Many important cloud services require replicating massive data from one datacenter (DC) to multiple DCs. While the performance of pair-wise inter-DC transfers has been much improved, prior solutions are insufficient optimize bulk-data multicast, as they fail explore rich overlay paths that exist in geo-distributed DCs, well remaining bandwidth reserved for online traffic under fixed separation ...

Data grid is a distributed collection of storage and computational resources that are not boundedwithin a geophysical location. It is a fast growing area of research and providing efficient data access andmaximum data availability is a challenging task. To achieve this task, data is replicated to different sites. A number of data replication techniques have been presented for data grids. All re...

Research data are often released upon journal publication to enable result verification and reproducibility. For that reason, research dissemination infrastructures typically support diverse datasets coming from numerous disciplines, tabular program code audio-visual files. Metadata, or about data, is critical making outputs adequately documented FAIR. Aiming contribute the discussions on devel...
