Abstract

Because they avoid extensive redesign of specialized hardware, software-implemented approaches to fault tolerance are very resilient to change. Europe´s Delta-4 project argues persuasively for implementing fault tolerance in a distributed fashion. The Delta-4 approach achieves fault tolerance by replicating capsules/spl minus/runtime representations of application objects/spl minus/on distributed, LAN-interconnected nodes. It can configure capsule groups to tolerate either stopping or arbitrary failures. Its multipoint protocols serve to coordinate capsule groups and for error processing and fault treatment.<>
