Abstract
Future NASA Earth science missions, including the Earth Observing Systems (EOS), will generate vast amounts of data that must be processed and stored at various locations around the world. This article presents a stepwise-refinement of the Intelligent Database Management (IDM) system of the Distributed Active Archive Center (DAAC-one of seven regionally-located EOSDIS archive sites) architecture to showcase the telecommunications issues involved. This architecture is developed into a general overall design. It is shown that the current evolution of protocols is sufficient to support IDM at Gbps rates over large distances. It is also shown that the network design can accomodate o flexible data ingestion storage pipeline and a user extraction visualization engine, without interference between the two.
