OSCARS 0.6 hits the limelight

At the recent Supercomputing11 conference, the bubbly was flowing. ESnet launched its ANI 100 gigabit-per-second network, and marked a quarter century of networking for DOE science. That big news may have overshadowed another milestone—SC11 was the first time OSCARS 0.6 was publicly demonstrated in a production environment. Now we’d like to give OSCARS its due.

OSCARS, or On-Demand Secure Circuits and Advance Reservation System, allows users to set up virtual circuits on demand to reserve bandwidth, streamlining the transfer of massive data sets across multiple network domains. OSCARS originated at ESnet, but we open-sourced it to the community long ago. Last spring the more modular OSCARS version 0.6 was released for testers and early adopters.

Other famous OSCARS

The performance of OSCARS 0.6 at SC11 showed us that we met our design goal of creating a flexible and modular framework. This was reflected in the demos, which were easy for folks to customize according to their needs. In the demo, “Enabling Large Scale Science using Inter-domain Circuits over OpenFlow” Tom Lehman of ISI used OSCARS to provide the functionality to control Openflow switches. Thanks to the flexibility to customize software built into OSCARS 0.6, ESnet’s Eric Pouyol was able to produce a variation of that application, customizing OSCARS 0.6 for resource brokering. OSCARS also played a part in the successful demonstration of Internet2’s Dynamic Network System (DYNES).The goal of DYNES is to work with regional networks and campuses, using OSCARS to schedule and support scientific data flows from the LHC, and other data intensive science programs such as LIGO, Virtual Observatory, and other large-scale sky surveys.

Most of the 100 Gbps demos at SC were supported by both the ANI 100 Gbps network and the 100 Gbps SCinet showfloor network. OSCARS 0.6 was used to schedule all eight of the demos using the 100 Gbps ANI network, which included complex visualizations of climate models, the Large Hadron Collider and the VERY early history—13.5 billion years ago, or 100 billion in dog years— of the Universe. OSCARS also controlled the approximately 100 different connections at SCInet, as well as connecting to three other OSCARS instances on the show floor.

OSCAR the Grouch

We used OSCARS 0.6 to provision the network, scheduling user time-slices of the 100 gigabit-per-second ANI and SCinet network, 24 hours a day, over the period of a week so they could test the demos in advance without having to get up at 3:00 a.m. to do it.

OSCARS 0.6 ended up making certain network engineers’ lives much easier. According to my colleague Evangelos Chaniatakis a.k.a. Vangelis, who was involved in the gritty details of setting up OSCARS 0.6 at the show, his team was required to make last-minute changes to the pre-existing network framework to work with the new hardware but didn’t receive the equipment until the week before the conference. The modularity ESnet built into OSCARS 0.6 helped the team get the network working at short notice.

 Less of a Software, More of a Service

Every year the number of reservations and circuits at SC continues to grow. The SC11 network required roughly twice the number of VLANs over the previous year. While the bandwidth wasn’t much bigger, and there were approximately the same number of customers, this year’s users definitely had more requirements. “On the whole OSCARS 0.6 was really stable.” Vangelis reports. “It worked fine.”  But the lessons learned at SC11 made us rethink the OSCARS 0.6 service module and requirements. In the near future, we intend to tweak OSCARS 0.6 to provide users more flexibility, making it less of a software and more of a service.

At 25, ESnet Transfers a Universe of Data

ESnet turns 25 this year. This anniversary marks a major inflection point in our evolution as a network in terms of bandwidth, capability, and control. We are running data through our network a billion—that is 10⁶—times faster than when ESnet was established.   Yet, we are still facing even greater demands for bandwidth as the amount of scientific data explodes and global collaborations expand.

Created in 1986 to meet the Department of Energy’s needs for moving research data and enabling scientists to access remote scientific facilities, ESnet combined two networks serving researchers in fusion research; (MFEnet) and high-energy physics (HEPnet). But ESnet’s roots actually stretch back to the mid-1970s, when staff at the CTR Computer Center at Lawrence Livermore National Laboratory installed four acoustic modems on a borrowed CDC 6600 computer. Our technology morphed over the years from fractional T1s to T1s to DS3, then to ATM, and in the last ten years we have moved to packet over SONET—all driven by the needs of our thousands of scientific users.

Over the last 25 years, ESnet has built an organization of excellence driven by the DOE science mission. We have consistently provided reliable service even as the science areas we support—high energy physics, climate studies, and cosmology, to name a few—have become exponentially more data-intensive. These fields especially rely on ever more powerful supercomputers to do data crunching and modeling. Other fields, such as genomics, are growing at a rapid pace as sequencing technologies become cheaper and more distributed.

