Russia-China-USA Science & Education Network


Why GLORIAD?• Time to develop follow-on to NaukaNet program

• Science applications demand it (HEP, ITER, NVO, Atmospheric Sciences, Spallation Neutron Source, Nanomaterials collaborations, network security, etc.)

• Desire to extend S&E network in Russia to Far East

• TransTelecom network in place

• Highest level interest in US for improving US-China S&E cooperation

• Highest level interest in Russia for improving Russia-China S&E cooperation

• Good opportunity to develop general framework for tri-lateral cooperation around a most advanced S&E network


Introduction to GLORIAD

• Proposed network/program to be operational in 2004

• Co-developed (and to-be-co-funded) by U.S., Russia, China

• Expanded capacity for science and education collaboration (10 Gbps)

• New “Global Ring” topology for reliability and new applications

• Essential for supporting advanced S&E applications (particularly HEP, Astronomy, Atmospheric Sciences, optical network research, network security research)

• Follow-on to US-Russian NaukaNet Program


Details (initial proposal)

• Layer 1: 10 Gbps Lambda ring across Russia, China, US (and the oceans between) (likely access point in Amsterdam also)

• Layer 2: Switched Ethernet• Layer 3: IPv6• Program to develop network management, utilization,

monitoring, resource allocation and scheduling tools• Program to develop Cyberinfrastructure supporting

S&E collaboration• Program to educate potential users and to

educate/inform continuously scientists/educators in all 3 countries about opportunities to collaborate


The 4 Layer GLORIAD Model


Collaboration Framework

Sculpted Network Platform

Lightwave/Lambda Network

Scientists, educators, policy-makers, public organizations, students

Middleware/grid tools, technologies tying together networks, computers and communities

Ethernet (layer 2) switching, IPv6 migration, Network monitoring and management (scheduling, allocation) tools

Lambda-based network; optical switching


Goal: Applications

• Network will carry the full mix of S&E traffic

• Emphasis, however, on supporting single applications that need Gbps+ capacity– ITER-Grid (US, China have just (re-) joined)

– HEP: LHC data distribution

– National Astronomy Virtual Observatory

– Climate change / atmospheric sciences

– Digital Sky

– Digital Earth

– Wavelength Disk Drive (based on Canadian efforts)

– Data mining, security monitoring and visualization

– Large scale digital video services


Serving Major Science/Education Application AreasGLORIAD is being developed to serve global S&E collaborations. The following

lists a few typical programs or program areas in which at least two (and in many cases, all three) of the countries jointly participate.

• USA: International Space Station Alpha • DOE Arms Control Policy Studies • National Nanotechnology Initiative • Human Genomics • Nuclear Threat Initiative (NTI) • Grid Physics Network • Cooperative Threat Reduction Program • MPC&A • Antarctic Research Programs • Earth Observation • The Globe Program

• Russia: ITER • Large Hadron Collider (LHC) • U.S.-Russia Joint Commission on Economic & Technological Cooperation • Seismic / Geological Research Programs • HERA-B (proton-electron accelerator) • Forest and Wildfire Research • Controlled Thermonuclear Fusion • Irkutsk Project • Junior Achievement • Simple Words Children’s Program • Neurosurgery International • Plasma Physics

• China:Yangtze River / Three Gorges • Space Telescope Program • Large Radio Telescope (FAST / KARST) • U.S.-China National Laboratory Interactions in Arms Control / Nonproliferation • China Biodiversity Network • U.S.-China Joint S&T Commission • Russia-China Oil Pipeline Project • Shanghai Cooperation Organization


Technical Details (initial proposal)

• Initial capability to switch multiple ethernet segments

• Later capability to switch multiple lambdas (year 3)

• Optical (initially, Ethernet) switches in Chicago (Starlight), Amsterdam (NetherLight), Moscow (RusLight), Novosibirsk (SiberLight), Beijing (ChinaLight), Hong Kong (HKLight)

• Self-healing ring topology (ex: if network outage across Atlantic, US traffic to Moscow transits Pacific/China/Siberia)

• IPv6 proposed for advanced applications, security, future of IP networking


A series of “Starlight” type facilities providing services for lambda-switching, ethernet-switching, IPv6 routing, IPv4 routing. Also, a testbed for advanced network research.


