Abstract:
Adaptive Private Networking (APN) is an emerging way to create virtual WANs. When compared to traditional WAN services such as Frame Relay and MPLS, APNs provide both higher levels of reliability , dramatic cost savings, and significantly more bandwidth. An APN is based on packet-by-packet, real-time traffic engineering that leverages the reliability and bandwidth of multiple active paths through the Internet. The reliability improvement that APN delivers by leveraging multiple active paths allows an APN to exploit the superior price/performance of consumer-oriented ISP services.
APNs offer the following benefits:
 |
30 - 100 times more bandwidth per dollar than Frame Relay or MPLS services |
|
|
40% - 90% monthly WAN expense reduction |
|
|
Payback in 4 - 9 months when migrating completely from Frame Relay or MPLS services |
|
|
Payback in 8 - 12 months for partial migrations |
|
|
End-to-End QoS functionality |
|
|
Greater availability and reliability than typical Frame Relay or MPLS services |
To demonstrate the benefits that APN offers, this white paper analyzes how medium to large-sized companies can save in excess of three million dollars in WAN costs over a three-year period while increasing available bandwidth to its branch offices by up to an order of magnitude.
