Talari Networks Adaptive Private Networking Technology
Adaptive Private Networking (APN) from Talari Networks delivers more bandwidth, lower monthly WAN costs and greater network reliability than the best single Frame Relay or MPLS network can provide.
For real-time applications like VoIP and videoconferencing, APN uniquely delivers ultra-reliable, cost-effective support. It routinely chooses network paths with the least packet loss and lowest jitter for such high-priority real-time traffic, and switches with sub-second response to a better path in the face of high loss or jitter. Where bandwidth availability allows, APN provides still further protection by replicating real-time traffic flows along a second path, suppressing duplicates at the receiving end, delivering "platinum quality" connectivity.
APN's sophisticated decision making is powered by two key component technologies. Talari's Multipath Network Spectrometry is the key enabling technology providing the rich real-time information that lets APN work its magic. Resilient Multipath Connectivity technology in turn delivers end-to-end reliability and protected application performance, for both TCP-based apps and real-time applications like VoIP and videoconferencing.

APN provides multi-path multiplexing for both aggregating bandwidth and delivering end-to-end reliability, dynamically engineering around network trouble - not just outright link failure, but high packet loss or excess latency - as it occurs. It adapts to such "network events" within ~250 milliseconds for domestic connections, or ~500-600 milliseconds even for longer-distance international connections. This sub-second response is more than fast enough to handle any IP application that can run on an IP WAN.
The intelligent actions and sub-second reaction in the face of packet loss provide predictable, protected application performance for any TCP-based application. APN makes the WAN look to each TCP application as if it were a zero-packet-loss WAN with the occasional bout of jitter-something TCP and TCP-based applications are designed to expect and accommodate without incident.
Talari Multipath Bandwidth Spectrometry
APN’s forwarding decisions are based on the Talari devices’ automated collection of rich real-time information. Multipath Bandwidth Spectrometry is the key technology that lets Talari work its magic. Classically, spectrometry is a highly precise view of an object’s detailed characteristics, possible with the tiniest of samples.

By analogy, Bandwidth Spectrometry is a highly precise view of each network path’s detailed characteristics, including loss, latency and jitter. It is measured continuously on an individual packet-by-packet basis. When (and only when) no traffic is using the path, heartbeat packets provide the means to have these measurements continuously available.
Multipath Bandwidth Spectrometry performs continuous, advanced, multipath, intelligent WAN monitoring at the packet, link, and network-path level. It uses dynamic, end-to-end algorithms to track loss, latency, and jitter per network connection, not just for a local link. It uses per-packet encapsulation, timestamping and sequencing to help achieve this.
