.... Topics: Optimizing Middleware for Real time, Determining how to map the results from QoS work at the IPC and OS layers to DOC middleware is currently the focus of many active research projects, such as the DARPA Quorum project [13] the QuO project at BBN [14] and the 2 TAO [15] and TMO [16] projects at Washington University and UC Irvine. One topic of this tutorial, therefore, is to summarize the design techniques and optimization patterns necessary to overcome the historical limitations with middleware described above in order to meet end to end QoS requirements for real time, ....

Timer based invocation capabilities are provided through TAO s Real Time Event Service [6, 9] Where the TMO model creates new ORB services to provide its timebased invocation capabilities [13], TAO provides a subset of these capabilities by extending the standard CORBA COS Event Service. We believe TMO and TAO are complementary technologies because (1) TMO extends and generalizes TAO s existing time based invocation capabilities and (2) TAO provides a configurable and dependable ....

To get an intuitive programming scheme for this synchronization, we want to implement a CORBA service, which automatically synchronizes the period of spontaneous methods with the period of the underlaying timetriggered network. Kim presents in [4] a important fundament for such a programming scheme. ....
