We propose, implement and evaluate three admission models for computational Grids. The models take the expected demand into account and offer a specific performance guarantee. Th...
This paper? provides a description of our Network Time Interface M-Module NTI supporting high-accuracy external clock synchronization by hardware. The NTI is built around our custo...
In a Distributed Database System (DDBS), transactions on objects can be read requests or write requests in a random manner. The replication algorithm of objects critically affects...
We address the problem of processing continuous multi-join queries, over distributed data streams, making use of existing work in the field of publish/subscribe systems. We show ...
