Academic Misconduct

Academic Misconduct is a serious offence. Depending on the seriousness of the case, penalties can vary from a written warning or zero marks to exclusion from the course or rescinding the degree.

Assignment #02 Description

This assignment is design to develop student’s analytical skills in addition to Wireshark

utilisation to capture data from live network traffic. Through the labs, students have

learned how to analyse HTTP packets, TCP packets streams, audio streaming with TCP.

Students have learned to identify the performance parameters such as load distribution,

throughput graph, time sequence graph, flow graph and window scaling graph.

Overview and General Instructions of Assignment

Students need to use captured Wireshark data to explain the performance of the distributed

system behind the given web system.

Task - 1

From the (MIT lab Network), students need to chase and capture three websites in the table

below (Table 1). Students have to analyse the performance for each website in regards of:

 Load Distribution

 Throughput Graph

 Time Sequence Graph

 Flow Graph

 Window Scaling Graph

The analysis of the performance requires screenshots of the graphs and statistics

generated by Wireshark and the discussion of those screenshots in detail.

Table 1: Websites, analytical tools/performance parameters

Note: You can also demonstrate other statistics that you find to be significant for analyzing this network

Task - 2

Investigate streaming audio delivery over TCP by listening to Internet live radio and capturing

the transmitted packets. From a second network (Home, work, etc.), students have to chase

and capture one more website which has an audio stream (such as radio stations, e.g

http://www.abc.net.au/radio/listen-online ). Listen to the audio stream for at least five

minutes to capture enough packets for analysis. Students are free to choose any website.

Show your performance analysis using Throughput Graph and Time Sequences Graph.

Screenshots of the graphs need to be provided and the performance shown in the graph must

be discussed in detail
