AbstractMany mission critical applications are required to meet high degrees of simultaneous dependability and predictability requirements. The OMG's Fault-tolerant (FT) CORBA and Real-time (RT) CORBA help developers to manage applications' dependability and predictability requirements in isolation. It is still not possible to use CORBA to manage applications' FT and RT properties in unison due to contradicting strategies in the support mechanisms. This project will investigate how to reconcile the incompatibilities between the two specifications and to provide a design that simultaneously supports CORBA applications with both FT and RT properties. By developing a fault-tolerant, real-time CORBA Naming Service, we will explore mechanisms for implementing predictable FT mechanisms and evaluate strategies for specifying applications' FT and RT requirements. The Phase~I project will focus on addressing design issues in FT supporting mechanisms to eliminate non-deterministic behaviors, as well as benchmarking their performance with integrated FT/RT supports.
