Abstract
The sole purpose to study Enterprise Network is to create business simplicity across
worldwide. The side arms of successful networking are scalability, robustness, fault
identification, communication, modularity, security and maintaining privacy. The key
for making a network is to provide the essential tools and techniques that will offer
the quality of a private/public network.
As I discussed earlier the key purpose is to create business simplicity that means
creating IT/Infrastructure simplicity across the cities where an Enterprise Network is
connected. Obtaining success in failure/break-down conditions is the main purpose of
a network. So to achieve that requirement network designing involves certain
topologies, protocols, bandwidth allocation. Topology requirement can be described
as maintaining two adjacent networks against any failure in a single link or node.
Protocol requirement can be described as using dynamic/static routing protocol to
provide routes must be congestion free in a network. Bandwidth allocation is needed
to actively allocate extra bandwidth just to maintain the working condition in a
network. Design and Modification criteria is all over handed to a person called
Network Administrator, who maintains and solely responsible for anything(wanted or
unwanted) happens in a network.

CHAPTER 1______________________________
Introduction
1.1 What is Enterprise Network?
An enterprise network is a communication backbone that helps connect computers
and related devices (smartphones) across various departments in an organization. An
enterprise network helps to minimize the complexity through simplification of various
communication protocols, improving system as well as internal and external
enterprise data management.
Enterprise Networks simplifies IT operations and creates new possible business
opportunities with a flexible end and programmable purpose to networking.
1.2 Overview
1. Networking and Applications
2. Connectivity and Services
3. Maintenance
4. Fault tolerance
5. Load balancing
6. Integration across systems
7. Security
(1)

1.3 What is End to End solution?
At first we have to know what is the basic need for end to end solution in case of an
Enterprise network? So from a basic human common sense we can think what is the
reason for simplifying?
The answer comes to our mind which is
1. Simplifying (through modification) networking operations done in a private or
public network.
2. Increase in financial output of a government or private organization.
Rapid increase in smartphone user computer devices and has created huge traffic
congestion in network and complexity. Useful applications are experiencing an 80
percent increase rate in usage. Networks are failing to keep compatibility with rapid
changes in compute operations, which often produce problem in end-to-end delivery.
From the figure 1 we can see that an enterprise network is created amongst different
locations where the routers are connected through different vast locations like
Punjab, Haryana, Noida, Canada, USA, Dehradun, Greater Noida, Gurgaon, Delhi
and 24 port 3560 multilayer switches are connected with the routers and the servers
are used for creating server pools across the network. I used switches for creating
connectivity through router from private pcs.so if the user from USA wants to connect
with the user of Noida, traffic congestion arises ass it covers a vast distance along
with network congestion. So here to simplify the networking path, End to End
Enterprise Network Solution is needed.

1.4 Architecture
1. Nano level architecture (A Single PC in an Organization)
(Issue- Application related) (EX- A student in AMITY)(A single machine and a
router)
2. Micro level architecture (A Single Subnet in an Organization)
(Issue-Resource sharing)(Ex-A lab in AMITY)(Approximately 10’s of machines, 1-2
switches, 1000m cabling)
3. Mili level architecture (A Single Entity in large Office)
(Issue-Management and deployment)(Ex-AITEM in AMITY)(Approximately 100’s
of machines, 10-20’s switches, 3-5 Routers, 5 servers)
4. Typical level architecture (A Single Organization)
(Issues- Different resource monitoring)(Ex-AMITY)(Approximately 10’s locations,
1000’s of machines, 100’s of switches, 10’s of routers)
5. Kilo level architecture (National Network)
(Issue- Scalability) (Ex-LIC)(Approximately 100’s of locations, 10000’s of machines,
1000’s of switches, 100’s of routers)
6. Mega level architecture (Wide Network for a single organization)
(Issue-Robustness)(Ex-INTEL)(Approximately 10’s of countries, 1000s of locations)
7. Giga level architecture (Wireless Access)
(Issue-Control operations)(100’s of organizations, 100’s of countries, billions of
devices)
(3)

