Extension If an extension of time to submit work is required, a Special Consideration Application must be submitted directly to the Schools Administration Officer, in Melbourne on Level 6 or in Sydney on Level 7. You must submit this application three working days prior to the due date of the assessment. Further information is available at: procedures-and-guidelines/specialconsiderationdeferment
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. Students should make themselves familiar with the full policy and procedure available at: procedures-and-guidelines/Plagiarism-Academic-Misconduct-Policy- Procedure.
Assignment #02 Description
This assignment is designed to develop students analytical skills in addition to Wireshark utilisation to capture data from live network traffic. Through the laboratories, students have learned how to analyze HTTP packets, TCP packets streams, and 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. In a report, students need to focus on human-centered design as this is an approach to interactive systems development that aims to make systems usable and useful by focusing on the users, their needs and requirements, and by applying human factors/ergonomics, usability knowledge, and techniques.
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 with respect to:
? Load Distribution
? Throughput Graph
? Time Sequence Graph
? Flow Graph (Both general and TCP flow)
? Window Scaling Graph
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, ) Students are free to choose any website. Show your analysis using TCP Stream Graph and Time Sequences Graph.
Websites Performance Parameters
o Load Distribution o Throughput graph and o Time Sequence graph
o Flow graph (Both general and TCP flow)
o Window scaling graph
Table 1: Websites, analytical tools/performance parameters
NB: You can also demonstrate other statistics that you find to be significant for analysing this network traffic.
