented. 1. Complete the following Table 1:
Table 1: Protocol analyzer information
Name of the analyzer

2. Run the protocol analyzer and capture network traffic. Among the data frames captured, select one Ethernet frame that has an embedded TCP frame. This Ethernet data frame will be the focus of the subsequent steps.
3. Insert in the box below (you may enlarge it as needed) a screen shot of the protocol analyzer with at least one captured Ethernet frame expanded to show the IP packet and enclosed TCP header, i. e. the headers at Data link, Network, and Transport layers should be shown explicitly.
4. Regarding the Ethernet frame, complete the following Table 2:
