Comprehensive Network Performance Analysis: Wireshark and TCP Analysis

This assignment provides a detailed analysis of network performance using the Wireshark packet analyzer. It begins with an introduction to network performance metrics and the Wireshark tool, followed by an analysis of three websites, examining load distribution, throughput graphs, Windows scaling, time sequence graphs, and flow graphs for each. The assignment then investigates audio streaming performance, specifically focusing on live radio, by analyzing throughput and time sequence graphs. The analysis covers identifying IP addresses, capturing TCP streams, and interpreting various graphs to understand network behavior and identify potential bottlenecks or performance issues. The conclusion summarizes the key findings and emphasizes the importance of Wireshark in maintaining service quality and understanding network link usage. References to relevant literature are also included.

Network Performance Analysis

INTRODUCTION
Network performance can be refereed as a way to measure the quality of services where
actions performed in the system (Narayana and et.al., 2016). It mainly investigates the network
link usage at different level by using different tool to determine the accurate statistically derived
an accounting bandwidth in different patterns.
This documentation will discuss about time sequence graph, load distribution, throughput
graph and flow graph with the help of Wireshark tool. Furthermore, it will analyse the output of
audio streaming website for network performance.
TASK 1
Discussion about three website performance to analyse the different parameters:
Load Distribution
It is based on the load process distribution that help for scheduling with distribute load of
system among resources or in other words it focuses on distributing load of a website/system
among available resources. It helps for improving the overall system performance and maximise
the utilisation resources by maximising speed, utilising whole capacity and by ensuring that no
one server is overloaded (Eisenbud and et.al., 2016).
Throughput graph
It will help in understanding amount of throughput on the services at the time of load test
scenario. It can be measured in the form of megabytes which shows the collection of information
or data that receive from server at second. This graph also helps in analysing the in which
through put affects transaction performance.
Time sequence graph
This type of graph is mainly representing the data stream over time because data
streaming is moving in one direction and representing the sequence number to send data in the
form of bytes. This graph helps in showing all the general activities or events that are happening
at the time of connection.

Flow graph
In Wireshark, it is mainly used for creating the column-based data that can summaries the
flow of information.
Window Scaling graph
Windows scaling graph applicable to show the actual size of the receiving window
including scaling factor. In other words this graph also helps in explaining the way receiver can
handle the data received from the website.
Wireshark:
It is an open source and free packet analyser platform that can be used for system or
network trouble shooting, communication protocol development, software etc. It can be used as a
cross platform by using Qt widget toolkit and also considered the current release for
implementing its specific user interface (Sanders, 2017). It mainly runs on different platforms
such as MacOS, Linux and windows etc. It also has integrated sorting, graphical front end and
filtering option. It allows its users to put their network interface controllers in promiscuous
mode, so that users will check all the visiblity traffic on that particular interface. It also includes
unicast traffic is not directly send to network interface controller's MAC address.

Website-1 http://www.onlinenewspapers.com/australi.htm
First of all, it has been determined that Internet protocol address of the website: 52.23.105.176
and then with the help of Wireshark, TCP stream, HTTP protocol can be determined as it is used
to capture and analyse the data where how much packet transmitted from other destination.
Capture throughput graph

Description:
This graph is mainly representing throughput graph of online newspapers website. It can
be calculating in terms of Average throughput(bytes) and segment length etc. It can be shown the
highest throughput between 2.15 to 3.20 intervals.

Website-2 www. Cbsinteractive.com.au
First of all, it has been determined that Internet protocol address of the website: 35.244.220.208
and then with the help of wireshark, TCP stream, HTTP protocol can be determined as it is used
to capture and analyse the data where how much packet transmitted from other destination.
Capture throughput graph
Description:
