ACE/TAO is an Open Source implementation of the OMG Real-Time CORBA Specification and might fill this gap. It is designed platform independent, implemented in C++ and provides a standardized communication framework. Real-Time CORBA is already used in industrial environments, e.g. aircraft, naval equipment and others. This paper explains the basics of the ACE/TAO framework and its usage in industrial communication. On the basis of a real-world example - transmission of an 1 KiB data frame - two communication methods are evaluated: the RT-CORBA Remote Procedure Call and the TAO Real-Time Event-Channel. The performance measurement methods are explained in detail. Measurement results under various system loads and a comparison of ACE/TAO on top of a vanilla Linux kernel and a RT\_PREEMPT enabled Linux kernel provide a meaningful insight in the capabilities of RT-CORBA. Finally, the paper provides an analysis of functionality which needs to be improved in the operating system to provide real deterministic communication through a standardized framework. +\end{abstract} + +\vspace{10mm} + +\begin{multicols}{2} + +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +%% SECTION (REQUIRED) +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +\section{ACE/TAO Basics} +ACE is an open-source c++ framework for platform-independent system- and network-programming.
