DFT / HA Core

The Distributed Fault-Tolerant/High-Availability (DFT/HA) core software functionality allows the creation and management of:

  • Distributed Fault-Tolerant applications
  • Pure Distributed applications
  • Pure Fault-Tolerant applications

For Distributed Fault-Tolerant applications, illustrated in Figure 1, the DFT/HA Core software distributes the protocol load onto available physical processors; dynamically re-distributes the load on processor failure and new processor introduction; retains active calls and recovers from processor failure; and allows maintenance operations to be performed without bringing the system down.

Figure 1: Distributed Application

For Pure Distributed applications, the DFT/HA Core software distributes the protocol load on available physical processors and dynamically re-distributes the load on processor failure and new processor introduction.

For Pure Fault-Tolerant applications, illustrated in Figure 2, the DFT/HA Core software can be used to build an active/standby redundant system. The core software manages system operations, retains active calls on processor failure, and allows maintenance operations to be performed without bringing the system down.

DFT/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 DFT/HA applications

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