Internet2

We were pleased to see so many Internet2 members—and to make many new acquaintances—at the recent SC12 event in Salt Lake City. Whether you were able to stop by our booth or we missed each other this time, we hope your conference experience was a good one.

This year, some of the Internet2 community’s advanced science applications were featured on Salt Lake City's ABC 4 morning news live from the Internet2 booth on the show floor.   This and other stories highlighted Internet2’s  8.8 Tbps, 100G network and its support for members, like the National Oceanic and Atmospheric Administration (NOAA), which displayed Science on a Sphere – a visualization of weather satellite “big data” compiled by climate and atmospheric scientists. 

NOAA expert, Beth Russell demonstrated the visualization throughout SC12 in the Internet2 booth.

 

Internet2's Randy Brogle explained how the 100G Internet2 Network accelerates world-class science.

Other coverage included SC12 Vice Chair Wilford Pinfold discussing the importance of SC technologies in our daily lives.

Numerous Internet2 community members provided talks and demonstrations in the booth. Indiana University, Clemson University, the University of Utah, Brocade, Ciena, Juniper, the National Aeronautic and Space Administration (NASA) and NOAA offered compelling stories about their use of the Internet2 Network. In addition to the activities in the booth, Internet2 also supported member demonstrations across the show and made a significant contribution of technology and staff resources to SCinet.  

SCinet Research Sandbox
Jason Zurawski participated in the SCinet Research Sandbox entry, Exploiting Network Parallelism for Improving Data Transfer Performance:

Scientific applications can achieve significantly higher performance from virtually congestion-free dedicated resources provisioned on shared links, versus that of “opportunistic” network use. Research and Education (R&E) backbones, including the Energy Sciences Network and Internet2, provide general-purpose services to dynamically allocate bandwidth. However, in order to fully take advantage of this technology, application intelligence needs to move away from complex, coarse-grained, “reservation” strategies, to more sophisticated control functionalities based on software defined networking (SDN) with technologies such as OpenFlow.  This SCinet Research Sandbox (SRS) entry proposes, as one practical step toward nimble scientific data movement, using multiple paths for a single application transfer session. This has the additive effect of merging bandwidth from “best effort” and dedicated network paths, and can also facilitate performance with applications using multiple 10G NICs over 100G capable paths. This demonstration was a collaboration between ANL, LBNL, Indiana and Delaware.

SCinet-Internet2 link utilization
Internet2 provided high-speed wide area access links from SCinet to the Internet2 Network. To support the scientists at SC12, Internet2 deployed three 100 Gigabit Ethernet links to its new Software Defined Networking (SDN)-based Advanced Layer 2 Service, as well as two 10 GE links to its Research and Education IP backbone for a ginormous capacity of 320 Gigabits from a single provider. In addition, Internet2 staff Aaron Brown co-chaired the effort to measure and characterize all 772 Gigabits of capacity into SC12.

These graphs show the utilization of the IP link in real time. The utilization data is collected and displayed using the perfSONAR framework. Find out more at http://psps.perfsonar.net/.
