Increase WAN Network Reliability

Just as RAID added significantly to the reliability of storage systems while using inexpensive, "lower quality" hard disks than prior storage systems, an Adaptive Private Networking (APN) solution similarly delivers increased network reliability and application predictability over single-provider WANs, even as it lowers monthly WAN costs and provides greater bandwidth.

Most obviously, rather than depending on an SLA from a service provider – where, after all, if the SP is in non-compliance, you simply get a 10% credit on the monthly bill (not what you actually care about in such a situation!) – APN’s ability to use multiple active, load-sharing connections between locations provides uptime and predictable performance. With sub-second response to failure, packet loss or other congestion events, no single WAN link failure, nor any other single problem in the network, can cause a loss of connectivity.

Even for those willing to “pay through the nose” for dual MPLS networks from different providers, Adaptive Private Networking provides a level of network reliability and application predictability unavailable using standard routed networks and routing protocols. With APN’s Multipath Network Spectrometry continuously measuring the state of all network paths, you avoid the possibility that your backup connection – probably rarely used – itself has a problem, or is misconfigured, just when you need it most: when trouble does occur on your primary network.

With APN, you can eliminate an expensive redundant MPLS network – substituting inexpensive Internet connections and APN’s Resilient Multipath Connectivity for that second MPLS network – and have more reliability and application predictability, more usable bandwidth, and a lower monthly WAN bill at the same time.

In addition to reacting more quickly (sub-second) to hard network or device failures, where routing protocols can sometimes require up to 30 seconds to react, Adaptive Private Networking also protects you from the performance problems that can occur dues to loss or congestion on the WAN. And while it is true that these “network brownouts” rarely occur on over-engineered North American MPLS networks, they do occur with at least some frequency in international MPLS networks, especially in the Asia-Pacific region.

In fact, given that APN's inherent nature is to adapt in the face of WAN connectivity problems, an Adaptive Private Networking solution from Talari Networks actually makes your WAN incredibly fault-tolerant, even to problems caused by a faulty software upgrade or misconfigured router on your own network.
