OBJECTIVES
The purpose of this homework is to give you experience on network analyzing with
Wireshark tool. You will meet different protocol types, and performance metrics such as Throughput,
Round Trip Time (RTT) and Window Size. Moreover, various TCP types such as TCP-RENO, TCP-VEGAS
and TCP-WESTWOOD will be compared according to them.
In order to observe clear results in following questions, background traffic should be dense.
Therefore, assign a wireless network in public areas such as cafes.
QUESTIONS
You are expected to answer the following questions by enhancing Wireshark screenshots:
1. (20 Points) Protocol analysis:
a. How many different traffic protocols do you capture in Wireshark? Please give them
in a list.
b. What are the specific protocol numbers of transport layer protocols (TCP, UDP, and
ICMP)? Show them in packet headers seen in Wireshark.
2. (30 Points) Throughput and RTT statistics:
a. Build a performance graph includes TCP and UDP packets received from your
networking device by defining specific filter equation.
3. (50 Points) TCP version analysis:
In your LINUX system; in order to check TCP congestion control version, you should run the
following command:
sysctl net.ipv4.tcp_available_congestion_control
Pay attention to the TCP version!: reno, vegas, westwood.
If any of them are not seen in the list, load related module with following command:
/sbin/modprobe tcp_vegas
In order to check the current TCP version of the system and change it, you should run the
following commands:
sysctl net.ipv4.tcp_congestion_control
sysctl –w net.ipv4.tcp_congestion_control=vegas
For three different TCP version; TCP-RENO, TCP-VEGAS, TCP-WESTWOOD:
You are asked to run Skype video call between different networking devices such as
computer and mobile phone. Build performance graphics to show differences between these
TCP versions. What do you expect to observe? What do you observe? You are expected to
give your answers with detailed commands.
