Ever want to know how big research data moves around the globe? ESnet plays a significant role in supporting the great scientific conversations, collaborations, and experiments underway, wherever and whenever they occur. We move Exabytes of data around the world creating a global laboratory that accelerates scientific discovery.
In order to meet these needs of scientists, we are constantly looking for opportunities to expand our capabilities with our next generation network ESnet6, intelligent edge analytics, advanced network testbeds, 5G wireless, quantum networking and more.
Created in 1986, the U.S. Department of Energy’s (DOE’s) Energy Sciences Network (ESnet) is a high-performance network built to support unclassified science research. ESnet connects more than 40 DOE research sites—including the entire National Laboratory system, supercomputing facilities and major scientific instruments—as well as hundreds of other science networks around the world and the Internet.
Step 9: Why just rent fiber? Pick up your own dark fiber network at a bargain price for future expansion. In the meantime, boost your bandwidth to 100G for everyone. (2012)
Step 10: Here’s a cool idea, come up with a new network design so that scientists moving REALLY BIG DATASETS can safely avoid institutional firewalls, call it the Science DMZ, and get research moving faster at universities around the country. (2012)
Step 12: 100G is fast, but it’s time to get ready for 400G. To pave the way, ESnet installs a production 400G network between facilities in Berkeley and Oakland, Calif., and even provides a 400G testbed so network engineers can get up to speed on the technology. (2015)
Step 13: Celebrate 30 years as a research and education network leader, but keep looking forward to the next level. (2016)
The Naval Research Laboratory (NRL), in collaboration with the DOE’s Energy Sciences Network (ESnet), the International Center for Advanced Internet Research (iCAIR) at Northwestern University, the Center for Data Intensive Science (CDIS) at the University of Chicago, the Open Cloud Consortium (OCC) and significant industry support, have conducted a 100 gigabits per second (100G) remote I/O demonstration at the SC14 supercomputing conference in New Orleans, LA.
The remote I/O demonstration illustrates a pipelined distributed processing framework and software defined networking (SDN) between distant operating locations. The demonstration shows the capability to dynamically deploy a production quality 4K Ultra-High Definition Television (UHDTV) video workflow across a nationally distributed set of storage and computing resources that is relevant to emerging Department of Defense data processing challenges.
As science transitions from lab-oriented to a distributed computational and data-intensive activity, the research and education (R&E) networking community is tracking the growing data needs of scientists. Huge instruments like the Large Hadron Collider are being planned and built. These projects require global-scale collaborations and contributions from thousands of scientists, and as the data deluge from the instruments grows, even more scientists are interested in analyzing it for the next breakthrough discovery. Suffice it to say that even though worldwide video consumption on the Internet is driving a similar increase in commercial bandwidth, the scale, characteristics, and requirements of scientific data traffic is quite different.
And this is why ESnet got invited to Cisco Systems’ headquarters last week to talk about how we how we handle data as part of their regular Nerd Lunch talk series. What I found interesting although not surprising, was that with Cisco being a big evangelist of telepresence, more employees attended the talk from their desks than in person. This was a first for me and I came away with a new appreciation for the challenges of collaborating across distances.
From a speaker’s perspective, the lesson learnt by me was to brush up my acting skills. My usual preparations are to rehearse the difficult transitions and focus on remembering the few important points to make on every slide. When presenting, that slide presentation portion of my brain goes on auto-pilot, while my focus turns towards evaluating the impact on the audience. When speaking at a podium one can observe when someone in the audience opens a notebook to jot down a thought, when their attention drifts to email on the laptop in front of them, or when a puzzled look appears on the face of someone as they try to figure out the impact of the point I’m trying to make. But these visual cues go missing with a largely webcast audience, making it harder to know when to stop driving home a point or when to explain the point further to the audience. In the future, I’ll have to be better at keeping the talk interesting without the usual clues from my audience.
Maybe the next innovation in virtual-reality telepresence is just waiting to happen?
Notwithstanding the challenges of presenting to a remote audience, enabling remote collaboration is extremely important to ESnet. Audio, video and web collaboration is a key service offered by us to the DOE labs. ESnet employees use video extensively in our day-to-day operations. The “ESnet watercooler”, a 24×7 open video bridge, is used internally by our distributed workforce to discuss technical issues, as well as, to have ad-hoc meetings on topics of interest. As science goes increasingly global, scientists are also using this important ESnet service for their collaborations.
With my brief stint in front of a stage now over, it is back to ESnet and then on to the 100G invited panel/talk at IEEE ANTS conference in Mumbai. Wishing all of you a very Happy New Year!
Last month was the first in which the ESnet network crossed a major threshold – over 10 petabytes of traffic! Traffic volume was 40% higher than the prior month and 10 times higher than just a little over 4 years ago. But what’s behind this dramatic increase in network utilization? Could it be the extreme loads ESnet circuits carried for SC10, we wondered?
Breaking down the ESnet traffic highlighted a few things. Turns out it wasn’t all that demonstration traffic sent across thousands of miles to the Supercomputing Conference in New Orleans (151.99 TB delivered), since that accounted for only slightly more than 1% of November’s ESnet-borne traffic. We observed for the first time significant volumes of genomics data traversing the network as the Joint Genome Institute sent over 1 petabyte of data to NERSC. JGI alone accounted for about 10% of last month’s traffic volume. And as we’ve seen since it went live in March, the Large Hadron Collider continues to churn out massive datasets as it increases its luminosity, which ESnet delivers to researchers across the US.
