Searching for methods and ways to transform object-oriented legacy systems into new framework-based applications is the main intention of the ES-PRIT project FAMOOS. The partners involved expect a tremendous increase in software exibility from this approach. This results in the understanding that eeective reengineering of large-scale applications is not(More)
When applying updates on distributed network elements with SDN, intra-update states may violate desired network properties, such as drop- and loop-freeness. Current stateless approaches cannot guarantee the constancy of arbitrary network invariants (correctness) in general, yet update procedures guaranteeing certain invariants do exist. In this paper, we(More)
Updating a network is an essential and continual task in the management of today's softwarized networks. When applying updates on distributed network elements, desired network properties, such as drop- and loop-freeness, might be transiently violated. Although being crucial, update consistency has yet been less considered in network management. In this(More)
Recent years have seen an evolution of SDN control plane architectures, starting from simple monolithic controllers, over modular monolithic controllers, to distributed controllers. We observe, however, that today's distributed controllers still exhibit inflexibility with respect to the distribution of control logic. Therefore, we propose a novel(More)
Land degradation affects large areas of land around the globe, with grave consequences for those living off the land. Major efforts are being made to implement soil and water conservation measures that counteract soil erosion and help secure vital ecosystem services. However, where and to what extent such measures have been implemented is often not well(More)
