dc.description.abstractThis paper presents a new service for CORBA applications that orchestrates the timely execution of the tasks of a distributed real-time system in a flexible way. It follows the CORBA philosophy of complementing the CORBA standard with additional services that solve specific problems and facilitate using CORBA in complex applications. The service has been designed for highly coupled applications that execute over LANs. It provides a synchronous framework to synchronize distributed applications that is open to accepting and removing components on-line, with reduced impact on the application timing. It also provides the flexibility to use different distributed scheduling policies that can override the local operating systems schedulers. This paper describes the service architecture and implementation as well as its best-case performance on low computing power hardware with the QNX OS and connected to a switched Ethernet network. Finally the usage and of the service is illustrated with one case study: the synchronization of several robots in a welding process.en
dc.description.sponsorshipIsidro Calvo received his BsC in Physics, and his MsC and PhD in Control Engineering from the University of the Basque Country (UPV/EHU) in 1993, 1994 and 2004, respectively. He joined the UPV/EHU in the year 2000 as a lecturer. Currently, he is an associate professor at the Automatic Control and Systems Engineering department of the same University. Formerly, he worked as a software engineer in a data acquisition company. He has participated as a researcher of several research projects funded by the National and European R&D programs. His research interests include middleware technologies, real-time networks and distributed industrial/embedded systems. This work has been supported in part by the ARTEMIS JU through the CRAFTERS project (grant no. 295371 ), by the Spanish Ministry of Economy and Competitiveness (MINECO) under project DPI2012-37806-C02-01 and by the University of the Basque Country (UPV/EHU) through grants EHU13/42 and UFI11/28 .
