This TAO Workshop presentation will discuss the design, implementation, and performance of the University of Rhode Island (URI) Real-Time Distributed Object Computing group’s Static Scheduling Service, and Real-Time Binding Service.
The Static Scheduling Service is an implementation of the Real-Time CORBA 1.0 (RTC1) Scheduling Service standard. The Real-Time Binding Service is an implementation of the standard CORBA Trader Service. We assume a TAO Workshop audience that is familiar with TAO and CORBA, but not necessarily with RTC1 and the details of the RTC1 Scheduling Service. The workshop presentation will provide a brief background on the RTC1 features that impact the Static Scheduling and Real-Time Binding Services, as described in Section 2. The presentation will use as an illustrative example our integration of the Static Scheduling Service and Real-Time Binding Service into the Unmanned Arial Vehicle (UAV) Open Experimental Platform (OEP) that has been produced by BBN, as described in Section 3. We will show how both the Static Scheduling Service and the Real-Time Binding Service work, including internal UML diagrams, and sample configuration files that are at the heart of their implementations, as described in Sections 4 and 5. We expect that by the TAO Workshop date these services will have been committed to the TAO Repository; it will be these committed services that we describe. We will conclude with performance results for the services in the UAV application using common metrics derived on the DARPA PCES program, as described in Section 6. If time permits, we will show how these static services lead to our current work on Dynamic Distributed Scheduling and Binding Services, as described in Section 7.
