SATURNE is a research project aiming at exploiting as much as possible
the distribution of workstations on LANs in order to increase
fault-tolerance, as well for accidental faults (e.g. harware faults) as
for deliberate faults (e.g. intrusions).
Two main techniques are currently developed in the scope of the Saturne
project :
- To tolerate accidental faults, the SATURATION technique consists in
using idle resources in order to increase the redundancy of active tasks
rather than decrease their response time.
- To tolerate deliberate faults, the Fragmentation-and-Scattering
technique consists in cutting information in small fragments such that
isolated fragments cannot deliver significant information, and in
disseminating those fragments throughout the distributed system. This
technique has been first applied to the design of a secure file archiving
service, and is currently developped for implementation of an
"intrusion-tolerant" network security service.
