Network Design Report: Application Performance and Simulation Analysis

This report provides a comprehensive analysis of network design and simulation, focusing on achieving optimal application performance. The report begins by emphasizing the importance of identifying network requirements through methods like questionnaires distributed to stakeholders. It explores various operating systems and their suitability, with a preference for Microsoft Windows due to its user-friendliness. The report discusses the necessity of multiple hubs and routers for efficient data handling and the use of switches for managing data packets. The design section includes a demonstration using simulators, detailing application sets and their performance requirements, such as capacity, reliability, and delay for various software categories including word processing, database, and multimedia applications. The report concludes by summarizing the key findings, highlighting the advantages of Windows OS and the importance of switches and routers in network design. Finally, the report references relevant books, journals, and online resources for further study. The report covers network design and its simulation in order to establish a powerful network.

INTRODUCTION
Before designing a network, it is important that requirements are identified. This is
because the network is entirely based on the components and their features. Each component has
its own features that can be installed in network according to its range and capacity.
PART 1
In order identify the requirements of network information needs to be collected. This is
because it helps in determining the needs and requirements (Din, Hassan and Habbal, 2015). In a
business the information is collected from users, management, etc.
A questionnaire is developed in order to collect information about requirements of
network. These are then distributed to management of sports complex so that applications and
devices can be determined. The questionnaire is as follows :-
Questionnaire
Q-1 What type of server or operating system should be installed in network?
 Microsoft windows
 Linux
Q-2 What type of desktop operating system is required?
 DOS
 Windows
 Macintosh
Q-3 Do we need 1 or more than 1 hub or router in network?
 Yes
 No
Q-4 How many users will have access to key application system?
 1-2
 2-3
 More than 3
Q-5 What will be more useful for the network?
1

 Router
 Switch
Q-6 Do you need a VPN in order to access the third party network?
 Yes
 No
Q-1 After gathering the information from the above first question we found that Microsoft is
much more user friendly operating system then Linux (Eftekhari, Ghahfarokh and Moghim,
2015). Microsoft office provides those features which are easily understandable and
approachable so most of the people prefer to install this kind of OS. This software is also easy to
install and provides variety of software programs.
Q-2 After an abstracted survey from various types of users we have concluded that people like to
run multiple tasks simultaneously. So for this purpose will go for the concept of single user
multiple tasking operating system. Windows OS facilitates users to run different types of
applications together.
Q-3 It is an obvious thing that networking is surrounded with wide range of user requests aimed
at gathering data and information. To avoid unwanted traffic from server more than one hub and
routers to direct the request towards server. So in this situation when we approached bulk of
masses to get this answer, we found that users requests for multiple queries at the same time. So
if they got quick respond from a particular site then they will be highly satisfied and rejects other
responding sites in order to get quick answer. In this case they need more than one router and
hub to get faster and effective response of request.
Q-4 It was found that users are nowadays taking interests in the technological advancement. So
to develop applications and tools for the betterment of society they need accessing power to
approach key application system. But it is not necessary that all the users can be allowed to get
access so considering this thing in mind developers have provided various interfaces to users to
operate applications and software. It is enough to have access of key application among two or
three users.
Q-5 After gathering a vast knowledge related to the networking and its benefits it is obtained that
switches are used to take information of user requests in small packets and then delivers the data
with a comprehensive collection of all the packets through different routers. Switches are
2

important to take the information and data in small parts and these packets will find a shortest
distance to reach destination so both of these networking devices are important.
Q-6 Use of virtual private network is used to develop a secure connection over the internet. So
yes it is required that this network need to be accessed by third party to establish a effective
network.
Demonstration of network design using simulator and also application sets to achieve application
performance factor
Networking is considered as well defined structure of devices which are connected
together in order to share information (Mastorakis and et al., 2015). Some networking tools or
simulations are used to get the effective system of networking. Networking consists of multiple
simulations such as Network simulator 2 (Ns2), Ns3, OPNET, OMNeT++, Netsim, REAL,
Qualnet, J-Sim etc (Advances in Network Simulatio, 2018).
From the list of these tools REAL is considered as the most popular technique in which
flow of data is controlled. This simulator is useful in managing packet switch and data networks.
It is generally programmed in C language (Zhao and et.al., 2016). It is used for understanding
dynamic behavior of data flow and congestion control of networking.

The above diagram shows that network developed follows from top to bottom down
approach. In this there are various applications and devices installed.
Plan to verify the gathered requirements from different stack holders
Networking is itself a huge bundle of knowledge which is changing day by day. So
management has to plan the requirements. Questionnaire is able to sufficiently and effectively
throw questions in order to collect some information regarding the networking and its
functioning (Zhao and et.al., 2016). After a powerful survey questionnaire is able to get all the
information about the use of operating system and switching and their packets (Network simulatio,
2018).

A wireless computer network can also be considered as basic service set because it is
used to link two or more devices together. Basically it is considered as a set of all stations which
ensures the communication of each workstation with each other. For example Basic service Set
(BSS) is used to provide services to the different networks(Eftekhari, Ghahfarokh and Moghim,
2015). These applications set help us to transfer data from one point of network to another
destination.
CONCLUSION
It is concluded that windows operating system was considered as best option for users as
it provides user friendly features to the user. It was also found that switch and routers are the two
5

most popular requirements of networking. This report was able to identify requirements and tools
of networking. The study had covered networking design and its simulation in order to establish
a powerful network. It had also provided a tabular description about application sets and its
various systems.
