CSCD 433/533 Lab 2 Network Measurement

Due: Jan 31st, 2017

Instructions

In this lab you will be going to some sites and performing some network tests to test various aspects of the Internet and your connection to the Internet. Also, to do some distance tests for packet delivery speeds

Task 1 - Speedtest for Your Connection

For this task, you will go to the Ookla Speedtest site and try out some of the speed and site quality tools.
Site URL is: Speedtest Site
From your home: Click on the Begin Test and report your results for Ping, Download and Upload results
Do this test twice and report both results.
1. From EWU: Do this test from EWU. Record your results.
2. From Home: Do this test from Home. Record your results
3. Compare results from home and EWU. Report which is faster? Compute a comparison, percentage or whatever you like. By how much faster?

Task 2 - Compare Results with Others

At the same site, Ookla Speedtest site, at bottom of screen, click on Speedtest Awards
1. Click on . What is the United States fastest ISP's speed and provider? Report the result
2. Click on several other countries of your choice and report their speed and provider.
3. Answer the question: Is the United States the fastest of the counties you sampled? If not, then who is faster?

Task 3 - Web Site Performance

Go to a site for testing Web Sites, Keycdn.com
URL: Keycdn.com
Enter EWU's web page, http://www.ewu.edu below in the URL box
Select the location to test from, New York is the first choice.then click Run.
1. Report on how long it took to load the whole site.
2. How many components do we have at EWU to our site?
3. What type of components take the longest to run?
4. Repeat the test from a different locations. Try Tokyo and Seattle. Report load time. Does it seem that distance makes a difference in web site load time?
5. Now, type in a more popular site any one you want and repeat the test. Report the same as EWU's results.

Task 4 - Run Ping around the world

In this test, you are simply going to ping sites around the world and construct a graph of distance verses ping speed. Do you recall how ping works? Ping sends a packet with an ICMP message in the packet, Echo Request. If the packet makes it to its destination, it get back an Echo Reply. You can time the response packets back. Useful for rough performance metrics.

1. Ping each site below. Run at the command level: $ ping site  Let it run about 15 pings. Report the min. avg. and max for each site
2. Look up the distance between the site and Spokane, WA. Record that.
3. Graph using excell or other program, distance vs. ping speed for the min. ping speed.
4. Answer the Questions
a. Is there a correlation between distance and ping time?
b. Which site was the most variable, greatest difference between min ping and max ping.?
c. Was there a significant jump in ping time for sites not in North America?
5. What happens if ping is not successful?

Sites to Ping
1. www.gonzaga.edu   Gonzaga
2. www.washington.edu    University of Washington
3. berkeley.edu    UC Berkeley
4. www.cam.ac.uk    University of Cambridge, England
5. www.usyd.edu.au    University of Sidney Australia