Based on the dizzying trajectory of change in scientific computing technology, we urgently need to act now to expand the capacity of scientific networks in order to stay ahead of the demand in years to come.  At this point the ESnet high-speed network carries between 7 and 10 petabytes of data monthly (a single petabyte is equivalent to 13.3 years of HD video). The level of ESnet data traffic is increasing an average of 10 times every 4 years, steeply propelled by the rise in data produced. More powerful supercomputers can create more accurate models, for instance, of drought and rainfall patterns—but greater resolution requires vastly bigger datasets. Scientific collaborations can include thousands of researchers exchanging time-sensitive data around the world. Specialized facilities like the Large Hadron Collider and digital sky surveys produce torrents of data for global distribution. All these factors are poised to overload networks and slow scientific progress.

Tonight we face our biggest milestone yet: We are launching the first phase of our brand new 100 gigabit per second (Gbps) network, currently the fastest scientific network in the world today. Called the Advanced Networking Initiative (ANI), this prototype network forms the foundation of a soon-to-be permanent national network that will vastly expand our future data handling capacity.

The ANI prototype network will initially link researchers to DOE’s supercomputing centers: the National Energy Research Scientific Computing Center (NERSC) at Berkeley Lab, Oak Ridge Leadership Computing Facility (OLCF) , and Argonne Leadership Computing Facility (ALCF), as well as MANLAN, the Manhattan Landing Exchange Point.  ESnet will also deploy 100 Gbps-capable systems throughout the San Francisco Bay Area and Chicago. The ANI prototype network will then transition into a permanent, national 100 Gbps network, paving the way to an eventual terabit-scale DOE network.

To prepare the way, ESnet acquired almost 13,000 miles of dark fiber. This gives the DOE unprecedented control over the network and its assets, enabling upgrades and expansion to capacity and capabilities according to the needs of our scientists. By owning the fiber, we are able to lock in the cost of future upgrades for decades to come.

The third facet of ANI is a nationwide testbed which is being made available to researchers both in the public and private sector as a first of its kind platform to test experimental approaches to new network protocols and architectures in a greater than 10 Gbps network environment.

Researchers are already working on multiple experiments investigating emerging technologies like Remote Direct Memory Access (RDMA)-enabled data transfers at 40 Gigabits per second (Gbps) or new TCP congestion control algorithms that scale to 100Gbps and beyond. By creating a research testbed, ESnet will enable researchers to safely experiment with disruptive technologies that will build the next generation Internet—something impossible to do on networks that also carry daily production traffic.

Bringing You the Universe at 100 Gbps speed

Just this past week our engineers completed the installation of the first phase of network – nearly 6 weeks ahead of schedule. Tonight at the SC11 conference we are showcasing the inauguration of our brand new 100 Gbps network by demonstrating how high-capacity networks can open up the universe – or at least a highly sophisticated computer simulation of the early days of the universe.  The demo will include the transfer of over 5 terabytes of data over the new network from NERSC in Oakland, CA to the Washington State Convention Center in Seattle.

This demonstration is important as astrophysicists are interested in studying high-resolution simulations to better understand the complex structural patterns in the universe. ESnet’s new 100 Gbps network will enable scientists to interactively examine large datasets at full spatial and temporal fidelity without compromising data integrity. This novel capability will also enable remotely located scientists to gain insights from large data volumes located at DOE supercomputing facilities such as NERSC. For comparison purposes, a simulation utilizing a 10 Gpbs network connection will also be displayed on a complementary screen to showcase the vast difference in quality that a magnitude difference of bandwidth can bring to scientific discovery.

In addition to this great demo, seven other community collaborations will be leveraging the new ESnet 100 Gbps network to support innovative HPC demonstrations at SC11.

As we toast to this great new accomplishment this evening, we recognize that we are building on an amazing 25-year legacy in network innovation. We owe tremendous gratitude to the ESnet staff both past and present for their over two decades of hard work and dedication that has been keenly focused on helping the DOE community solve some of society’s greatest challenges.  Given our team’s accomplishments to date, I cannot wait to see what this next chapter in our history brings.

ECSEL leverages OpenFlow to demonstrate new network directions

ESnet and its collaborators successfully completed three days of demonstrating its End-to-End Circuit Service at Layer 2 (ECSEL) software at the Open Networking Summit held at Stanford a couple of weeks ago. Our goal is to build “zero-configuration circuits” to help science applications seamlessly use networks for optimized end-to-end data transport. ECSEL, developed in collaboration with NEC, Indiana University, and the University of Delaware builds on some exciting new conceptual thinking in networking.

