Talari Networks delivers better WAN performance than what an enterprise can achieve with a single-vendor MPLS WAN by aggregating multiple WAN or broadband links. Through its Adaptive Private Network (APN) technology, Talari Mercury appliances provide multiple advanced features including:
Per-packet Path Selection for Application Continuity
With Talari, path selection is performed for every single data packet. Per-packet path selection allows sub-second switchover to a better path in the middle of an application session if the current path becomes unavailable or its performance degrades. As a result, the application session will not be interrupted and the switchover is totally seamless, even for real-time applications such as VoIP.
Accurate and Continuous WAN Health Monitoring for Better User Experience
Talari's forwarding decisions are based on the appliances' automated collection of rich real-time information. Mercury devices continuously monitor the health of each network path and measure performance metrics relevant to IP networks such as one-way packet delay, jitter, and packet loss. Metrics are measured for every packet and measurement results are used to define path status and reported to the management application.
Resiliency at Low Price
At its core, Talari enables network managers to use multiple WAN connections—existing private WANs such as MPLS, as well as any kind of Internet WAN links, such as DSL, cable, fiber, Metro Ethernet, etc.—to augment or replace individual private WAN connections. Talari appliances use end-to-end algorithms to react in sub-second to not just link failures but also congestion-related network problems, enabling businesses to build a WAN that is more resilient, less expensive, and with lower ongoing operational costs than today's proprietary, single vendor WANs.
Dynamic Bandwidth Management and Aggregation
With its patented APN technology, Talari can increase bandwidth by leveraging Internet links that are today only used as VPN backup connections and/or for local Internet access. Bandwidth management algorithm is dynamic and takes into account instantaneous use of bandwidth by local and remote sites. Additionally, per-packet path selection allows each application session to use all available WAN links, resulting in better application performance and more satisfied users. Policies can be established for up to 16 classes of application traffic, ensuring that in cases of poor quality lines or restricted bandwidth higher priority real-time applications can take precedence over lower priority processes such as file backup.
For enterprises looking to centralize more services at their data centers, predictable application performance over a cost effective WAN infrastructure and high reliability are key requirements. The APN High-Availability functionality eliminates the APN appliance as a single point of failure in the network by providing complete redundancy between two Talari appliances. The pre-designated "standby" appliance monitors the state of the "active" appliance and, in the event of a failure, takes over all APN services. Using a Redundant APN Control Protocol (RACP), the Talari High Availability system can detect a failure in the active appliance and switch over all functions to the standby appliance in a fraction of a second, in a way that is transparent to most active applications.
Note: This feature is supported on Mercury T730 appliance and above.
With the Geographic Redundancy feature, an APN client node can also function as a secondary APN control node (NCN). In the event of a primary data center failure, the backup data center will become operational and the secondary Talari appliance will act as the NCN for the APN. This provides protection against a catastrophic failure in the primary location.
Note: This feature is supported on Mercury T750 appliance and above.
Talari Networks' family of Mercury appliances scales easily to fit the needs of every location in your business. For large central sites such as call centers and data centers, the Mercury family offers the T5000, which supports aggregated WAN bandwidth of 3Gbps full-duplex and is optimized for very large number of small packets, typical of applications such as VoIP. The 3000H and T3000L are ideal for data centers and headquarters. The T750 supports smaller data centers and larger branch offices while the T730 is ideal for medium sized remote offices. And to bring reliability and increased bandwidth to locations typically served by IPsec VPNs, Talari offers the small office/home office T510 model.
"When latency begins to build up, the secondary links become more attractive and Talari starts pushing more traffic onto the DSL Links to balance our traffic levels."

"Solving the reliability issues around public Internet connections means that Internet ubiquity and low cost can finally be of benefit for Enterprise networking folks to provide better and more predictable application performance to their end users."
John Bartlet, Vice President
"Finally someone gets it. Talari's technology allows us to route each packet over the best, most reliable route, over multiple paths, regardless of whether those are private line, MPLS, DSL, cable modem, or whatever. It aggregates different types of connectivity transparently to create our own big, private tunnel across the Internet."
