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.

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.

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