Wrangling Big Data 

To put ECSEL in context, the proliferating tide of scientific data flows – anticipated at 2 petabytes per second as planned large-scale experiments get in motion – is already challenging networks to be exponentially more efficient. Wide area networks have vastly increased bandwidth and enable flexible, distributed, scientific workflows that involve connecting multiple scientific labs to a supercomputing site, a university campus, or even a cloud data center.

Heavy network traffic to come

The increasing adoption of distributed, service-oriented computing means that resource and vendor independence for service delivery is a key priority for users. Users expect seamless end-to-end performance and want the ability to send data flows on demand, no matter how many domains and service providers are involved.  The hitch is that even though the Wide Area Network (WAN) can have turbocharged bandwidth, at these exponentially increasing rates of network traffic even a small blockage in the network can seriously impair the flow of data, trapping users in a situation resembling commute conditions on sluggish California freeways. These scientific data transport challenges that we and other R&E networks face are just a taste of what the commercial world will encounter with the increasing popularity of cloud computing and service-driven cloud storage.

Abstracting a solution

One of the key feedback from application developers, scientists and end-users is that they do not want to deal with the complexity at the infrastructure level while still accomplishing their mission. At ESnet, we are exploring various ways to make networks work better for users. A couple of concepts could be game-changers, according to Open Network Summit conference presenter and Berkeley professor Scott Shenker: 1) using abstraction to manage network complexity, and 2) extracting and exposing simplicity out of the network. Shenker himself cites Barbara Liskov’s Turing Lecture as inspiration.

ECSEL is leveraging OSCARS and OpenFlow within the Software Defined Networking (SDN) paradigm to elegantly prevent end-to-end network traffic jams.  OpenFlow is an open standard to allow application-driven manipulation of network flows. ECSEL is using OSCARS-controlled MPLS virtual circuits with OpenFlow to dynamically stitch together a seamless data plane delivering services over multi-domain constructs.  ECSEL also provides an additional level of simplicity to the application, as it can discover host-network interconnection points as necessary, removing the requirement of applications being “statically configured” with their network end-point connections. It also enables stitching of the paths end-to-end, while allowing each administrative entity to set and enforce its own policies. ECSEL can be easily enhanced to enable users to verify end-to-end performance, and dynamically select application-specific protocol forwarding rules in each domain.

The OpenFlow capabilities, whether it be in an enterprise/campus or within the data center, were demonstrated with the help of NEC’s ProgrammableFlow Switch (PFS) and ProgrammableFlow Controller (PFC). We leveraged a special interface developed by them to program a virtual path from ingress to egress of the OpenFlow domain. ECSEL accessed this special interface programmatically when executing the end-to-end path stitching workflow.

Our anticipated next step is to develop ECSEL as an end-to-end service by making it an integral part of a scientific workflow. The ECSEL software will essentially act as an abstraction layer, where the host (or virtual machine) doesn’t need to know how it is connected to the network–the software layer does all the work for it, mapping out the optimum topologies to direct data flow and make the magic happen. To implement this, ECSEL is leveraging the modular architecture and code of the new release of OSCARS 0.6.  Developing this demonstration yielded sufficient proof that well-architected and modular software with simple APIs, like OSCARS 0.6, can speed up the development of new network services, which in turn validates the value-proposition of SDN. But we are not the only ones who think that ECSEL virtual circuits show promise as a platform for spurring further innovation. Vendors such as Brocade and Juniper, as well as other network providers attending the demo were enthusiastic about the potential of ECSEL.

But we are just getting started. We will reprise the ECSEL demo at SC11 in Seattle, this time with a GridFTP application using Remote Direct Memory Access (RDMA) which has been modified to include the XSP (eXtensible Session Protocol) that acts as a signaling mechanism enabling the application to become “network aware.”  XSP, conceived and developed by Martin Swany and Ezra Kissel of Indiana University and University of Delaware,  can directly interact with advanced network services like OSCARS – making the creation of virtual circuits transparent to the end user. In addition, once the application is network aware, it can then make more efficient use of scalable transport mechanisms like RDMA for very large data transfers over high capacity connections.

We look forward to seeing you there and exchanging ideas. Until Seattle, any questions or proposals on working together on this or other solutions to the “Big Data Problem,” don’t hesitate to contact me.

Routers, the Portal, and Transcontinental 100G Links – Oh My!

Things are moving quickly at ESnet, and we’re not talking only about data transfers.  Our Advanced Networking Initiative (ANI) 100G roll-out is gaining even more momentum and we are really gearing up for the SC11 conference next month.

