Title: Global Petascale to Exascale Workflows for Data Intensive Science Accelerated by Next Generation Programmable SDN Architectures and Machine Learning Applications
Lead: Harvey Newman (Caltech)
Abstract: The demonstration includes several of the latest major advances in software defined and Terabit/sec networks, intelligent global operations and monitoring systems, workflow optimization methodologies with real-time analytics, and state of the art long distance data transfer methods and tools and server designs, to meet the challenges faced by leading edge data intensive experimental programs in high energy physics, astrophysics, climate and other fields of data intensive science. The key challenges being addressed include: (1) global data distribution, processing, access and analysis, (2) the coordinated use of massive but still limited computing, storage and network resources, and (3) coordinated operation and collaboration within global scientific enterprises each encompassing hundreds to thousands of scientists.
AmLight Express and Protect (AmLight-ExP) (NSF Award #1451018) has been supporting the LSST, LHC, and many high-throughput low latency experiments using a Software-Defined Networking (SDN) that includes the new Monet submarine cable and a 100G ring network. The AmLight SDN was built to enhance collaboration, research, and education between the U.S. and South America.

Title: Big Data Express project demonstration
Lead: Wnedji Wu (Fermilab)
Abstract: Big data has emerged as a driving force for scientific discoveries. To meet data transfer challenges in big data era, DOE’s Advanced Scientific Computing Research (ASCR) office has funded the BigData Express project ( BigData Express is targeted at providing schedulable, predictable, and high-performance data transfer service for DOE’s large-scale science computing facilities and their collaborators. In this demo, we use BigData Express software to demonstrate bulk data movement over wide area networks. The following features in BigData Express will be demonstrated:

  • A peer-to-peer, scalable, and extensible model for data transfer services;
  • A visually appealing, easy-to-use web portal;
  • A high-performance data transfer engine;
  • Orchestrating and scheduling of system (DTN), storage, and network (SDN) resources involved in the file transfers.
  • On-Demand provisioning of end-to-end network paths with guaranteed QoS;
  • Robust data transfer services provisioning through strong error handling mechanisms;
  • Safe and secure data transfer services by using multiple security mechanisms;
  • The interoperation between BigData Express and SENSE;
  • Integration of BigData Express with scientific workflows.

The demonstrations and presentations are a collaborative effort from the following participating institutions:
California Institute of Technology (Caltech: High Energy Physics (HEP), Laser Interferometer Gravitational-Wave Observatory (LIGO), The Large Synoptic Survey Telescope (LSST), Caltech: Information Management Systems & Services (IMSS)), University of Southern California (USC), Florida International University (FIU), USC Information Sciences Institute (ISI), Georgia Institute of Technology (GeorgiaTech), Yale University, IBM, University of Maryland, Virnao, San Diego Supercomputer Center (SDSC), University of California San Diego (UCSD), Pacific Research Platform (PRP), Massachusetts Institute of Technology (MIT) , Energy Sciences Network (ESnet), National Energy Research Scientific Computing Center (NERSC), Lawrence Berkeley National Laboratory (LBNL), São Paulo State University (UNESP), Starlight Internet2, Johns Hopkins University, SURFnet, Fermi National Accelerator Laboratory (Fermilab), Argonne National Laboratory, University of Michigan, Northeastern University, Colorado State University, Tennessee State University, University of California Los Angeles (UCLA), Tata Institute of Fundamental Research (TIFR Mumbai), Corporation for Education Network Initiatives in California (CENIC: Pacific Wave), Academic Network at São Paulo (ANSP Brazil), National Education and Research Network (Rede Nacional de Ensino e Pesquisa – RNP), National University Network (Red Universitaria Nacional – REUNA Chile), Ciena.

About the SC Conference Series
Established in 1988, the annual SC conference continues to grow steadily in size and impact each year. Approximately 5,000 people participate in the technical program, with about 11,000 people overall.
SC has built a diverse community of participants including researchers, scientists, application developers, computing center staff and management, computing industry staff, agency program managers, journalists, and congressional staffers. This diversity is one of the conference’s main strengths, making it a yearly “must attend” forum for stakeholders throughout the technical computing community.
The technical program is the heart of SC. It has addressed virtually every area of scientific and engineering research, as well as technological development, innovation, and education. Its presentations, tutorials, panels, and discussion forums have included breakthroughs in many areas and inspired new and innovative areas of computing. (

SubOptic Conference 2019

The AmLight team presented the collaborative paper “Mitigating soft failures using network analytics and SDN to support distributed bandwidth-intensive scientific instruments over international networks” at the SubOptic Conference 2019. The conference was held in New Orleans, LA on 8-11 April 2019. A triennial event, SubOptic is the longest running and most comprehensive conference series in the world for the submarine fiber industry.

Abstract:  With the consolidation of high-speed networks and worldwide scientific deployments, new experiments are being conducted remotely. The control and data gathering of these bandwidth-intensive mission-critical instruments require a reliable network infrastructure capable of reacting in real-time to soft failures, such as packet loss. To address the mission-critical real-time instruments’ Service Level Agreement (SLA), streaming telemetry and data-driven analytics are required. In recent years, the industry has created many open consortiums and specifications, such as OpenConfig and Inband Network Telemetry (INT). As a result, we have new levels of interconnections, interoperation, and disaggregation allowing Software-Defined Networking (SDN) applications to use protocol agnostic, common APIs, Artificial Intelligence and Machine Learning to create reliable and adaptive networks. This paper aims to present the ongoing effort to create an adaptive network infrastructure capable of identifying and isolating soft failures in an automated approach to optimize bandwidth-intensive data transfers. Our approach leverages the most recent solutions offered by the optical and packet layers using SDN and network analytics.

Global 100G session at I2 Global Summit 2019

Highlights of the AmLight project were presented at Global 100G session at the Internet2 Global Summit on March 7 along with projects from ANA-100G, GÉANT, RedCLARA/RNP, and SINET. The session highlighted breakthrough initiatives enabling the first 100G research and education network around the world, pushing for greater connectivity around the globe. Efforts stemming from the Global Network Architecture (GNA), GÉANT and RedCLARA’s BELLA project directly connecting Europe and Latin America, Japan’s SINET 100G project are enabling researchers across the globe to realize 100G connectivity.
Dr. Julio Ibarra presented current status or regional network infrastructure and planned activities for continuing the building of express backbone and enhancing the resilience of the AmLight ExP project for 2019. The achievement of those goals will facilitate effective peering among academic networks and communities of interest in response to the network requirements from research communities and can succeed through cooperation and collaboration.
