The work in this paper is a case study. This paper describes how we are provisioning QoS in a real-time distributed object platform able to support power plant control applications. A previous experiment with a modified Java-ChorusOS-ATM platform based on RM-ODP/ReTINA binding objects enhanced our knowledge on QoS based distributed object systems. RM-ODP/ReTINA brings a distributed object computing model where, time requirements can be specified in terms of QoS parameters. Our goal is to achieve QoS provisioning with off-the-shelf CoS based products in the Real-Time Distributed Object Architectures to be built. Low level building blocks of the architecture as communication networks and operating systems exist as CoS components. The current step of the project deals with distributed object platform selection. But it is not so easy to choose a QoS-enabled middleware.
