Next-Generation Enterprise WANs Without Compromise

Talari's Mercury Appliances combine diverse, abundant, and affordable shared-IP bandwidth sources with traditional WAN links to create a robust, reliable, high-quality enterprise WAN. With Talari, companies can mix and match different technologies such as MPLS, ATM, Frame Relay and broadband Internet to create an optimized aggregate network that performs much better than the most expensive single network in the mix, but whose weighted average cost is much closer to the least expensive network in the mix.


Designed to bring WAN reliability and higher bandwidth to large data centers and call centers, the 2U rack-mountable Mercury T5000 appliance is offered in two different software configurations:

  • T5000H: designed for large data centers and call centers, T5000H supports aggregation of WAN bandwidth up to 3 Gbps uplink/3 Gbps downlink (3 Gbps full-duplex)
  • T5000L: designed for data centers and call centers, T5000L supports aggregation of WAN bandwidth up to 1 Gbps uplink/1 Gbps downlink (1 Gbps full-duplex)

The upgrade from T5000L to T5000H is a software upgrade, insuring investment preservation. Additionally, T5000 runs the same software as the other models, supporting gigabits of WAN bandwidth across the union of private WAN links and public Internet connections and providing support for a vastly larger number of branch connections and application flows.

Network Control Node (NCN)

Talari T5000 acts as the master controller of the APN and the central point of administration for the client nodes. The NCN's primary purpose is to establish and utilize a Conduit with one or more Talari Client Nodes across the network for enterprise site-to-site communications. A particular NCN can administer and have conduits to multiple Client Nodes.


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 T5000 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.

Geographic Redundancy

With the new Geographic Redundancy feature, an APN Client Node can also function as a secondary Network Control Node. In the event of a primary data center failure, the backup data center should be operational and the secondary Talari appliance would act as the NCN for APN.

Fault Tolerant

Both the T5000H and T5000L appliances include four pairs of fail-to-wire ports, automatically enabling a passive pass-through mode even in case of unforeseen interruptions in an APN device.
