ESnet staff help mentor WINS participants at SC15

In addition to being connected to the world at 1.6 terabits per second, the recent SC15 conference in Austin provided powerful networking opportunities for five up-and-coming women network experts through the NSF-supported Women in IT Networking at SC (WINS) program. The program is aimed at training and mentoring women faculty and staff from institutions across the country by having them participate in SCinet, the ultra-high bandwidth network created each year to support SC.

Jason Zurawski, a member of ESnet’s Science Engagement Team and longtime SCinet member, mentored  WINS participants Sana Bellamine from CENIC and Megan Sorensen from Idaho State University.  Nick Boraglio of ESnet’s Network Engineering Team worked with Debbie Fligor from the University of Illinois Urbana-Champaign as members of the SCinet Routing Team.

Find Out What’s New, What’s Cool at ESnet at SC15

ESnet staff will be presenting talks and demos at the SC15 conference being held Nov. 15-20 in Austin. Here’s a quick look at some of your opportunities to find out what’s new with the Energy Sciences Network:

Tuesday, Nov. 17
ESnet Chief Technologist Inder Monga will hold a demo on “ESnet’s Network Operating System: An SDN Platform to Handle Big Science” from 10-11 a.m. in the DOE booth 502.

Jon Dugan of the Tools Team will host a demo on ESnet’s Network Visualization Tools from 11 a.m. to 12 p.m., followed by a roundtable discussion. Both will be in the DOE booth #502.

Wednesday, Nov. 18
ESnet Chief Technologist Inder Monga hosts a mini-panel presenting “The Future of DOE Networking: A Tasting Menu” served up at 1:45 p.m. in the DOE booth #502.

Monga will give a demo on “ESnet’s Network Operating System: An SDN Platform to Handle Big Science” from 4-5 p.m. in the DOE booth 502.

ESnet’s Inder Monga and Eric Pouyoul will demonstrate “Software-Defined Networking” in the Corsa Technology booth# 364. Corsa and ESnet will be demonstrating ENOS (ESnet Network Operating System) running on the 100G SDN ESnet Testbed. ENOS includes all components that are needed for automating complex network provisioning and optimization and it will control the Corsa SDN switch in real-time. The demo will be offered from 7 – 9 p.m. Monday, Nov. 16, 10:30 a.m. – 12 p.m. and 4:30-5:30 p.m. Tuesday and Wednesday, Nov. 17 – 18, and 10:30 a.m. – 12 p.m. Thursday, Nov. 19.

Attending SC15? Get a Close-up Look at Virtualized Science DMZs as a Service

ESnet, NERSC and RENCI are pooling their expertise to demonstrate “Virtualized Science SMZs as a Service”  at the SC15 conference being held Nov. 15-20 in Austin. They will be giving the demos at 2:30-3:30 p.m. Tuesday and Wednesday and 1:30-2:30 p.m. Thursday in the RENCI booth #181.

Here’s the background: Many campuses are installing ScienceDMZs to support efficient large-scale scientific data transfers. There’s a need to create custom configurations of ScienceDMZs for different groups on campus. Network function virtualization (NFV) combined with compute and storage virtualization enables a multi-tenant approach to deploying virtual ScienceDMZs. It makes it possible for campus IT or NREN organizations to quickly deploy well-tuned ScienceDMZ instances targeted at a particular collaboration or project. This demo shows a prototype implementation of ScienceDMZ-as-a-Service using ExoGENI racks (ExoGENI is part of NSF GENI federation of testbeds) deployed at StarLight facility in Chicago and at NERSC.

The virtual ScienceDMZs deployed on-demand in these racks use the SPOT software suite developed at Lawrence Berkeley National Laboratory to connect to a data source at Argonne National Lab and a compute cluster at NERSC to provide seamless end-to-end high-speed data transfers of data acquired from Argonne’s Advanced Photon Source (APS) to be processed at NERSC. The ExoGENI racks dynamically instantiate necessary compute virtual resources for ScienceDMZ functions and connect to each other on-demand using ESnet’s OSCARS and Internet2’s AL2S system.

ESnet’s Nick Buraglio Leading SCinet’s First SDN Effort at SC15

For the first time, SCinet, the research and production network for the SC conference series, will be using software defined networking (SDN) to manage and simplify the operations for a portion of the SC15 conference’s show floor network.  Nick Buraglio of the ESnet Network Engineering Group is leading the project.

SCinet is the research and production network that serves as the data communications backbone for the annual SC conference. By using SDN, the network engineers deploying SCinet will be able to transfer the task of configuring individual network switching devices to a single piece of software, removing human error from the process of setting up connections within the network.

“Take the last three problems or errors that have occurred on a network of any notable size,” says  Buraglio, “and it’s almost always a configuration problem—some kind of human error that caused those issues.” Deploying SDN will simplify managing these network connections and will hopefully reduce the time engineers spend troubleshooting configuration and provisioning errors.
