DONUT: efficient data localizationHaving a number of copies adapted to the popularity of the data is not enough. It is also necessary to be able to locate the data efficiently. Distributed systems large scale bring together thousands of nodes distributed worldwide. The data is distributed over a logical network according to their identifier. To provide […]

GARGAMEL: improved performance of replicated databases We approach an approach, Gargamel, which consists in serialize upstream transactions that can lead to conflicts, and parallelizing those which are independent.

Our simulations and experiments
