Topology
Objectives
Part 1: Use Ping to Document Network Latency
Part 2: Use Traceroute to Document Network Latency
Background / Scenario
To obtain realistic network latency statistics, this activity must be performed on a live network. Be sure to
check with your instructor for any local security restrictions against using the ping command on the network.
The purpose of this lab is to measure and evaluate network latency over time and during different periods of
the day to capture a representative sample of typical network activity. This will be accomplished by analyzing
the return delay from a distant computer with the ping command. Return delay times, measured in
milliseconds, will be summarized by computing the average latency (mean) and the range (maximum and
minimum) of the delay times.

Lab - Test Network Latency with Ping and Traceroute
Note: Because www.ripe.net and www.arin.net do not reply to ICMP requests, they cannot be used for this
lab.
Note: If the websites are resolved to IPv6 addresses, the option -4 can be used to resolve to IPv4 addresses
if desired. The command becomes ping -4 www.arin.net.

b. Using the ping command with the count option, you can send 25 echo requests to the destination as
illustrated below. Furthermore, it will create a text file with filename of arin.txt in the current directory. This
text file will contain the results of the echo requests.
C:\Users\User1> ping –n 25 www.lacnic.net > lacnic.txt

Note: The terminal remains blank until the command has finished, because the output has been redirected to
a text file, lacnic.txt, in this example. The > symbol is used to redirect the screen output to the file and
overwrite the file if it already exists. If appending more results to the file is desired, replace > with >> in the
command.
c. Repeat the ping command for the other websites.
C:\Users\User1> ping –n 25 www.afrinic.net > afrinic.txt
C:\Users\User1> ping –n 25 www.apnic.net > apnic.txt
Directory of C:\Users\User1

To see the results in the file created, use the more command at the command prompt.
C:\Users\User1> more lacnic.txt
Note: Press the Spacebar to display the rest of the file or press q to exit.
Record your results in the following table.
Step 1: Use the tracert command and record the output to text files.
Copy the following commands to create the traceroute files:

Reflection Questions
1. The tracert and ping results can provide important network latency information. What do you need to do if
you want an accurate baseline picture regarding network latency for your network?
Kita perlu melakukan analisis delay dengan cermat selama beberapa hari berturut-turut dan dalam
periode tertentu.