This week, it was announced that we are working with LGS Innovations to deploy Alcatel-Lucent 7750 Service Routers (SR) on the new ANI prototype network. The first routers were delivered about a month ago and we are already well into acceptance testing and deployment. So far we have routers up and running in Sunnyvale, NERSC, StarLight and Argonne.  After we installed this equipment, our engineering team worked with Internet2 to light the first coast-to-coast network path from Washington, D.C. all the way to Sunnyvale in our backyard  –  the first 100G transcontinental link in the world! We were particularly proud of this milestone, which we reached well ahead of schedule. As next steps, we anticipate that 6 routers of our 10 total will be deployed in time for SC11.

To help the community keep tabs on our rapid ANI deployment progress, the ESnet Tools team has been expanding the MyESnet portal to provide a real-time view of the rollout. You can see the result of their efforts here.

This summer we introduced MyESnet to provide DOE Office of Science researchers and IT staff with a wide range of customized tools intended to greatly improve their ability to understand network issues in real time. The initial functionality includes a dashboard that provides a bird’s-eye view of the local area networks of the DOE facilities connected by ESnet, including their traffic patterns and system status.

Using this new ANI visualization tool, users can see which 100G network links are active, as well as information on each of our node and interconnect locations across the country.  The tool will be expanded to show traffic load in the near future.  In the next few weeks, the portal will also provide a real-time view of the eight community-driven projects that will use the new 100G network for large scale demonstrations at SC11. This interface will allow viewers to view the details and traffic load of these demonstrations.

With fewer than 25 days to go until SC11, our team is gearing up for some exciting announcements and ANI demos . . . check back for info on these activities soon and check in with us in Seattle. ESnet is part of Berkeley Lab booth 512.

Nobel Prize Lesson: Distinguish the Improbable from the Impossible

Saul Perlmutter was woken at 3 am yesterday by a reporter asking how he felt about winning the Nobel Prize. Any confusion was cleared up a few minutes later when the Nobel Committee in Sweden called. Perlmutter, an astrophysicist who holds a joint appointment at Berkeley Lab and UC Berkeley, and his colleagues Brian Schmidt and Adam Reiss received the 2011 Nobel Prize in Physics for their work in the 1990s in using supernovae to measure the accelerating expansion of the universe. They found, independently, improbable evidence that the universe was expanding at ever faster speeds.

In the process they uncovered other mysteries. The universe is made up of only about 5 percent visible (or baryonic) matter. The remaining 25 percent of the universe is dark matter, and 75 percent of the universe is made up of dark energy. Perlmutter described dark energy as making space more bouncy and elastic. It appears as “a negative pressure—we see it in the equations.” Nobody is certain of the relationship between dark matter and dark energy; scientists are looking for a theoretical concept that will solve them both at the same time.

In yesterday’s press conference at Berkeley Lab, Perlmutter said that the award “recognizes what it is possible to do when whole communities of science come together.” He went on to say, “when you are driven to learn things about the world, you find yourself inventing new things.”

Of course, that is what ESnet is all about—the ESnet network links scientists so they can efficiently exchange data, collaborate, and discover new things about the world. ESnet’s Bill Johnston recalls the early days of data transfer. “Saul started out doing observations at Chabot and Hamilton. He wrote the images on Tektronix cartridge tape and ferried them around in his car.  When his tape reader at LBL broke, we would help him out. In the graphics lab that Harvard Holmes and I ran, we had several Tek tape readers. That must have been [the] late 1970s.”

And then there’s Daniel Schectman, a hard-core materials scientist at the Technion-Israel’s Institute of Technology, who today was awarded the Nobel Prize in Chemistry for discovering a new state of matter called quasi-crystals, where atoms make a structured pattern that never repeats.  While on sabbatical at NIST in 1982, Schectman was working at the electron microscope, imaging a sample of aluminum and maganese. He made a measurement that seemed to be a mistake– the symmetry of its five-fold crystal structure violated the laws of physics. It is possible to get an identical pattern from structures with 3,4,6 and 8 sides, just like square floor tiles can be repeated in an identical pattern, no matter how you rotate them. But Schectman knew it was theoretically impossible to tile a space in five-fold rotational symmetry.

A former student who took his class in electron beam crystallography at the Technion recalls that Schectman showed the class the research notebook that he kept at NIST. Beside the measurement of the anomalous sample, Schectman scribbled in Hebrew, “there is no creature like that.” Schectman persisted through years of caustic opposition from his peers (Linus Pauling, a two time Nobel-winner, was particularly hostile), to verify his results—he was even asked to leave his research group. The original paper he attempted to publish in the Journal of Applied Physics in 1984 was immediately rejected, but he later published another paper with collaborators that rocked the field of crystallography.

