Prepared by: Dr S M Farhad Moderated by: Dr Javed Baloch March, 2019 Page 1 of 5 BN208 Networked Applications Assignment 2 Page 2 of 4 Assignment #02 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 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 Prepared by: Dr S M Farhad Moderated by: Dr Javed Baloch March, 2019 Page 2 of 5 BN208 Networked Applications Assignment 2 Websites https://www.sbs.com.au/news/ https://www.amazon.com.au Page 3 of 4 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 http://howeverythingworks.org/ Table 1: Websites, analytical tools/performance parameters 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. NB: You can also demonstrate other statistics that you find to be significant for analysing this network traffic.

TCP Stream Graphs and Time Sequence Graphs
Task 2:
Explain briefly the output of the graphs
The website https://radioau.net/#raw-fm is a conceptual website developed with the appropriately
outlined streams and time sequence. The output of the graphs can be explained with reference to
the TCP stream graphs and the Time Sequence graphs.
TCP Stream Graph
The TCP stream graph of the website is aligned with the frequency to allow for global access
throughout the internet. Some of the TCP Stream graph output conducted on the website includes
throughput graph, time sequence, window scaling and round-trip time.
The Throughput
The throughput of the website showcased its throughput of the connection and outlined some of
its instabilities. The throughput of the https://radioau.net/#raw-fm website is limited to certain
conceptual alterations while disregarding some of the factors that result to this condition. From the
graph, it is clear that the throughput for the website is not stable and that it varies from 20,000 byte
per second to 1000 byte per second. This can be caused by unstable file transfer between the
connection hosts overlay towards the current state. Also, the instability might be caused by
application reserialization between the communication and connection ports. There is stability
from 5000 byte per second to zero byte per second. Moreover, there is lower throughput between
200 seconds to 700 seconds of connectivity. This changes from zero seconds to 200 seconds of
connectivity, whereby higher throughputs are witnessed.

Round Trip Time
Round trips provide an outlook at the performance of a connection. Round trip shows
acknowledgement of certain instabilities within a long period of time. Unlike the previous
throughput graph which showed instability difference over a short period of time, round trip graphs
show instability occurrence but over a long period of time, since the occurrences are not often
realized. From the website, there exists more stable round trip time instances than the few numbers
of unstable round-trip times in the connection. There also exists a small window of conceptual
alignment between the two aspects overall. The small instances of instability of the round-trip
times are caused with the changing protocol between the connection any time a party makes
changes to the connection.
The Window Scaling Graph
The window scaling graph basically indicates a receiver’s ability to process the data outlined to it.
In large scale overviews, concepts such as the performance of the connection is considered and
completely outlined with the appropriate ways possible.
The window scaling graph of the website shows that instability is caused by one of the sides from
the connection. This can be as a result of server or client difference hence, might indica...
