Motivation, problem area
• Interactive real-time applications, either for soft or hard real-time, require strong QoS guarantees
• Nowadays, RT is only achievable through distinct hardware and software
• IRMOS strives to combine Service Oriented Infrastructures (SOIs) with real-time applications

Research Objectives
• How to combine RT and SOI (Virtualisation)
• SLA Management Framework covering the complete value chain
• Mapping of high-level application parameters to low-level resource provision attributes
• Validation through application scenarios

Research approach, Methodology
• Using applications as an example for the requirements
• Virtual and augmented reality as a scenario using the COVISE (COllaborative VIsualization and Simulation Environment) software
• Identification of actors in the value chain (IRMOS, ISONI, …) for the scenario
• Identification of use cases for the scenario

Major Outcomes/Results
• One SLA is not enough: identified different types of SLAs• Each SLA corresponds to one contact point between actors
in the value chain

Major Outcomes / Results II
• Union of SOI and RT offers major business benefits
• Usability for other scenarios, e.g. where– massive collaboration with real-time constraints is expected, such
as e-learning applications with high numbers of users interacting with the application and with other users;
– high volumes of data need to be processed, supporting real-time interaction with end users, such as film post-production applications.

Conclusion and outlook
• Distinct contracts depending on the actors (A-SLA, T-SLA) necessary
• Enhancing SOI with RT is a novel approach
• It‘s challenging but possible
• Implementation is performed now for the first demonstrator (finished in Feb. 2010)
