What is VPN?

VPN (Virtual Private Network) uses public network such as internet to provide the remote offices the secure access to their organizationâ s network. VPN is an alternative to the expensive system of the leased lines that are owned and used by an organization. VPN maintains the privacy and security by the security procedures and tunneling protocols such as PPTP (Point to point tunneling protocol), IPSec, L2TP, L2TPv3, L2F and MPLS (Multi Protocol Label Switching).
A VPN network can send voice, data, and video over secure and encrypted private channels in the public network. There are many VPN client programs that are configure in such a way that all the IP traffic must pass the VPN tunnels before reaching the destination
