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

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, M ethodology 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

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 O utcomes /Results One SLA is not enough: identified different types of SLAs Each SLA corresponds to one contact point between actors in the value chain IRMOS Project, D7.2.1 Initial version of Path Manager: Architecture, ALUD and other partners, May 2009

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)