Russian Backbone Network (RBnet)


China CSTNet (800 research facilities/institutions)


US High Performance Network (Abilene, pictured here, is one of several US networks; others include DOE’s Esnet, NASA’s NREN, US Govt network, etc.)


Financing

• Proposed 5 year Project (2003-2008)• Backbone cooperatively managed by US, China, Russia partners• Project cooperatively funded by US, China, Russia. • US commitment anticipated at $2.5M annually• Proposal: each country funds transit across its territory.• US funds 1/2 circuit to Russia and 1/2 circuit to China.• Russia funds 1/2 circuit to US.• China funds 1/2 circuit to US.• Each country funds personnel, equipment, operations necessary

for full program operation (i.e., distributed 24/7 NOC, training/support, security services, grid development, etc.)


Organizational Details• Russian Federation: Kurchatov Institute (Dr. Velikhov), Russian Academy

of Science (Dr. Velikhov), Joint Supercomputing Center (RAS), Ministry of Industry, Science & Technology, Ministry of Communications, Ministry of Education, Ministry of Atomic Energy. (TransTelecom: likely network provider)

• People’s Republic of China: CSTnet/CNIC, Chinese Academy of Science. (Dr. Jiang)

• U.S.A.: University of Illinois National Center for Supercomputing Applications (lead university), National Computational Science Alliance, U.S. National Science Foundation, U.S. Department of Energy. (several telecomm companies being evaluated as possible network providers) Also, National Academy of Engineering, San Diego Supercomputing Center, Argonne National Laboratory, Oak Ridge National Laboratory, Sandia National Laboratory, International Center for Advanced Internet Research (ICAIR) at Northwestern University, others. (Challenge: must present a nation-wide consortium of U.S. S&E community to match interest/level of commitment in Russia and China)

Trip Results


The Memorandum of UnderstandingThe Chinese Academy of Sciences represented by the Computer Network Information Center (CNIC), the Russian Research Center “Kurchatov Institute” and the US National Center for Supercomputing Applications (NCSA) of the University of Illinois jointly propose a new strategic framework for advancing S&E cooperation among the three countries and across the myriad disciplines comprising current and future collaborative research. Linking their scientific communities with an advanced S&E network and Grid-based services, the multi-national GLORIAD program will actively encourage and coordinate applications across multiple disciplines and provide for sharing such scientific resources as databases, instrumentation, computational services, software, etc. In addition to supporting active scientific exchange with network services, the program will provide a test bed for advancing the state-of-the-art in collaborative and network technologies – including Grid-based applications, optical network switching, an IPv6 backbone, network traffic engineering and network security. Supporting the increasing growth in global S&E cooperation, GLORIAD will cooperate with other national S&E networks and scientific resources as required.


Lightwave/Lambda Network

• 10 Gbps Lambda Continuous Ring (segmented into multiple GigE ethernets)

• Need to decide carrier issues, meet points, etc.

• Russia’s network will be ready (to Russia-China border) in late 2003

• China’s network will be ready (to Russia-China border) in early 2004

• Important in later phase of project (year 3) that we have multiple lambdas (at least, when needed) and capability to switch lambdas on demand


Action Items

• Determine carrier issues for trans-Atlantic and trans-Pacific links. Must choose carrier with stable financial base, excess lambda capacity, eagerness to work on large R&D project.

• Finalize arrangements with Russian company TransTelecom

• Finalize transit issues within and to/from China

• Finalize network topology (optical nodes, facilities, equipment)


Resource Access/Scheduling System

• Provide for ability to advance-schedule resource allocation requests end-to-end

• Software system to automatically update network devices

• Must handle Level 2 switching for end-to-end VLAN provisioning

• Must handle Level 3 routing for providing improved QoS through core network (for example, using MPLS or other service)

• Must by year 3 provide for scheduling/switching (at optical level) lightwaves

• Must provide back-end reporting and surveying to determine how well network met customer’s needs


Collaboration Framework

• Middleware/grid tools, technologies (“Cyberinfrastructure”)– Collaboration

– Sharing of computational resources

– Sharing of storage/data resources

– Sharing of expensive/scarce instrumentation, sensor data, etc.


