The Service Component Architecture (SCA) makes it possible to combine existing and new services based on a variety of technologies with components built using a component-based development approach. However, when asynchronous service compositions are executed, one or more errors can occur, possibly at the same time, affecting the dependability of the composition. To guarantee that the composition succeeds or at least fails in a controlled manner, fault tolerance mechanisms must be employed. In this paper, we propose a novel exception handling model that targets the needs of dependable SCA applications. The model is applicable to service-oriented systems and allows the creation of fault-tolerant asynchronous service compositions. The EH-SCA framework instantiates the proposed model as an extension of the Apache Tuscany SCA infrastructure. Developers can apply this instantiation of the model to both new and existing applications by using a simple and flexible aspect-oriented programming model. Finally, a case study of the EH-SCA framework shows how it can be used to build dependable distributed applications.

Computer perception of real-life situations is performed using a variety of recognition techniques, including video-based computer vision, biometric systems, RFID devices and others. The proliferation of recognition modules enables development of complex systems by integration of existing components, analogously to the Service Oriented Architecture technology. In the paper, we propose a method that enables integration of information from existing modules to calculate results that are more accurate and complete. The method uses semantic description of concepts and reasoning to manage syntactic differences between information returned by modules. The semantic description is based on existing real-world concepts in video recognition and ubiquitous systems. We propose helper functionalities such as: module credibility rating, confidence level declaration and selection of communication protocol. Two integration modes are defined: voting of matching concepts and aggregation of complementing concepts.

“…The multi-version concept, which was used earlier only as a methodology for reducing design faults, has been expanded and united in the triad "multi-version systemstechnologies -projects." 11 Dependability attributes depend on both system components' (products) properties and development processes' properties, so the multi-version approach is aimed at all aspects.…”

This article analyzes the approaches related to dependable computing systems and Force Information Infrastructure creation out of undependable components (systems). Taxonomies of dependable systems and stages of dependable systems paradigms evolution are discussed. A life-cycle model and principles of development and assessment of dependable systems by means of multi-version technologies are considered. Some general tasks and methods for providing and managing dependability are analyzed. The Models, Techniques and Tools Infrastructure for supporting transformation of the Force Information Infrastructure is proposed. Warfighter Information Network (WIN) development is considered in this article as an example of the principles of using dependable computing systems implementation to support transformation of the Force Information Infrastructure.
