Ebbs & Flows
- Maria Isabel Gandia (CSUC)
Description
Research and Education Networks are probably one of the only places where a network graph can look like it is showing a DDoS attack while it’s not. When you are managing a R&E network, you should not only not stop some gigantic flows, but make your best to let them flow smoothly and without restrictions, in order to make Science progress. Different solutions (like the science DMZ), techniques (like marking packets), and tools (like Scistream) are used to make the network and the analysis of scientific data in nearly real-time more efficient. In this session, we will explore these solutions.
This talk will explore the evolution of the Science DMZ design pattern, including new environments and applications and the value of strategic investments in science-focused high-performance network design. Examples will include Streaming DTNs, Zero Trust, Exascale HPC environments, and workflows which couple experimental and computing facilities together to achieve results otherwise...
Modern scientific instruments generate data at such high rates that online processing is needed for data reduction, feature detection, and experiment steering. These rates also demand memory-to-memory streaming from instrument to remote computer, because local computational capacity is limited and data transmissions that engage file system introduce unacceptable latencies. Such data streaming...
There is a network flow marking effort underway from the High-Energy Physics (HEP) and Worldwide LHC Computing Grid (WLCG) communities. This effort aims to mark packets/flows so they can be correlated with specific research projects. This allows identification of flows for troubleshooting and gives network providers visibility into the research flows they support and allows them to demonstrate...
