Fault tolerance techniques integrating MMS and ISIS

Fault tolerance and interoperability in a heterogeneous environment are two important concerns in distributed industrial applications. The manufacturing message specification (MMS) was designed to standardize and facilitate the remote control and monitoring of industrial devices made by different vendors. Software such as the ISIS Distributed Toolkit makes the task of providing fault tolerance easier for the application programmer. In this paper, we study a realistic, industrial scenario that has been supplied to us by an actual car manufacturing company. We make use of MMS to implement the scenario. Then, we analyze some methods of adding fault tolerance into the scenario by using the ISIS toolkit, as well as other fault-tolerant algorithms on top of MMS. We discuss the results of an actual implementation of these methods and show how the scenario requirements have been satisfied.<>
