Evaluating policies and mechanisms to support distributed real-time applications with CORBA

摘要

To be an effective platform for performance-sensitive real-time systems, commodity -off-the-shelf (COTS) distributed object computing (DOC) middleware must support application quality of service (QoS) requirements end-to-end. However, conventional COTS DOC middleware does not provide this support, which makes it unsuited for applications with stringent latency, determinism, and priority preservation requirements. It is essential, therefore, to develop standards-based, COTS DOC middleware that permits the specification, allocation, and enforcement of application QoS requirements end-to-end.
