In the first part we discuss SNs fundamentals, presenting a life cycle of SNs that breaks down the creation, implementation, enactment, monitoring and optimization of a network into five distinct phases. Each of these phases interacts with different aspects of the S-Cube research framework. In this deliverable we focus on the initial, modeling and simulation phase of the life-cycle. The second part of the deliverable focuses on the application of simulation techniques to two interrelated types of network analysis: value and performance analysis.

To bring the results together and to provide a coherent view on the different techniques using common realizing architecture a set of integration scenario has been defined and elaborated. Based on the integrated mode l defined in previous documents, these scenarios aim to define the reference architecture and approach relating various contributions, as well as to define the concrete interfaces and dependencies between them. The scenario presented in this deliverable refer to the some of the key research problems studied in the scope of the workpackage and the project, namely cross-layer quality driven monitoring and adaptation, proactive adaptation and context-aware monitoring and adaptation.

Some of the presented contributions validate and extend the S-Cube life-cycle and integrate it with new knowledge about user tasks, inherited from the HCI literature, and context. A special attention is also posed to the problem of service evolution. The various facets of this evolution are considered and a formal framework that allows a definition of service compatibility is provided. A formal framework is also used as the basis for an approach that supports the design and runtime self-adaptation of SBAs. As one of the main goals of industry is to reuse their assets in order not to lose their investments, an important issue for the practical adoption of SBAs is to understand how migration from traditional to SBA systems can be achieved. In this deliverable we present a first step toward a systematization of this field.

Based on the internal validation presented in the deliverable CD-IA-3.2.2 as well on the improvements implemented by the planned readjustment of S-Cube’s Joint Programme of Activities, the research challenges and research questions included in the first version of the IRF (see CD-IA-3.1.3) had been updated with respect to the research focus of the Joint Research Activities. This effort aims at reducing the complexity of the IRF and also to ensure its consistency. In addition, a first attempt to identify the relationship between the research challenges and questions in the IRF and the Future of Internet vision is discussed.

It is an intermediate stage on the research roadmap, starting from issues of local adaptation and self-healing (CD-JRA-2.3.2) to the most complex case involving distributed multi-level adaptation (CD-JRA-2.3.8), where we investigate and integrate certain methods and techniques incrementally. The work is based on and motivated by the antecedent deliverable ''Basic requirements for self-healing services and decision support for local adaptation'' (CD-JRA-2.3.2) and is focused on local adaptation and decision which we consider one of the most important ways to investigate the applicability of certain policies to trigger local adaptation mechanism, and is organized around the general adaptation framework introduced in CD-JRA-2.3.2. Results are presented in 10 published papers that constitute the core contribution of this deliverable. The work is positioned within the Integrated Research Framework (IRF, WP-IA-3.1), internal WP-JRA-2.3 research architecture and overall WP-JRA-2.3 goals and visions.

This progress was focusing on the integration of the different monitoring and adaptation approaches applied by the different layers of the service-based applications. The first integration results cover several aspects of the SBA life-cycle.

All papers deal with the exploitation of codified context knowledge. It can clearly be seen that on the one hand the different research communities interpret “context” differently ranging from HCI aspects to engineering aspects relevant for SBAs. On the other hand our analysis of the relation of the approaches to the life cycle model shows that the approaches try to integrate different phases of the life-cycle and, thus, S-Cube is now focussing more on integrated research, which covers more than one phase of the life-cycle of SBAs.

Application integration serves as a means of developing service-enabled applications based on strategic technology capable of creating and successfully executing end-to-end business processes. The trend will be to move from relatively stable, organization-specific applications to integrated, dynamic, high-value ones where process interactions and trends are examined closely to understand more accurately application needs and dynamics. Such collaborative, complex end-to-end process interactions give rise to the concept of Service Networks (SNs) (see PO-JRA-2.1.1 & PO-JRA-2.1.2). This deliverable targets the concept of a business transaction and explores how transactional processes and process fragments fit in the context of a running scenario which deals with end-to-end processes in a service network that possess transaction properties. Conventional (ACID) and unconventional (application-based) types of atomicity are introduced, including contract, payment and delivery atomicity, in the frame of a business transaction model. The transaction model provides a comprehensive set of concepts and several standard primitives and conventions that can be utilized to develop complex Service-Based Applications (SBAs) involving transactional process fragments No publisher Sammodi Deliverable KeyDeliverable 2010-05-17T14:07:12Z File
