Networking Analysis

This report provides a detailed analysis of networking using protocol analysers to gather information about the network based on the type of packets and protocols being investigated. It covers the investigation of various websites, including their key protocols, load distribution, throughput graph, time sequence graphs, flow graph, and windows scaling graph. The report also explores the live streaming delivery of audio over TCP and includes analysis with TCP stream graphs and TCP sequence graphs.

Summary
The purpose of this report is to use protocol analysers to obtain information about the network
based on the type of packets and protocols being investigated. First the report investigates the url
going by http://gaia.cs.umass.edu/wireshark-labs/INTRO-wireshark-file1.html and then lists
the three key protocols used in facilitating the communication. Along with that, the time it
takes to receive HTTP OK is also given and the time field is displayed in time to day format.
In answering this, the appropriate screenshots are also provided as well as IP address of
website and that of client. Going forward the report fetches the Load Distribution, throughput
graph, time sequence graphs (Stevens and tcptrace), flow graph and windows scaling graph
after capturing the packets of the three websites, - https://www.sbs.com.au/news/,
https://www.amazon.com.au and http://howeverythingworks.org/. Analysis of these websites
are done on devices connected to the university network. Thereafter the report proceeds to
investigate the live streaming delivery of audio over TCP by listening to live internet sourced
radio and the packets are captured. For this audio streaming websites are chased with devices
connected to the home network. The website chosen is http://www.radioau.net/ and the
analysis incudes investigation with TCP stream graphs and TCP sequence graphs.

Introduction
The following report is all about using protocol analysers for obtaining information about the
network based on the type of packets and protocols being investigated. The report begins by
investigating the url that goes by http://gaia.cs.umass.edu/wireshark-labs/INTRO-wireshark-
file1.html and then lists the three key protocols used in facilitating the communication.
Along with that, the time it takes to receive HTTP OK is also given and the time field is
displayed in time to day format. In answering this, the appropriate screenshots are also
provided as well as IP address of website and that of client. Going forward the report
fetches the Load Distribution, throughput graph, time sequence graphs (Stevens and
tcptrace), flow graph and windows scaling graph after capturing the packets of the three
websites, - https://www.sbs.com.au/news/, https://www.amazon.com.au and
http://howeverythingworks.org/. Analysis of these websites are done on devices connected
to the university network. Thereafter the report proceeds to investigate the live streaming
delivery of audio over TCP by listening to live internet sourced radio and the packets are
captured. For this audio streaming websites are chased with devices connected to the home
network. The website chosen is http://www.radioau.net/ and the analysis incudes
investigation with TCP stream graphs and TCP sequence graphs.

Wireshark Packet Capture
The following is the packet capture and analysis of the URL
http://gaia.cs.umass.edu/wireshark-labs/INTRO-wireshark-file1.html. Here the three major
protocols used are getting identified. Also mentioned is the time taken to obtain HTTP OK.
Then the Time field is formatted to time of day.
As per the above diagram, the packets get listed by the protocol analyser Wireshark
when chasing websites and urls. The duration of packet transfers are mentioned in the time
field. Also given are source and destination IP addresses.

4NETWORKING ANALYSIS
Three key protocols to have been used in ensuring the communication are TLSv1.2, TCP and UDP
protocols.
Time till OK as can be known by comparing the first two packets - .00030900 of the above diagram.

In conclusion, the above report successfully analyses networks with the help of protocol
analysers for obtaining information about the network based on the type of packets and protocols
being investigated. The report begins by investigating the url that goes by
http://gaia.cs.umass.edu/wireshark-labs/INTRO-wireshark-file1.html and then lists the three
key protocols used in facilitating the communication. Along with that, the time it takes to
receive HTTP OK is also given and the time field is displayed in time to day format. In
answering this, the appropriate screenshots are also provided as well as IP address of
website and that of client. Going forward the report fetches the Load Distribution,
throughput graph, time sequence graphs (Stevens and tcptrace), flow graph and windows
scaling graph after capturing the packets of the three websites, -
https://www.sbs.com.au/news/, https://www.amazon.com.au and
http://howeverythingworks.org/. Analysis of these websites are done on devices connected
to the university network. Thereafter the report proceeds to investigate the live streaming
delivery of audio over TCP by listening to live internet sourced radio and the packets are
captured. For this audio streaming websites are chased with devices connected to the home

investigation with TCP stream graphs and TCP sequence graphs.
