Integrated Environment for Reliable Systems

Objectif

The CONCORDIA project aimed to provide an environment which integrated a set of hardware and software mechanisms and components in order to facilitate the construction and support the operation of reliable distributed application systems based on local area networks.
The architecture was intended to provide a programming model integrating the communication needs of distributed software with the various mechanisms required for fault tolerance.
The model was to allow the construction of fault-tolerant systems based on the concept of active stand-by, with software redundancy supported by hardware redundancy in the network.

The model was to allow the construction of fault tolerant systems based on the concept of active stand by, with software redundancy supported by hardware redundancy in the network. The project completed system architecture and demonstration task specifications. The environment provides a computational model in which objects communicate by means of remote operations calls. Objects are replicated at different nodes of the system for backup in the event of a node failure. Checkpointing is invoked automatically during the remote operations calls, thus ensuring that a backup object will start executing from a known state in the event of a failure.

Exploitation
The results of the project were used in project 818, DELTA-4.
