VPN Services

Virtual private networks (VPNs) are logically partitioned, private networks constructed over a shared or public infrastructure that utilizes a range of technologies to ensure traffic separation and privacy of data, either self-implemented or provided by a service provider. A VPN can be built on the Internet or on a service provider's IP, Frame Relay, or ATM infrastructure.

Businesses that run their VPNs over a shared or public infrastructure enjoy the same security, quality of service (QoS), reliability, and manageability as they do in their own private networks. VPNs allow the end customer to realize the cost advantages of shared network.

The two basic types of VPN services are Access VPNs and Site-to-Site VPNs. The three main applications are for remote access, intranet and extranet connectivity.
