Virtual Private Networks (VPNs) extend the corporate network out to distant offices, home workers, sales people, and business partners. But, rather than using expensive dedicated leased lines, VPNs use world wide IP network services, including the internet "cloud" and service providers' IP backbones.
VPNs are extensively used by organizations worldwide, to run their business critical applications like Intranets, Extranets, and ERP applications.
Virtual Private Networks deliver enterprise-scale connectivity deployed on a shared infrastructure with the same policies that are enjoyed in a private network. Businesses that run their applications over a VPN enjoy security, prioritization, manageability, and reliability to levels similar to those in private networks.
VPNs allow:
-- Network managers to cost-efficiently increase the span of the corporate network.
-- Remote network users to securely and easily access their corporate enterprise without resorting to expensive leased line connections and remote access equipment.
-- Corporations to securely communicate with business partners.
-- Service providers to expand their businesses by providing substantial incremental bandwidth and value added services.
