Traditional Virtual Private Networks Don't Deliver for Business

Claranet’s Group Product Manager, Martin Saunders will tell delegates at IP ’06 that most virtual private networks are inadequate for contemporary business practice. He will demonstrate how the virtual private network (VPN) services most commonly offered by ISPs fail businesses.

This is due to a combination of three main issues. These are:

1) The limitations of service providers’ network footprints

2) Problems attaining quality of service from applications over VPNs

3) Restrictions on types of Internet connection that enable access to the VPN

“Businesses are generally offered a one size fits all solution to their request for a virtual private network solution. The VPNs take the form of either the overlay or the network model,��? says Mr Saunders.

Any advantages of network VPNs are limited by the reach of the service providers’ network. Although the overlay model offers solutions to the problems of the network model, overlay VPNs are notoriously expensive and inefficient to scale, and application quality of service is almost impossible to implement.

In response to customer feedback and in line with Claranet’s commitment to provide flexible Internet infrastructure that performs to customers’ requirements, the company’s technicians have developed a hybrid, next generation VPN model - VPN:NG.

Mr Saunders says, “VPN:NG mixes the benefits of the network model with those of the overlay VPN. It’s carrier neutral and as a hybrid, it offers a multitude of access options, including DSL, leased lines and Wifi.

It also enables a variety of applications to run over the VPN at the same time including voice, electronic point of sale, peer-to-peer and Citrix or a terminal server type application.

VPN:NG is available across Claranet’s wide and unified network operating in six European countries and the US, and is backed up by an industry leading service level agreement.��?
