+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\begin{abstract}
+Automation technology lacks an established platform independent, high-level, object oriented real-time capable communication standard, which is based on standard Ethernet hardware and drivers. 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.

+\section{ACE/TAO Basics}
+ACE is an open-source c++ framework for platform-independent system- and network-programming. TAO is a Real-time CORBA implementation build on top of ACE.
+
+As shown in figure X, the key features of a Real-time capable ORB are: locating objects in constant time, preallocation of resources, operating system independent priority handling, priority based scheduling.
