An enterprise private network is a computer network controlled by a single organization that connects multiple offices and locations. It allows resources like student information, teacher information, and finance systems to be securely shared across locations. Enterprise private networks first emerged in the 1970s and were built over telecom networks, but now often use virtual private network technology and encryption over public internet infrastructure. For example, one organization describes its use of a Layer 2 MPLS network with hub and spoke topology to connect various campuses and departments.

3. TELECOMMUNICATION NETWORK
• A telecommunication
network is a collection of
terminal nodes, links which
are connected so as to enable
telecommunication between
the terminals. The
transmission links connect
the nodes together. ...
computer networks. the
Internet. the telephone
network.

4. TYPES OF TELECOMMUNICATION NETWORKS
There are many different network structures to
efficiently route messages, for example:
• Wide area networks (WAN)
• Metropolitan area networks (MAN)
• Local area networks (LAN)
• Internet area networks (IAN)
• Campus area networks (CAN)
• Virtual private networks (VPN)
• Enterprise private networks (EPN)

5. ENTERPRISE PRIVATE NETWORK (EPN)
• An enterprise private network is a computer
network that helps enterprise companies with a
number of disparate offices connect those offices
to each in a secure way over a network. An
enterprise private network is mainly set up to
share computer resources.
• It is a computer network that is entirely
controlled by one organisation and it is used to
connect multiple locations.

7. HISTORY
• In the U.S., private networks were started in the early 1970s by
AT&T. The networks were mainly operated over
telecommunications networks. During 1990s as Internet
technology evolved, a new type of network called virtual private
networks originated. This type of network was built over public
infrastructure, and the data was encrypted to protect it from
eavesdroppers.
• Nowadays, networks built by companies are still called enterprise
private networks when privacy is maintained through security
procedures and tunneling protocols like Layer 2 Tunneling
Protocol.

• Security
• Sharing
• Centralize (communication)
• It help in business continuity and development.

10. USEFUL INFORMATION
Many business applications of telecommunication involve the use of the internet,
extranet, and other networks to form interenterprise networks.
Such networks link a company’s headquarters and other location to the networks of
its customer, suppliers and other organization.
For example:
You think of a customer account inquiry system that provides intranet access by
employees and extranet access by customer.so it is an other example of
interenterprise network.
So is the use of Electronic data interchange.(EDI) systems that link the
computers of a company with those of its suppliers and customers for the electronic
exchange of business documents.

12. INTRANET
EXTRANET
It is a computer network system in which a specific organisation system
information computing services and operational system with each othe
the use of internet (IP) technology.
It is a type of computer network that allows the
outside users to access the intranet of organisation.

13. INTERNET
• The Internet is the global system of
interconnected computer networks that
use the Internet protocol suite (TCP) to
link devices worldwide.
• The World Wide Web is one of its biggest
services.

14. ELECTRONIC DATA INTERCHANGE
• Electronic Data Interchange (EDI) is the computer-to-
computer exchange of business documents in a standard
electronic format between business partners.
BENIFITS
Businesses enjoy major benefits such as
• Reduced cost.
• Increased processing speed.
• Reduced errors and improved relationships with business
partners.

15. BUSINESS DOCUMENTS
These are any of the documents that are typically exchanged
between businesses. The most common documents exchanged
via EDI are
• purchase orders
• invoices
• advance ship notices.
• But there are many, many others such as bill of lading, customs
documents, inventory documents, shipping status documents
and payment documents.
• A standard format must be used so that the computer will be
able to read and understand the documents.

16. BELOW IS AN OUTLINE OF THE DIFFERENT
METHODS AVAILABLE
• Direct EDI/Point-to-Point
• EDI via VAN
• EDI Network Services Provider
• EDI via AS2
• EDI via FTP/VPN, SFTP, FTPS Web
• EDI Mobile EDI
• EDI Outsourcing
• EDI Software

17. WORLD WIDE WEB
• It is a standard to communicate on web and
publication information.
• It provide base to different software's and for
different languages