It turns out that to tile a space and achieve five-fold symmetry uses not a single tile, but two—one distorted, a concept called Penrose tiling. But at the time, Schectman was unfamiliar with Roger Penrose’s work; it was an idea that only pure mathematicians played with–it wasn’t even applied mathematics. On an atomic level, quasi-crystals resemble aperiodic mosaics, such as those found in the medieval Islamic mosaics of the Alhambra Palace in Spain and the Darb-i Imam Shrine in Iran.

Schectman’s discovery caused a paradigm shift in chemistry, the Swedish Academy of Sciences said. But exotic quasi-crystals, since they don’t scratch easily, are now appearing in our everyday lives in the non-stick coatings on razor blades, drill-bits, and pots and pans.

Schectman and Perlmutter both stood on the shoulders of people who came before them, and relied on their communities to test and verify their results.  The pace of scope of modern day science is making international collaboration not a luxury, but a necessity. Although individual persistence and courage drive many new discoveries, they still take place in the context of a global community of scientists.  ESnet and other research and education networks make this community possible, by allowing scientists to share datasets and knowledge and to work together towards even greater discoveries.

“Science is a method, not a finished project; we don’t know where it will lead in the future,” Perlmutter summed up. And networks are forging the way.

Idea Power: Two ESnet Projects are Honored With Internet2 IDEA Awards

We are proud to announce that two of ESnet’s projects have received IDEA (Internet2 Driving Exemplary Applications) awards in Internet2’s 2011 annual competition for innovative network applications that have had the most positive impact and potential for adoption within the research and education community. (see: Internet2’s press release).

Internet2 recognized OSCARS (On-Demand Secure Circuits and Advance Reservation System), developed by the ESnet team led by Chin Guok, including Evangelos Chaniotakis, Andrew Lake, Eric Pouyoul and Mary Thompson. Contributing partners also included Internet2, USC ISI and DANTE.

ESnet’s MAVEN (Monitoring and Visualization of Energy consumed by Networks) proof of concept application was also recognized with an IDEA award in the student category. MAVEN was prototyped by Baris Aksanli during his summer internship at ESnet. Baris is a Ph.D student at the University of California, San Diego conducting research at the System Energy Efficiency Lab with his thesis advisor, Dr. Tajana Rosing. Baris worked closely with his summer advisor, Inder Monga, and Jon Dugan to implement MAVEN as part of ESnet’s new Green Networking Initiative.

The idea behind OSCARS

OSCARS enables researchers to automatically schedule and guarantee end-to-end delivery of scientific data across networks and continents. For scientists, being able to count on reliable data delivery is critical as scientific collaborations become more expansive, often global. Meanwhile, in disciplines ranging from high-energy physics to climate, scientists are using powerful, geographically dispersed instruments like the Large Hadron Collider that are producing increasingly massive bursts of data, challenging the capabilities of traditional IP networks.

OSCARS virtual circuits can reliably schedule time-sensitive data flows – like those from the LHC – round the clock across networks, enabling research and education networks to seamlessly meet user needs. OSCARS code is also being deployed by R&E networks worldwide to support an ever-growing user base of researchers with data-intensive collaboration needs. Internet2, U.S. LHCnet, NORDUNet, RNP in Brazil as well as over 10 other regional and national networks have currently implemented OSCARS for virtual circuit services. Moreover, Internet2’s NSF-funded DyGIR and DYNES projects will in 2012 deploy over 60 more instances of OSCARS at university campuses and regional networks to support scientists involved in LHC, Laser Interferometer Gravitational-Wave Observatory (LIGO), Large Synoptic Survey Telescope (LSST) and Electronic Very-Long Baseline Interferometry (eVLBI) programs.

We are proud of the hard work and dedication the OSCARS development team has demonstrated since the start of this project. Just as importantly we are proud to see this work paying off in with new science collaboration and discoveries.

The potential of MAVEN

The Monitoring and Visualization of Energy consumed by Networks (MAVEN) project is a brand new prototype portal that will help network operators and researchers better track live network energy consumption and environmental conditions. MAVEN – implemented by Baris during his summer internship – is a first major step for ESnet in instrumenting our network with the tools to understand these operational dynamics. As networks continue to get bigger and faster, they will require more power and cooling in an era of decreased energy resources. To address this pressing challenge, ESnet is leading a new generation of research aimed at understanding how networks can operate in a more energy-efficient manner. We are grateful for Baris’ significant contributions in leading the development of MAVEN and glad to see that his talent is being recognized by the R&E networking community through this award.

Baris is now back in school at UCSD, completing his Ph.D in computer science. http://cseweb.ucsd.edu/~baksanli/. Congratulations Baris!
