what is virtual private network

May 21, 2010 at 2:40 am | blog | No comment

MultiService Virtual Private Network Service (MultiService VPN) service is one package of data communications solutions that provide services to end users using the IP-based MPLS (Multi Protocol Label Switch) that is safe for relationship Wide Area Network (WAN). Sharing network of MPLS label swapping capability combined with network layer routing to form a private network that is safe and fast delivery of information packets. With the network architecture network costs more competitive.

he VPN can be found in workplaces and homes, where they allow employees to safely log into company networks. Telecommuters and those who travel often find a VPN a more convenient way to stay connected to the corporate intranet. No matter your current involvement with VPNs, this is a good technology to know something about. This VPN tutorial involves many interesting aspects of network protocol design, Internet security, network service outsourcing, and technology standards.

VPN supports two types of tunneling – voluntary and compulsory. Both types of tunneling are commonly used.

In voluntary tunneling, the VPN client manages connection setup. The client first makes a connection to the carrier network provider (an ISP in the case of Internet VPNs). Then, the VPN client application creates the tunnel to a VPN server over this live connection.

In compulsory tunneling, the carrier network provider manages VPN connection setup. When the client first makes an ordinary connection to the carrier, the carrier in turn immediately brokers a VPN connection between that client and a VPN server. From the client point of view, VPN connections are set up in just one step compared to the two-step procedure required for voluntary tunnels.

Compulsory VPN tunneling authenticates clients and associates them with specific VPN servers using logic built into the broker device. This network device is sometimes called the VPN Front End Processor (FEP), Network Access Server (NAS) or Point of Presence Server (POS). Compulsory tunneling hides the details of VPN server connectivity from the VPN clients and effectively transfers management control over the tunnels from clients to the ISP. In return, service providers must take on the additional burden of installing and maintaining FEP devices.