FIG 1 Enterprise Network (Structure)
So as we can say in the image that an ENTERPRISE NETWORK supports thousands
of users across the wide geographical range of a company including thousands of
servers in each of the cities, each system is linked with each other in the network so
here complexity arises.
1. It is large as it can include 100000’s edge devices and 10000’s network devices.
2. It is Geographically Distributed amongst multiple countries.
3. The Network Administrator has the supreme priority over the entire network.
(4)

1.5 Why we should study Enterprise Network?
1.5.1 Money/Fund
Enterprise IT industries are spending lots of funds to improve, which is expected to
increase steadily. In India rapid growth of IT Services as well as IT related business
complexity is the main sole reason for investing in Enterprise IT applications and its
infrastructure to minimize the level of complexity. Right now it’s about 200 million
dollar spent.
1.5.2 Challenging Problems
1. Resource Management.
2. Network security and privacy management.
3. Capacity of a private or public network.
1.5.3 Others
1. Increasing gadgets (smartphones, tablets and laptops) and broadband access-
technologies demand for new services and applications worldwide.
(5)

1.6 Where the money is being spent??
1. Increasing connectivity requirements including VPN solutions.
2. Maintaining corporate information and resources.
3. Wide range of services including mobile devices.
4. IT applications for health purpose, financial purposes.
5. Security solutions for multinational corporate offices.
FIG 2 Enterprise IT Spending (2013 Budget)
(6)

1.7 Theme
Enterprise Network is the basic solution with respect to business and financial view of
an organization. It simply offers great value by creating End to End solution and as
the whole control of this network can be handled over the priority of a Network
Administrator so it can be integrated and improved in future if we need it.
1.8 Organization
Hewlett-Packard Company or HP is an American multinational information
technology corporation headquartered in Palo Alto, California, United States. It
provides hardware, software and services to consumers, small and medium-sized

CHAPTER 4_____________________________
Conclusion
To conclude I would like to say that I have successfully completed the basic and soul
purpose of my project which is to create an Enterprise Network which offers End to
End Solution across multiple cities, Countries through which it is connected.
The Basic Fundamentals and aims I think I have successfully achieved and
implemented but as nothing can be perfect so as my project, it needs better
implications in future.
According to me I have completed my project still I am left with lots of improvements
and enhancements of this projected structure. I will try my level best to complete it in
my near future.
(28)

Recommendations
Although I have completed my project successfully but there can be made few
extensions
1. CISCO PACKET TRACER should be updated to next version, as it lags
sometimes.
2. Using different colors in the software makes it easy to understand the difficult
network architecture.
3. Try to make a network which is broader to understand, means there should be
sufficient gap between router switch and multilayer switches of different cities
(29)

CHAPTER 5_____________________________
Implications for Future Research
The Enterprise of the Future will need to be hungry for change and disruptive by
nature, innovative beyond customer imagination, global integrated, and genuine, not
simply generous in their corporate social responsibility efforts. Each of these issues
has clear implications for the workforce, and for the leaders of the Human Resources
function who are working to enhance organizational effectiveness.
Building the Enterprise of the Future: The
Workforce
Dimension
The Enterprise Network of the Future is globally integrated and designed – leveraging
the most appropriate talent and expertise regardless of its geographic location. To
make the most of a global workforce organizations need to develop an HR capability
that can deliver cost-effective services to a global population, provide an
infrastructure that enables individuals to work together regardless of their locations,
and develop leadership competencies that can deliver results and provide guidance to
a myriad of stakeholders. Lastly, corporate social responsibility is playing a larger
role in today’s enterprises. Engaging the workforce in these efforts can have a positive
impact on both employee attraction and retention, yet many companies have not
engaged the workforce around this topic.

CHAPTER 6 ___________________________
Appendix
Working in CISCO Packet Tracer Software is very interesting according to me. We
know our generation is fond of mobiles and their configuration (Android, IOS,
Symbian) Going through the CISCO Packet Tracer software I understood that it is
very similar because everything you are configuring is clearly visible as there is not
any virtual level, you can test your correctness of configuration while you are writing
the program, may be in routers, in switches or in servers(Command Line Interface or
in Global Configuration Mode).It was a nice experience of 6 weeks working in this
highly customizable Network Simulation Software.