Summary of Total ESnet Traffic, Nov. 2010
Total Bytes Delivered: 10.748 PB
Total Bytes OSCARS Delivered: 5.870 PB
Pecentage of OSCARS Delivered: 54.72%
What is is really going on is quite prosaic, but to us, exciting. We can follow the progress of distributed scientific projects such as the LHC by tracking the proliferation of our network traffic, as the month-to-month traffic volume on ESnet correlates to the day-to-day conduct of science. Currently, Fermi and Brookhaven LHC data continue to dominate the volume of network traffic, but as we see, production and sharing of large data sets by the genomics community is picking up steam. What the stats are predicting: as science continues to become more data-intensive, the role of the network will become ever more important.
As SC10 wound down, ESnet started disassembling the network of connections that brought experimental data from the rest of the country to New Orleans, (and at least a bit of the universe as well). We detected harbingers of 100Gbps in all sorts of places. We will be sharing our observations on promising and significant networking technologies with you in blogs to come.
We were impressed by the brilliant young people we saw at the SC Student Cluster Competition organized collaboratively part of SC Communities, which brings together programs designed to support emerging leaders and groups that have traditionally been under-represented in computing. Teams came from U.S. universities, including Purdue, Florida A&M, SUNY Stonybrook, and University of Texas at Austin, as well as universities from China and Russia.
As SC10 concluded, the computer scientists and network engineers on the streets of the city dissipated, replaced by a conference of anthropologists. SC11 is scheduled for Seattle. But before we go, a note of appreciation to New Orleans.
Across from the convention center is a memorial to the people lost to Katrina; a sculpture of a wrecked house pinioned in a tree. But if you walk down the street to the corner of Bourbon and Canal, each night you will hear the trumpets of the ToBeContinued Brass Band. The band is a group of friends who met in their high school marching bands and played together for years until scattered by Katrina. Like the city, they are regrouping, and are profiled in a new documentary.
Our mission at ESnet is to help scientists to collaborate and share research. But a number of ESnet people are also musicians and music lovers, and we draw personal inspiration from the energy, technical virtuosity and creativity of artists as well as other engineers and scientists. We are not alone in this.
New Orleans is a great American city, and we wish it well.
During the SC10 conference, NASA, NOAA, ESnet, the Dutch Research Consortium, US LHCNet and CANARIE announced that they would transmit 100Gbps of scientific data between Chicago and New Orleans. Through the use of 14 10GigE interconnects, researchers attempted to completely utilize the full 100 Gbps worth of bandwidth by producing up to twelve 8.5-to-10Gbps individual data flows.
Brian Tierney reports: “We are very excited that a team from NASA Goddard completely filled the 100G connection from the show floor to Chicago. It is certainly the first time for the supercomputing conference that a single wavelength over the WAN achieved 100Gbps. The other thing that is so exciting about it that they used a single sending host to do it.”
“Was this just voodoo?” asked NERSC’s Brent Draney.
Tierney assures us that indeed it must have been… but whatever they did, it certainly works.
ESnet’s Jon Dugan will lead a Bof on network measurement 12:15, Thurs in room 278-279 at SC10. Functional networks are critical to high performance computing, but to achieve optimal performance, it is necessary to accurately measure networks. Jon will open up the session to discuss ideas in measurement tools such as perfSONAR, emerging standards, and the latest in research directions.
It is midafternoon Wednesday at SC10 and the demos are going strong. Jon Dugan supplied an automatically updating graph in psychedelic colors http://bit.ly/9HUrqL of the traffic ESnet is able to carry with all the circuits we set up. Getting this far required many hours of work from a lot of ESnet folk to accommodate the virtual circuit needs of both ESnet sites and SCinet customers using the OSCARS IDC software. As always, the SCinet team has put in long hours in a volatile environment to deliver a high performance network that meets the needs of the exhibitors.
At 1 p.m. at Berkeley Lab booth 2448, catch ESnet’s Inder Monga’s round-table discussion on OSCARS virtual circuits. OSCARS, the acronym for On- demand Secure Circuits and Advance Reservation System, allows users to reserve guaranteed bandwidth. Many of the demos at SC10 are being carried by OSCARS virtual circuits which were developed by ESnet with DOE support. Good things to come: ESnet anticipates the rollout of OSCARS 0.6 in early 2011. Version 0.6 will offer greatly expanded capabilities and versatility, such as a modular architecture enabling easy plug and play of the various functional modules and a flexible path computation engine (PCE) workflow architecture.
Then, stick around, because next at 2 p.m. Brian Tierney from ESnet will lead a roundtable on the research being produced from the ARRA-funded Advanced Networking Initiative (ANI) testbed.
In 2009, the DOE Office of Science awarded ESnet $62 million in recovery funds to establish ANI, a next generation 100Gbps network connecting DOE’s largest unclassified supercomputers, as well as a reconfigurable network testbed for researchers to test new networking concepts and protocols.
Brian will discuss progress on the 100Gbps network, update you on the several research projects already underway on the testbed, discuss testbed capabilities and how to get access to the testbed. He will also answer your questions on how to submit proposals for the next round of testbed network research.
In the meantime, some celeb-spotting at the LBNL booth at SC10.
