  5. Next-Generation Networks for Science Mission: The Goals of the program are 1) to research, develop, test and deploy advanced network technologies critical in addressing networking capabilities unique to DOE’s science mission and 2) identify scientific principles that lead to understanding about network and application behavior.  The program’s portfolio consists of two main elements: High-Performance Networks High-Performance Middleware DOE ESnet

  6. Data Transfer Basics • Time to transfer 1 TB on various networks • 1 TB/hour uses ¼ of a 10 Gbps network • 10 TB/hour uses ¼ of a 100 Gbps network • 100 TB/hour uses ¼ of a 1 Tbps network • Conversely a 1 Tbps network will move 10 PB/day • Real-time aspects at 100 Gbps • Voice (128B): 20.5 nsec/packet • Jumbo frame Ethernet (9KB): 720 nsec/packet

  7. CEDPS - SaaS Data Management Moving 322 TeraBytes of data from ANL to each remote site 7.34 Days to NERSC 18.56 Days to ORNL 4.1 Gbps 1.6 Gbps
