Introduction
To ensure effective and continued functioning
of the network, management should be part of the
daily routine. Network management activities include
maintaining the quality of the services provided,
performance management, securing the network and
also analyzing the network to determine its
performance through analysis tools [12]. These
services apply to all the operating systems such as the
Linux, Microsoft System, and MAC among others. The
Graphical User Interface (GUI) is used is used in the
analysis of both the Windows operating systems and
the Linux version [5]. The open source packet checker
is the best-known graphical user interface and is found
in Windows operating systems. This interface is tasked
with the analysis of network protocol for every
captured packet, picking out the TCP stream through
traffic filter monitoring, and also the filter functionality
possession.

General statistics
Various analysis tools such as the Wireshark
and the Message Analyzer are used in analyzing the
network. However, the Wireshark is the world's most
common and preferred source packet analyzing tool
[1]. The analyzer is used in a variety of functions such
as the network and the communication protocol
analysis and troubleshooting. In this project, the data
to be analyzed will be captured from two websites;
http://iview.abc.net.au and
http://www.lightfm.com.au. The Wireshark analyzing
too will be used for the analysis. The data to be
analyzed will be accessed from home with an Ethernet
interface connection. The Wireshark tool will use the
HTTP and the web server of the two websites in the PC
for the capturing and analysis of the generated
packets. Moreover, the software will use the captured
data to determine the sequence graph, windows
scaling, load distribution and the throughput essential
in evaluating network performance.

Time of capture
Wireshark is composed of various features
including the time capture, time for the first and last
packet and the elapsed time [7]. The screenshot below
shows an opened Wireshark.

Both the IP address of the client and the
number sequence in the network are identified. To

establish a dependable Transmission Control Protocol
(TCP) session, the three-way handshake is most
refereed. This is made possible only when the HTTP
launches on the host web server. The initiation of the
three-way handshake by the Transmission Control
Protocol through the internet leads to the session
establishment between the host PC and the web
server [11]. Several websites within the host computer
may contain different active TCP sessions.