Global Grid Development

• GLORIAD will provide the network linking GRID communities in US, Russia and China (and, via Starlight and Netherlight, other countries)

• Will support the general US-Russian NaukaGrid program and other focused Grid communities


ITER-Grid Development

• Dr. Velikhov’s goal: “Virtual ITER” sites with ready, immediate access to conferencing facilities, live data streams generated by experiments/operations, distributed access to computational resources, remote instrumentation, monitoring and control applications.

• Need conferencing/lecture capabilities immediately (AG?)

• Network needs will eventually exceed 10 Gbps

• Preparing “concept paper” on what the ITER-Grid will be

• Would like to propose joint development effort: NCSA, Argonne, ORNL, others?


Kurchatov Institute Conferencing Facilities

• Currently based on several H.323 (polycom) devices

• Would like to add Access Grid node– Useful for KI collaborations

with NCSA, ORNL, Argonne, Sandia, ITER/fusion community

– Useful model for other Russian sites (implement multicast network across Russian S&E network)

– NaukaNet network capable

• GLORIAD is to focus on application communities - especially those with needs which could not be met without such an advanced network

• First, need to identify and document needs of these communities

• Second, need to educate/inform scientists, educators, students about potential services, capabilities

• Third, need to continually inform/update broad community about opportunities of collaboration


Active interest in GLORIAD program

• Signed Statement of the US-Russian Joint Committee for Science and Technology (J. Marburger, M.P. Kirpichnikov)

• Presentation to President’s Science Advisory Council, Russian Federation

• Signed Agreement (March 12, 2003) between 7 Russian Ministries, Russian Academy of Science & RRC Kurchatov Institute


Signed Statement of US-Russian S&T Commission

Informational and Telecommunication Technologies in Science and Education

The Committee gave a favorable appraisal of the results achieved through cooperation between the Russian Ministry of Industry, Science, and Technology (MIST) and the Russian Academy of Sciences (RAS) and the U.S. National Science Foundation (NSF) on high capacity computing and new generation computer networks, including under the NaukaNet (FASTnet) Project, carried out by the Interagency Supercomputer Center, the Russian Science Center Kurchatov Institute, the National Center for Supercomputing Applications (University of Illinois, Urbana-Champaign), and the Supercomputer Center at the University of California, San Diego.

The Committee recommended that U.S. and Russian cooperation partners continue their active cooperation and discussions of the potential of next-generation computing and networking projects, such as those envisioned as the "TERRA GRID" network and the Global Network For Advanced Application Development (GLORIAD).


Presentation to Russian S&T Council

January 2003: The forum was the President's Science & Technology Council and the participants included -- in addition to the President (who presides over this council) -- the nation's most senior science officials (including the Minister of Science, Industry & Technology, the President of the Russian Academy of Science and the President of the Kurchatov Institute (Dr. Velikhov)), and also the Finance Minister (and Vice Premier), the Minister of Commerce, the Minister of Atomic Energy and the head of the National Security Council.

“Where the Kurchatov Institute leads, Russia follows”

(Russian President)


Signed Russian Agreement

• On Wednesday, March 12, 2003, Dr. Velikhov placed the final signature on a document developed by 7 senior organizations in Russia indicating support and intention to pursue implementation of GLORIAD.

• It was signed at the Minister level by Ministry of Industry, Science & Technology, Ministry of Communications, Ministry of Atomic Energy and Ministry of Education. Also, the President of the Russian Academy of Sciences signed on behalf of the Academy and Dr. Velikhov on behalf of Kurchatov Institute (and as project organizer/lead).

• The agreement is to not only fund the international and networking parts of GLORIAD but also domestic infrastructure and programs to enable the science and education communities to utilize GLORIAD.

• Finally, we understand that Russian federal funds are now obligated for GLORIAD -- from the above organizations -- the Ministry of Industry, Science & Technology will be the financially responsible organization.


GLORIAD Proposal

• Ready in summer, 2003• Joint proposal preparation so that document is useful in

US, Russia and China• Primary focus on applications served by unique

network services as well as advanced network research development test bed

• Beginning to coordinate closely with other HPIIS teams: TransPAC (J. Williams), EuroLink (T. DeFanti), Starlight (T. DeFanti, J. Mambretti) (next meetings: May 2003)
