We have implemented such a system in Ada 2005 (GNAT Pro). It is presently in the testing phase. The system is more than just DDS, it is a middleware where distribution is one feature among others. Another is device/protocols abstraction. For distribution the middleware supports our proprietary TCP/IP-based protocol. Possibly we also will support our PGM-based (multicast) protocol if there will be demand. For the end devices we support the XCP protocol (both masters and slaves) and the EtherCAT slaves (it is almost ready, now is under test). The middleware is designed for tight real-time constraints. In particular, our customers demand 10kHz sampling and distribution without data loss. Last week we demonstrated such a test setup. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
