Virtual Private Networks: Solutions for Cost-Effective, High-Speed Corporate Extranets and Wide-Area Networks.

Tags: vpn, wan, remote access, computing, data

Overview Virtual Private Networks (VPNs) have been used increasingly since 1997 to allow businesses to link separate Local Area Networks (LANs), build Wide Area Networks (WANs), create extranets with suppliers, or provide secure remote access. Because a VPN does not require dedicated E1 or DDN lines, this technology is a particularly attractive option to Small and Medium Enterprises (SMEs) which need to link their computing resources. However, there are many pitfalls to be negotiated in setting up a VPN, ranging from conflicts between security protocols and firewalls, to slow data transfer due to choice of access methods. This paper covers the basics of VPNs. Its main focus is to examine the various options for creating a VPN to suit the business and data needs.
