Provisioning QoS in real-time distributed object architectures for power plant control applications

This work is a case study. We describe how we are provisioning QoS in a real-time distributed object platform dedicated to power plant control applications. A previous experiment based on a modified Java-ChorusOS-ATM platform enhanced our knowledge on QoS based distributed object systems. We used RM-ODP/ReTINA as a distributed computing object model where time requirements are specified in terms of QoS parameters. Our goal is to achieve QoS provisioning with off-the-shelf QoS based products in real-time distributed object architectures to be built. Low level building blocks of the architecture as communication networks and operating systems exist as QoS components. The current step of the project deals with distributed object platform selection. It is not so easy to choose a QoS-enabled off-the-shelf middleware.
