Introduction:
The main purpose of creating this report includes the comparison between the three websites
which is to be done in the task one whereas in task two the load distribution has been analyzed
along with the throughput, time sequence, flow graph and the windows scaling graph as well.
The wireshark packet capture has been enabled on the websites which are visited in order to
analyze the performance of the website along with finding the distribution of the load. After this
the port numbers as well as the synchronizing messages are also analyzed in order to find out the
flow of the data traffic inside the network. Besides this various kinds of filters are used in order
to analyze the transmission of the data. The sending and receiving of the data packets is
generally done by the IP addresses and the source ports. The data packets are analyzed in order
to measure the performance of the network. After the analysis is completed a general overview
of the load on the server is is provided along with the response time that is required for getting
the acknowledgement. Network administrators can use this wireshark for the purpose of
analyzing the performance of the network. Along with this the security problems as well as the
other problems can also be analyzed associated with learning about the various kind of protocols.
The contents of the packets captured from the network is examined and different media and
interface can be used for the capturing of the live data packets from the network.
Task 1:
In this section the major task is to investigate the website and analyze the http and the tcp packet.
The major three websites which have been analyzed in order to generate the load distribution,
throughput, time sequence, flow graph and the windows scaling graph. The three websites have
been listed below:

Load Distribution
The load distribution is generally used for the purpose of analyzing the load from the http packet
that is captured for the network. The analysis of the load distribution has been done by analyzing
the response time of the server along with the load on the server which is given as percentage.
Throughput Graph

3INFORMATION TECHNLOIGY
The figure which has been shown above is associated with depicting the throughput graph
generated from the packet captured for http://www.onlinenewspapers.com/australi.htm. The
graph is created based on the segment length and the time.
Time Sequence Graph

4INFORMATION TECHNLOIGY
After the throughput graph time sequence graph has been generated for the
http://www.onlinenewspapers.com/australi.htm in order to analyze the sequence number with
respect to the time. The TCP packet are used for the generation of the time sequence graph.
Flow Graph

5INFORMATION TECHNLOIGY
The flow graph is created in order to analyse the flow of the data packets between the client and
the server and it is also associate with showing the hops that are used for sending the message to
the destination address.
Window Scaling Graph
