NEW TRENDS IN NETWORKING

ABSTRACT:

In today’s New Economy, small businesses that might have dealt with just local or regional concerns now have to consider global markets and logistics. At the same time security concerns of their network from hackers, Denial-of-Service (DoS) attacks and sending data over the Internet have become more widespread.

Until recently,communications were only available by using leased telephone lines to maintain a Wide Area Network (WAN). Leased lines enabled companies to expand their private network beyond their immediate geographic area. Moreover, WAN provided advantages over a public network like the Internet when it came to reliability, performance, and security.

The continuing popularity with the Internet has led to the evolution of Virtual Private Networks (VPNs). A VPN is a connection that allows private data to be sent securely over a shared or public network, such as the Internet. In fact, one of the driving forces behind VPNs is the Internet and its global presence.

With VPNs, communication links between users and sites can be achieved quickly, inexpensively, and safely across the world. In this way, VPNs empower organizations to extend their network service to branch offices and remote users -such as traveling employees, telecommuters, and strategic partners -by creating a private WAN via the Internet. With all these benefits, small businesses are also eager to reap the advantages afforded by VPNs. This paper explains what a VPN is and how VPNs provide secure, private connections to network applications.

By reading this paper, you will gain a fundamental understanding of VPNs, including their security mechanisms, benefits, and cost-saving advantages.
