TASK 1
Introduction
This is a report on analyzation of network packets using Wireshark. It involves capturing of
packets of three different websites. The packets are then analyzed through four different ways
and their results analyzed accordingly and compared. The packets are analyzed by load
distribution, graph , time sequence, flow graph and window scaling. The last section contains
analyzation a video streaming packet for five minutes then the results are analyzed.
Analysis of Web performance in wire shark.
1.Analysis for http://www.newspapers.com.au/
By load distribution.
Load distribution uses time period of the loading of every web requested content by the client as
a focal point of study. Depending on the network and internet performance the duration which
different contents take to load keeps on changing [6].
The load distribution graph here shows the optimum performance of analysis with hundred
percent score card.
By use of throughput graph.
Through put graphs works by checking the amount of bytes per a given duration of time usually
seconds or milliseconds in most cases. To be able to come up with the website performance we
calculate the number of packet loss from the graph to be able to deduce the efficiency of the site.

By use of time sequence graphs.
Time sequence graph of this website shows instability behavior of bytes with respect to time
change. The change however is regular forming even intervals in change of one and half units of
bytes.
