Virtual Private Network
A discussion on the V.P.N and its advantages.
This paper discusses the advantages of setting up a Virtual Private Network (VPN). The author introduces the definition of VPN, lists the types of existing VPN systems, and examines relevant security and encryption issues.
“There are many reasons for setting up a Virtual Private Network, but the most important one is the potential cost saving. When the Internet is used to distribute network services over long distances, companies no longer have to purchase expensive private leased lines to link various offices. A VPN needs only a short dedicated connection. A local broadband connection or a leased line would do. This point is most important in a rapidly expanding organization. If normal point to point leased lines are used, the costs of the lines increases exponentially with the growth, and at a time, it will become the limiting factor in the organizations growth. VPNs do not have this problem, as whenever a new location is opened, they just have to tap into the universally available network. Another way that the VPNs reduce communication costs is on a recurring basis. This is the monthly phone bills that are saved. This is especially noticed if the company has international sites, as savings here can run into the thousands. All the users have to do now is to dial a local, or an 800 number, and logon to their network. Another major way that VPNs reduce cost is by reducing the maintenance and network support burden. The service provider must now support the dial up access, and the user no longer has to pay for the pools of modems, and other components of the network such as the remote access servers and other WAN equipment. The user can now get away with his normal Internet setup.”
