  1. Technical Concertation Meeting Vision, Challenges and Outcomes Dimosthenis KyriazisNational Technical University of Athens dkyr@telecom.ntua.gr

  2. At a Glance • Duration • 36 months (Started on February 2008) • Effort • 1.133 PM • Budget • Total Cost: 12,6 M€ • EC funding: 7,9 M€, under FP7, ICT-2007.1.2 Service and Software Architectures, Infrastructures and Engineering • Consortium • 11 partners from industry and academia belonging to 6 European countries (DE, UK, GR, IT, NO, ES) Technical Concertation Meeting

  3. Vision • A Service Oriented Infrastructure, which allows the adoption of interactive real-time applications • To make it feasible we have a set of challenges to face: • Enabling real-time attributes at various levels of the infrastructure (network, storage, processing, application, business) • QoS Guarantees • Automated SLA Negotiation • Mapping between high-level application terms and fine-grained resource-level attributes • Specification Languages to describe real-time applications • ... Technical Concertation Meeting

  4. The IRMOS SOI Technical Concertation Meeting

  5. Application Control • Adaptation and Integration of the applications in the IRMOS SOI • Tools to design workflows and services that have measurable and predictable behaviour • Mechanisms to identify critical interdependencies and resources that can lead to bottlenecks in order to improve service performance • Specification language and tools for generating code artefacts to aide application adaptation and integration Technical Concertation Meeting

  6. Framework Services • Software and techniques to support real-time applications • Set of services • Workflow Management • Mapping • SLA Management • Discovery • Monitoring • Data Management • ... • Modelling, Analysis and Planning (MAP) environment to: • Estimate and optimise resource provisioning needs necessary to enact a workflow according to SLA guarantees • Estimate service performance and responsiveness • Discover exceptional behaviour that is likely to break QoS guarantees Technical Concertation Meeting

  7. Intelligent Service Oriented Network Infrastructure • Intelligent Networking • Network topology hiding by virtualization • Allocation of link resources and provisioning of connectivity • Sustaining individual QoS guarantees for co-existing services on a shared transport medium • Supervision and monitoring. • Execution Environment • Consolidation of the infrastructure and its services • Live migration of services between Execution Environments • Methods for temporal (timely scheduling) isolation between services running on different shares of a resource • Integration of processing and storage resources Technical Concertation Meeting

  9. QoS & SLAs • Specific Topics • Ease of use through abstraction • mapping between high-level application terms and fine-grained resource-level attributes • Business Objectives and Relationships • mapping between business-level objectives to resource management policies and vice versa • Automated SLA negotiation and monitoring at various levels including the Network level • Adaptive QoS control mechanisms for appropriate use of redundancy in resource allocations • QoS on Storage: Storage units with response / processing time aspects Technical Concertation Meeting

  10. Main Outcomes • IRMOS Toolbox • set of tools, guidelines and best practises to enable the creation and deployment of real-time interactive applications on SOIs • Software tools and modelling environments • allow for real-time interactive applications to be written to target the IRMOS framework • Specification languages • unify various parameters and characteristics for the description of real-time applications on SOIs. Technical Concertation Meeting

  11. Demonstrators • Collaborative Digital Film Postproduction • Virtual and Augmented Reality • Interactive collaborative e-learning Technical Concertation Meeting 11
