The latest version of Real-Time CORBA defines a Distributable Thread primitive to support real-time computing in a dynamic distributed environment. However, this standard does not provide support for making and enforcing global decisions. This paper dfescribes the framework for a Distributed Scheduling Service (DSS) that provides globally sound decision-making and scheduling enforcement to a real-time distributed system. The paper describes the design and implementation of the framework as well as preliminary performance results.
