Trillium | Fault-Tolerant/High-Availability (FT/HA) Core

Description

The Fault-Tolerant/High-Availability (FT/HA) Core portable software product enables mission-critical applications to employ an Active/Standby architecture for High Availability systems. FT/HA Core is independent of the underlying application and may be used with any Trillium protocol layer or stack.

FT/HA Core software enables telecom equipment manufacturers of soft switches, signaling gateways, signal transfer points, service control points, media gateway controllers or other products to:

• Accelerate time to market
• Reduce development costs
• Reduce project risk of internally developed FT/HA applications

A series of technology-specific products, each called a Fault-Tolerant/High-Availability Protocol Specific Function (FT/HA PSF), is used to update the states of the Standby side from the Active side. As shown in the figure below, in case of a failure the Standby can resume operation with minimal service disruption. Refer to the FT/HA PSF data sheet covering the protocol of choice.

Fault-Tolerant Application, SS7 Stack

Product deliverables consist of C source software, documentation, training, a warranty and technical support.

Features + Benefits

• Supports protection of single-layer as well as multi-layer applications.
• Maintains active connections during software or hardware failures.
• Supports Controlled Switchover for operator-initiated maintenance procedures without loss of information.
• Supports Forced Switchover when the Active side fails.
• Supports Warm Start of the Standby and causes no delay processing data traffic during the Warm Start operation
• Supports integration with the customer's fault-tolerant layers via a well defined API
• Supports software upgrades using the Rolling Upgrade Feature. This feature allows upgrading to a new version of the software without taking the system offline or interrupting service.
• Conforms to Trillium Advanced Portability Architecture (TAPA)
• Benefits of licensing Trillium software from Continuous Computing

Product Interworking

FT/HA Core software directly supports Trillium software products that must be protected from failure.

Continuous Computing also offers Trillium Professional Services to integrate Trillium software into customers' products.

See the Distributed Fault-Tolerant/High Availability (DFT/HA) Core datasheet for information concerning distributed implementations.
