An approach for adaptive fault-tolerance in object-oriented open distributed systems

Effective fault-handling in emerging complex distributed applications requires the ability to dynamically adapt resource allocation and fault-tolerance policies in response to possible changes in environment, application requirements, and available resources. The paper reports an effort on design and implementation of an adaptive fault-tolerance middleware (AFTM) using a CORBA-compliant object request broker resting on the Solaris open system platform. The paper also briefly discusses the essential capabilities of AFTM, the overall system architecture, and its design decisions.
