Abstract

There is increasing demand to extend Object Request Broker (ORB) middleware to support applications with stringent quality of service (QoS) requirements. However, conventional ORBs do not define standard features for specifying or enforcing end-to-end QoS for applications with deterministic real-time requirements. This paper describes the design and performance of a real-time I/O (RIO) subsystem optimized for QoS-enabled ORB endsystems that support high-performance and real-time applications running on off-the-shelf hardware and software. The paper illustrates how integrating a real-time ORB with a real-time I/O subsystem can reduce latency bounds on end-to-end communication between high-priority clients without unduly penalizing low-priority and best-effort clients.
