Virtual Private Networks
For customers who want to realize the cost benefits of a shared network but do not require the level of performance and security of our managed data networking services, we offer our
Internet-based virtual private network services.
Virtual private networks utilize the near-ubiquity of the Internet to provide cost effective connectivity for businesses with large numbers of sites, sites that do not have high bandwidth requirements, sites that are in remote locations or mobile workers.
A typical Internet-based virtual private network supports dial-up access, resulting in extensive geographic coverage and, together with the implementation of tunneling, encryption, authentication and access control technologies, can establish a secure link between the mobile worker and the corporate network environment.
One of our-primary competitive advantages is that our, virtual private network customers are served by our high performance network.
What are the advantages of an IP VPN?
Privacy: Advances in Internet technology now make it possible to access a low cost global network without compromising your privacy. Enhanced Internet security is achieved by using either application-level encryption or network layer encryption gateways and routers, with a firewall for additional security.
Cost: An Internet-based connection offers a cost saving over a dedicated, leased-line WAN for several reasons including:
- Conventional private network line costs are based on a fixed fee for connectivity plus a per-mile distance charge so, as the network's reach grows - so do the costs. By contrast, Internet based connections, are largely distance-insensitive.
- Internet infrastructure is 'already installed' throughout the world so when you set up your private network there are significantly fewer costs incurred in installing new lines etc.
- If you choose a fully managed service, your operational costs per VPN site are significantly reduced.
Flexibility: An Internet Protocol-based network offers a greater variety of access methods than a private traditional WAN. Businesses can choose from a variety of bandwidth capacity ranges and billing models. And even systems that do not completely comply with Internet standards can take advantage of the Internet through protocol tunneling and application proxying.
Coverage: Internet networks already cover the majority of business centers around the world. And coverage is probably the single biggest advantage of moving your VPN onto an IP-based infrastructure. Unlike dedicated telco lines having a point-to-point connection, the Internet network resembles a tightly-woven mesh of a multitude of networks, all being connected to each other, reaching most corners of the planet.
Scalability: Because Internet infrastructure is already in place throughout many areas of the world, and because systems such as the Xedia QVPN builder can automate the process of configuring the VPN, Internet VPNs can be very scalable compared to conventional WANs. This can make it much simpler, faster and cheaper to add new sites to your network. |
