Towards Real-Time Fault-Tolerant CORBA Middleware

An increasing number of applications are being developed using distributed object computing (DOC) middleware, such as CORBA. Many of these applications require the underlying middleware, operating systems, and networks to provide dependable end-to-end quality of service (QoS) support to enhance their efficiency, predictability, scalability, and reliability. The Object Management Group (OMG), which standardizes CORBA, has addressed many of these application requirements individually in the Real-time CORBA (RT-CORBA) and Fault-tolerant CORBA (FT-CORBA) specifications. Though the implementations of RT-CORBA are suitable for missioncritical commercial or military distributed real-time and embedded (DRE) systems, the usage of FT-CORBA with RTCORBA implementations are not yet suitable for systems that have stringent simultaneous dependability and predictability requirements. This paper provides three contributions to the study and evaluation of dependable CORBA middleware for performance-se...
