Vision
A Service Oriented Infrastructure, which allows the adoption of interactive real-time applicationsTo 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 GuaranteesAutomated SLA NegotiationMapping between high-level application terms and fine-grained resource-level attributesSpecification Languages to describe real-time applications...

Application Control
Adaptation and Integration of the applications in the IRMOS SOITools to design workflows and services that have measurable and predictable behaviourMechanisms to identify critical interdependencies and resources that can lead to bottlenecks in order to improve service performanceSpecification language and tools for generating code artefacts to aide application adaptation and integration
*



Framework Services
Software and techniques to support real-time applicationsSet of servicesWorkflow ManagementMapping SLA ManagementDiscoveryMonitoring Data Management...Modelling, Analysis and Planning (MAP) environment to:Estimate and optimise resource provisioning needs necessary to enact a workflow according to SLA guaranteesEstimate service performance and responsivenessDiscover exceptional behaviour that is likely to break QoS guarantees
*



Intelligent Service Oriented Network Infrastructure
Intelligent NetworkingNetwork topology hiding by virtualizationAllocation of link resources and provisioning of connectivity Sustaining individual QoS guarantees for co-existing services on a shared transport mediumSupervision and monitoring.Execution EnvironmentConsolidation of the infrastructure and its servicesLive migration of services between Execution EnvironmentsMethods for temporal (timely scheduling) isolation between services running on different shares of a resourceIntegration of processing and storage resources

QoS & SLAs
Specific TopicsEase of use through abstractionmapping between high-level application terms and fine-grained resource-level attributesBusiness Objectives and Relationshipsmapping between business-level objectives to resource management policies and vice versaAutomated SLA negotiation and monitoring at various levels including the Network levelAdaptive QoS control mechanisms for appropriate use of redundancy in resource allocationsQoS on Storage: Storage units with response / processing time aspects
*



Main Outcomes
IRMOS Toolboxset of tools, guidelines and best practises to enable the creation and deployment of real-time interactive applications on SOIsSoftware tools and modelling environments allow for real-time interactive applications to be written to target the IRMOS frameworkSpecification languages unify various parameters and characteristics for the description of real-time applications on SOIs.
