Trillium | PSF - MTP Level 3 (FT/HA)

Description

The Protocol-Specific Function (PSF) for the Message Transfer Part - Level 3 (MTP3) Fault-Tolerant/High-Availability (FT/HA) software enables MTP3 to execute in pure fault-tolerant (active/standby) and distributed fault-tolerant (N active * M standby) systems. PSF - MTP3 updates the standby copy with state changes from the active copy. In case of failure, the standby copy can assume operations with minimal disruption in the system.

Trillium PSF - MTP3 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 MTP3 applications

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

Features + Benefits

Provides a command interface to activate a resource set and to warm start a resource set.
Supports the operator-initiated switchover allowing for the standby node to become active, and vice versa (controlled switchover), preventing the loss of states.
Supports the switchover of the standby to the active upon failure (forced switchover). It brings the protocol database and system into a consistent state, after a forced switchover of the master critical resource set, and resumes operations.
Supports run-time state updates to keep the standby MTP3 synchronized with the active MTP3.
Stops sending state updates to the standby when it becomes OOS
Supports the warm start of the peer resource set to make it standby from the OOS state. PSF - MTP3 does not delay data traffic processing during the warm start operation.
Enables the MTP3 software to handle protocol events for a resource set during the warm start of that particular resource set.
Enables the MTP3 instance to handle protocol events for other resource sets assigned to it, during the controlled switchover of one resource set.
Performs operations simultaneously, such as warm start and peersync, on multiple resource sets.
Supports the forced switchover when the active resource set assigned to the MTP3 instance becomes OOS.
Provides a shutdown procedure that resets the PSF - MTP3 states and de-allocates the memory allocated by PSF - MTP3 for its operation up to the time of the shutdown.
Generates alarms to the layer manager upon finding failures during the PSF - MTP3 operation.
Generates debug prints if enabled by the layer manager.
Provides a command interface to abort an ongoing warm start state update or controlled switchover state update.
Provides mechanisms to detect the synchronization loss between the active and standby copies of the resource set.
Provides the Heartbeat mechanism to detect communication loss between copies when updates do not occur.
The PSF - MTP3 software works with all the options supported by Trillium MTP3 software.
Supports the Rolling Upgrade feature to upgrade the software which allows upgrading a system to a new version of the software without taking the system offline or interrupting service.
Conforms to Trillium Advanced Portability Architecture (TAPA)

Product Interworking

PSF - MTP3 (FT/HA) interworks with Trillium MTP3 protocol, protecting it from failure, the Fault-Tolerant/High-Availability (FT/HA) Core software and the Distributed Fault-Tolerant/High-Availability (DFT/HA) software.

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