Network Performance Analysis
Purpose of the assessment
This assignment assesses the following Unit Learning Outcomes; students should be able to demonstrate their achievements in them.
d) Discuss performance and deployment issues for networked applications;
e) Utilise appropriate industry tools and techniques to manage networked applications
Assignment Description
This assignment is designed 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. In the report, students need to focus on the effect of different browsing data on graphs, and justify the effect of it. Students need to complete the following tasks in two different networks, the tasks 1a and 1b need to perform in MIT lab Network, and the 2nd task needs to perform in either home or work-place network.
Task-1a
From the (MIT lab Network), students need to chase and capture data packets from
a) List 3 different protocols that appear in the protocol column in the unfiltered packet-listing window in. Support your answer with an appropriate screenshot from your computer.
b) How long did it take from when the HTTP GET message was sent until the HTTP OK reply was received? (By default, the value of the Time column in the packet-listing window is the amount of time, in seconds, since Wireshark tracing began. To display the Time field in time-of-day format, select the Wireshark View pull down menu, then select Time Display Format, then select Time-of-day.)
c) What is the Internet address? What is the Internet address of your computer? Support your answer with an appropriate screenshot from your computer.
Task - 1b
From the (MIT lab Network), students need to chase and capture data packets from three websites in the table below (Table 1). Students have to analyse the performance for each website in regards 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. Students are free to choose any website. Show your analysis using TCP Stream Graph and Time Sequences Graph.
