Recent project outcomes Seven new public deliverables have been finalized during the period September 2008 to beginning of February 2009. Seven public deliverables have been finalized since the latest Newsletter issue (September 2008 to beginning of February 2009): D2.4.1 Security requirements Analysis Report. Released in November 2008, this document aims to identify the set of security requirements and the security model of the IRMOS platform. In particular, D2.4.1 focuses on security related requirements for the selected IRMOS reference applications: film postproduction, e-learning, virtual and augmented reality. This report provides the input necessary to the IRMOS design and development work packages. It is within these work packages that the decisions will be made on which of the requirements to satisfy at both on architectural and implementation level. D3.1.2 IRMOS Overall Architecture. This deliverable has been released beginning of February 2009. The work described in the report was carried out in WP3 - IRMOS Platform Specification - and provides the analysis, design and specification of the architecture of the IRMOS platform. This is the second of four reports in WP3 that describe, in increasing levels of detail, the functionality of the IRMOS platform in terms of the capabilities, the individual components and their interactions. It is a self-describing document that continues the work of WP3 presented in the previous public deliverable, D3.1.1. During project months 8 to 12, WP3 exploited the updated user requirements, the IRMOS value chain analysis results and security requirements, the application scenarios and the outputs of the technical WPs (internal documents, outcomes of meetings, deliverables) and produced a complete report on the overall IRMOS platform architecture that explains the functionality of all building blocks of the platform and also covers the real-time, virtualization, business and security aspects of the project. The output of WP3 is of high importance for the other WPs but also for the project itself, since these reports include the guidelines for developers to implement their components, associating, on the same time, the user s requirements and the scenarios with specific functionalities and building blocks. D4.1.1 Definition and implementation of the three scenarios and its real-time requirements. This deliverable was released beginning of February 2009. It aims to identify the application scenarios which benefit from the innovations of the IRMOS platform and to point out their real-time requirements. Three scenarios from different business sectors were chosen to proof the concepts and innovative technologies developed within the IRMOS project: o o o Digital film postproduction Virtual and Augmented reality E-learning IRMOS Newsletter Issue N 2 8
These applications were analyzed based on the results of the D2.1.1 Initial version of requirements analysis report, and with consideration of the main two IRMOS principles, Service Oriented Infrastructure and real-time functionality. Next to the definition of application scenarios and their demonstrations, this deliverable provides initial ideas how to realise the implementation of the service oriented applications. So this deliverable offers extremely valuable input for all technical work packages and especially for the demonstrator work package. D5.1.1 Models of real time applications on service oriented infrastructures. This deliverable was released beginning of February 2009. It considers the value-chain for real-time applications hosted by third-party service providers. In the context of this value chain, we analyse who might benefit from the use of models, how and why these models might be used, and when during the application lifecycle modelling is most useful. Techniques are presented for building models of real-time applications including the use of stochastic process algebras, finite state automata, workflow models (e.g. BPEL, BPMN and YAWL) and specification languages (e.g. UML MARTE). The report discusses how these models need to be supported by estimation of application resource consumption, e.g. through benchmarking and fitting, and how mapping techniques allow models to be built for different actors in the value chain, e.g. for application providers and infrastructure providers. Tool support is also discussed e.g. PRISM for probabilistic model checking and Visual Service Composition Studio for service-oriented modelling. A detailed and specific real-time application scenario is included and modelled to allow the various techniques presented in this document to be demonstrated and quantitatively evaluated. D6.4.1 Initial version of Real-time architecture of EE. Released end of January 2009, this document provides an overview of how real-time service guarantees will be provided within the IRMOS platform and architecture. Even if the overview generally spans across the multiple technological areas of processing, storage and networking, the focus is primarily on the first one. The other two areas will be covered in further deliverables, that will deal with QoS aware storage and QoS support at the network level). Specifically, the document focuses on issues related to the provisioning, within an IRMOS Execution Environment (EE), of appropriate performance guarantees to concurrently running Service Components (SCs). The discussion spans from the motivations at the base of the need for mechanisms that ensure predictable scheduling of the available computing elements within an EE, as driven by the performed requirements analysis, to the technical details about how such mechanisms may be provided within the project, along with what are the research challenges arising from the intermixing of virtualization and real-time.

D7.1.1 ISONI addressing schemes. This deliverable was released end November 2008. The IRMOS framework aims at enabling infrastructure providers to offer hosting for real-time-capable and highly customizable services. To cut costs, the infrastructure is shared among multiple customers, giving each exclusive access to a virtual environment. In the context of this deliverable, an addressing scheme that supports the isolation of applications that are deployed to the IRMOS framework on the level of the Intelligent Service Oriented Infrastructure (ISONI) has been developed. Basically, this is done by transparently adding namespace information to each executed application, which is described as a so-called Virtual Service Network. D9.1.1 Project Web site and Project Presentation. A short report corresponding to this deliverable was released beginning of November 2008. However, an initial website was activated at the very start of the project in order to provide the project with public visibility. This has evolved to meet the changing needs of the project and will be continuously updated as a result of user feedback and to facilitate future utilization both internally within the consortium and externally to potential users and stakeholders. A general project presentation has been available at the beginning of the project in order to allow all IRMOS partners to present a consistent overview of the project in the events they are attending. All IRMOS public deliverables are available in http://www.irmosproject. eu/deliverables/ We will continue working with enthusiasm and producing new interesting results. Until our next Newsletter!
