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.
