Next-Generation WANs Without Compromise

Talari Networks™ Adaptive Private Networking (APN) technology for WAN Virtualization combines diverse, abundant, affordable IP bandwidth sources, applying a RAID-like approach to WAN connections to solve the reliability and predictability issues associated with shared-IP networks. The result? Next-generation Enterprise WANs without compromise:

• Significantly higher bandwidth
• Business quality, self healing
• Radically lower cost

The WAN Service Price-Quality Disconnect

The Enterprise WAN service market has been static for years. The introduction of Frame Relay in the early 1990s brought lower cost, higher bandwidth, solid reliability and easier manageability to building Enterprise WANs over the then-prevalent X.25 and point-to-point leased-line alternatives. Frame Relay, together with similarly priced, single-source ATM and MPLS services, still dominates the Enterprise WAN market for corporate Intranet traffic. What these services all have in common is that a customer buys reliable (“3½ nines”, i.e., 99.95%, or better) service and bandwidth end-to-end from a single carrier, at a price (on a cost-per-Mbps basis) almost as high as what they paid back in 1998!

The cost of operating carrier networks, however, has fallen along with Moore’s Law, as have the prices of alternate-Internet and broadband-based WAN solutions. Where Frame Relay, ATM or MPLS bandwidth for branch connectivity costs anywhere from $375 to $2500 per Mbps per month, broadband connectivity is widely available at a monthly cost of only $4 to $15 per Mbps. At the same time, the bandwidth of these broadband and Internet networks has improved, as has their reliability, even if they are not yet “business quality."

The Talari Networks Solution

That’s where WAN Virtualization and Talari Networks comes in. By solving the reliability and predictability issues associated with shared-IP networks, in general, and the public Internet in particular, our WAN Virtualization solution enables Enterprises to gain a step-function improvement in their WAN operations.

In the same way that RAID (Redundant Array of Inexpensive Disks) revolutionized high-end data storage, WAN Virtualization is revolutionizing corporate WANs. WAN Virtualization applies to WAN data connections a unique combination of RAID-like methods and overlay networking techniques, like those used by services such as Skype or Vonage in delivering voice over the public Internet. By leveraging network bandwidth from multiple sources – including both high-speed Internet connections at central locations and broadband connections (DSL, cable where available) at branch locations – WAN Virtualization allows businesses for the first time to take advantage of the economics of broadband and the public Internet without sacrificing business-quality reliability and availability.

No one today builds monolithic, proprietary, single-disk storage solutions; they use RAID technology to get greater capacity and performance, lower cost, and higher reliability. With Talari Networks’ Adaptive Private Networking, Enterprise managers can take the same approach to building corporate WANs. No longer must businesses purchase overpriced, “over-engineered” network services from a single telecom provider. APN delivers more bandwidth, lower monthly WAN costs and greater network reliability than the best single Frame Relay or MPLS network can provide.
