Network and Runtime Monitoring in the edutain@grid SOA Alexander Ploß (Universität Münster) This talk will present the edutain@grid project and its relation to network measurement. Developing today's multiplayer online real-time games which support high numbers of users is a challenging task. The edutain@grid project provides a novel system for developing and running Real-Time Online Interactive Applications (ROIA) like fast-paced online computer games or interactive e-learning and training scenarios. This talk will focus on the mechanisms the edutain@grid system utilizes to monitor running ROIA sessions, especially the collection and propagation of network characteristics.
