We describe a software architecture for storage services in computational grid environments. Based upon a lightweight message-passing paradigm, the architecture enables the provision and composition of active, distributed storage services. These services can then cooperatively provide access to distributed storage in a manner potentially optimized for dataset and resource environments. We repor...

A component framework is based on a software architecture, a set of components and their interaction mechanisms. This thesis examines the componentbased software development by reviewing the requirements for a component framework development, proposing a model of a component framework of a distributed control systems family and demonstrating results with cases drawn from the control systems fam...

The goal of software architecture optimization is to find architecture candidates that satisfy the expectations of all relevant stakeholders with regard to some quality attributes, e.g., performance, modifiability, or reliability. Quality attributes usually compete with each other, which makes trade-offs inevitable. In the SQuAT project the suitability of distributed search strategies for archi...

This paper describes an approach to designing self-healing component for robust, concurrent and distributed software architecture. A self-healing component is able to detect object anomalies inside of the component, reconfigure inter-component and intra-components before and after repairing the sick object, repair it, and then test the healed object. For this, each self-healing component is str...

As software systems become larger and more decentralized, increasingly cross organizational boundaries and continue to change, traditional structural and prescriptive software architectures are becoming more rulecentric for better accommodating changes and regulating distributed design and development processes. This is particularly true for Ultra-Large-Scale (ULS) systems and industry-wide ref...

This paper proposes an alternative architecture for the implementation of Software Defined Radio (SDR) systems, providing low-cost, high degree of flexibility and scalability. The architecture is based on a cluster of COTS (Commercial Off-The-Shelf) computers interconnected by standard network devices (LAN network interface cards and switches). This architecture is mainly intended for testing s...

Distributed Feature Composition (DFC) is a new component-based architecture for telecommunication services. Its principles are similar to the well-known pipe-and-filter architecture, adapted for use in the telecommunication domain. We present an overview of this architecture and explain how it might be used as a basis for componentbased development of telecommunication software. We also describ...

Dependable LQNS is a software tool for modeling and evaluating performability of fault-tolerant layered distributed applications that use a separate architecture for failure detection and reconfiguration. It takes into account the effects of management architecture, application software architecture, failure of management and application components in the dependability computation. It uses a co...
