Assignment #02 Description

This assignment is to 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 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 report, students need to focus on the effect of different browsing data on graphs, and justify the effect of it. Task-1a From the (MIT lab Network), students need to chase and capture data packets from http://gaia.cs.umass.edu/wireshark-labs/INTRO-wireshark-file1.html

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 of the gaia.cs.umass.edu? 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 of:

 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 http://www.radioau.net/ Students are free to choose any website. Show your analysis using TCP Stream Graph and Time Sequences Graph.
