Assignment Problem: Network Performance Analysis
Purpose of the assessment (with ULO Mapping) This assignment assesses the following Unit Learning Outcomes; students should be able to demonstrate their achievements in them.
1) Discuss performance and deployment issues for networked applications;
2) Utilize 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 utilization to capture data from live network traffic. Through the labs, students have learned how to analyze 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 and a completed document file needs to be submitted.
Part 1:
From the (MIT lab Network), students need to chase and capture three websites in the table below (Table 1). Students have to analyze the performance for each website in regards of:
a) Load Distribution
b) Throughput Graph
c) Time Sequence Graph
d) Flow Graph
e) Window Scaling Graph
The performance analysis requires screenshots of the graphs and statistics generated by Wireshark and the discussion of those screenshots in detail.

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