iLAB OVERVIEW

Scenario/Summary

In this first week of the course, we are discussing the signals seen at Layer 1, the physical layer, of the OSI model. For wired media, such as a UTP cable used in a local area network or a fiber-optic cable used to interconnect local area networks inside of a building, the signal is not easily viewed with the tools a network manager would have access to, nor would such viewing aid him or her in diagnosing and correcting problems on the network. However, for the wireless signals that we are seeing used more and more, these are easily viewed by using a low-cost spectrum analyzer. In this iLab, we will look at the different types of spectrum analyzers, look at typical signals seen on them, and then use one of them to examine wireless signals.

This iLab is in two parts. In Part 1, you will learn how to use the tool required to conduct analysis such as this in the real world. In Part 2, you will watch a video that shows common wireless signals. The grade for Part 1 is based on your successful completion of a set of questions demonstrating that you understand what a spectrum analyzer is and what type of information it displays to the network manager. The grade for Part 2 is based on your ability to use what you learned in Part 1 to identify and classify common waveforms seen in typical wireless local area networks.

You are required to submit a lab report to the Week 1 Dropbox.

iLab 4: Outside Plant Installation (70 points)

Note!

Submit your assignment to the Dropbox, located at the top of this page.

(See the Syllabus section "Due Dates for Assignments & Exams" for due dates.)

iLAB OVERVIEW

Scenario/Summary

For this week's lab, you be looking at “Right of Way” issues that deal with outside plant installations in a “real” scenario.

You will be using the Right of Way manual developed by the city of Burleson, Texas to determine what requirements the local jurisdiction has in the case of a new installation of media and what rules you will need to follow to complete the installation project. In this example, a city street must be crossed to interconnect two buildings to each other. Therefore, the local jurisdiction does cover Right of Way issues.

Here is the scenario.

You are the network manager for the local school district. Due to growth in the city, one of the elementary schools has run out of classroom space. Across a city street from this elementary school, there is a church that is for sale. The school district is considering purchasing this church as a low-cost way to expand the space in the elementary school. The local-area networks in the two buildings will have to be connected to each other. Due to the school district's data-security policy, the connection must be made using wired media. To install this media, the city street between the two buildings must be crossed. This crossing will be underground. Here is the relationship of the two buildings.

etwork manager, you will have done a feasibility study and are now at the point of looking at vendors, timelines, and project specifics. You will first issue a request for proposal (RFP) to hire a firm to perform this work for the school district. To create this RFP, you must determine what the city's requirements are for this type of work. After reading the Right of Way Manual also found in Doc Sharing and the background information from the iLab content item this week, answer the questions in the lab report on the iLab page.

Vendors will respond to the RFP and you will rank their answers based on a criteria you decide is best for the project.

SECTION I: Using Wireshark, answer the questions below.

1. Show a screen shot of the frame where the SYN-ACK for TCP stream 0 appears. What frame is this in? ( 4 points)

Add in your screen shot here.

2. How long from the time the client issued the initial SYN for stream 0 did it take the server to answer with the SYN-ACK? (4 points)

Which method did you use? What was your calculation?

3. Notice that the client had to issue two initial SYNs as the first one did not elicit a response. In what frame is the first SYN that was issued? (4 points)

4. How long did it take the client to issue the ACK to the SYN-ACK for TCP stream 0? (4 points)

5. How long did it take the client to issue the first GET for stream 0 after the TCP 3-way handshake was completed? Add in a screen shot of this with the HTTP expanded so you can see information about the GET. (4 points)

6. Is this fast or slow? NOTE:What is fast or slow is not specifically discussed in the material for the week. Is a response in some ten-thousandths of a second is seen as fast “enough” according to DeVry? What do you think? Justify your answer. (2 points)

7. What is the window size sent by the client to the server in the first GET frame? Not the calculated window size using the window scaling factor, the window size value. Show a screen shot of where you found this answer.(4 points)

8. As the client receives data does the window size get smaller, stay the same, or get bigger?(4 points)

9. What do you conclude from this? Is the client being overloaded? Is it the source of any delays in the response seen by the user? ( 2 points)

10. Examine the stream of frames now displayed. Does either end show a smaller and smaller window size as the frames go back and forth? ( 2 points)

11. Examine the stream of frames are there any significant differences in the times during the back and forth between the client and the server? ( 2 points)

12. How many duplicate ACKs are there for stream index 0? What filter did you use to search for the dup acks? Show a screen shot of your filter and results for full credit.(4 points)

13. How many of these are between the client and the server? (4 points)

14. Does this indicate a problem in the network? Yes or no? How do you justify your answer? (4 points)

SECTION II: ( 10 points) Using the 100 Tips for Wireshark document from Laura Chappell, outline your favorite 5 tips and outline when and how you would use them to troubleshoot a network problem. Write at least 3 sentences on each tip you select to profile. Each outline is worth 2 points each.

SECTION III: Looking at security with wireshark. (10 points)

Write a short paragraph about what you see in this example. What does this tell you about password security in general? How does this profile what an unauthorized person using wireshark could capture?
