  1. ESnet4: Networking for the Future of DOE ScienceESnet R&D Roadmap Workshop, April 23-24, 2007 William E. Johnston ESnet Department Head and Senior ScientistLawrence Berkeley National Laboratory wej@es.net, www.es.net

  2. ESnet is an important, though somewhat specialized, part of the US Research and Education infrastructure • The Office of Science (SC) is the single largest supporter of basic research in the physical sciences in the United States, … providing more than 40 percent of total funding … for the Nation’s research programs in high-energy physics, nuclear physics, and fusion energy sciences. (http://www.science.doe.gov) • SC will supports 25,500 PhDs, PostDocs, and Graduate students, and half of the 21,500 users of SC facilities come from universities • Almost 90% of ESnet’s 1+Petabyte/month of traffic flows to and from the R&E community

  3. DOE Office of Science and ESnet – the ESnet Mission • ESnet’s primary mission is to enable the large-scale science that is the mission of the Office of Science (SC) and that depends on: • Sharing of massive amounts of data • Supporting thousands of collaborators world-wide • Distributed data processing • Distributed data management • Distributed simulation, visualization, and computational steering • Collaboration with the US and International Research and Education community • ESnet provides network and collaboration services to Office of Science laboratories and many other DOE programs in order to accomplish its mission

  4. What ESnet Is • A large-scale IP network built on a national circuit infrastructure with high-speed connections to all major US and international research and education (R&E) networks • An organization of 30 professionals structured for the service • An operating entity with an FY06 budget of $26.6M • A tier 1 ISP (direct peerings will all major networks) • The primary DOE network provider • Provides production Internet service to all of the major DOE Labs* and most other DOE sites • Based on DOE Lab populations, it is estimated that between 50,000 -100,000 users depend on ESnet for global Internet access • additionally, each year more than 18,000 non-DOE researchers from universities, other government agencies, and private industry use Office of Science facilities * PNNL supplements its ESnet service with commercial service

  5. Office of Science US CommunityDrives ESnet Design for Domestic Connectivity Institutions supported by SC Major User Facilities DOE Specific-Mission Laboratories DOE Program-Dedicated Laboratories DOE Multiprogram Laboratories Pacific Northwest National Laboratory Idaho National Laboratory Ames Laboratory Argonne National Laboratory Brookhaven National Laboratory Fermi National Accelerator Laboratory Lawrence Berkeley National Laboratory Stanford Linear Accelerator Center Princeton Plasma Physics Laboratory Lawrence Livermore National Laboratory Thomas Jefferson National Accelerator Facility General Atomics Oak Ridge National Laboratory Los Alamos National Laboratory Sandia National Laboratories National Renewable Energy Laboratory

  6. Footprint of Largest SC Data Sharing CollaboratorsDrives the International Footprint that ESnet Must Support • Top 100 data flows generate 50% of all ESnet traffic (ESnet handles about 3x109 flows/mo.) • 91 of the top 100 flows are from the Labs to other institutions (shown) (CY2005 data)

  7. What Does ESnet Provide? - 1 • An architecture tailored to accommodate DOE’s large-scale science • Move huge amounts of data between a small number of sites that are scattered all over the world • Comprehensive connectivity • High bandwidth access to DOE sites and DOE’s primary science collaborators: Research and Education institutions in the US, Europe, Asia Pacific, and elsewhere • Full access to the global Internet for DOE Labs • ESnet is a tier 1 ISP managing a full complement of Internet routes for global access • Highly reliable transit networking • Fundamental goal is to deliver every packet that is received to the “target” site

  8. What Does ESnet Provide? - 2 • A full suite of network services • IPv4 and IPv6 routing and address space management • IPv4 multicast (and soon IPv6 multicast) • Primary DNS services • Circuit services (layer 2 e.g. Ethernet VLANs), MPLS overlay networks (e.g. SecureNet when it was ATM based) • Scavenger service so that certain types of bulk traffic can use all available bandwidth, but will give priority to any other traffic when it shows up • Prototype guaranteed bandwidth and virtual circuit services

  9. What Does ESnet Provide? - 3 • New network services • Guaranteed bandwidth services • Via a combination of QoS, MPLS overlay, and layer 2 VLANs • Collaboration services and Grid middleware supporting collaborative science • Federated trust services / PKI Certification Authorities with science oriented policy • Audio-video-data teleconferencing • Highly reliable and secure operation • Extensive disaster recovery infrastructure • Comprehensive internal security • Cyberdefense for the WAN

  10. What Does ESnet Provide? - 4 • Comprehensive user support, including “owning” all trouble tickets involving ESnet users (including problems at the far end of an ESnet connection) until they are resolved – 24x7x365 coverage • ESnet’s mission is to enable the network based aspects of OSC science, and that includes troubleshooting network problems wherever they occur • A highly collaborative and interactive relationship with the DOE Labs and scientists for planning, configuration, and operation of the network • ESnet and its services evolve continuously in direct response to OSC science needs • Engineering services for special requirements

  13. ESnet is a Highly Reliable Infrastructure “5 nines” (>99.995%) “4 nines” (>99.95%) “3 nines” Note: These availability measures are only for ESnet infrastructure, they do not include site-related problems. Some sites, e.g. PNNL and LANL, provide circuits from the site to an ESnet hub, and therefore the ESnet-site demarc is at the ESnet hub (there is no ESnet equipment at the site. In this case, circuit outages between the ESnet equipment and the site are considered site issues and are not included in the ESnet availability metric. Dually connected sites

  14. ESnet is An Organization Structured for the Service Network operations and user support(24x7x365, end-to-end problem resolution Deployment and WAN maintenance Network engineering, routing and network services, WAN security Applied R&D for new network services(Circuit services and end-to-end monitoring) Science collaboration services (Public Key Infrastructure certification authorities,AV conferencing, email lists, Web services) Internal infrastructure, disaster recovery,security Management, accounting, compliance 30.7 FTE (full-time staff) total

  15. ESnet FY06 Budget is Approximately $26.6M Approximate Budget Categories Target carryover: $1.0M Special projects (Chicago and LI MANs): $1.2M SC R&D: $0.5M Carryover: $1M Management and compliance: $0.7M SC Special Projects: $1.2M Other DOE: $3.8M Collaboration services: $1.6 Internal infrastructure, security, disaster recovery: $3.4M Circuits & hubs: $12.7M SC operating:$20.1M Operations: $1.1M Engineering & research: $2.9M WAN equipment: $2.0M Total expenses: $26.6M Total funds: $26.6M

  16. Planning the Future Network - ESnet4 There are many stakeholders for ESnet • SC programs • Advanced Scientific Computing Research • Basic Energy Sciences • Biological and Environmental Research • Fusion Energy Sciences • High Energy Physics • Nuclear Physics • Office of Nuclear Energy • Major scientific facilities • At DOE sites: large experiments, supercomputer centers, etc. • Not at DOE sites: LHC, ITER • SC supported scientists not at the Labs (mostly at US R&E institutions) • Other collaborating institutions (mostly US, European, and AP R&E) • Other R&E networking organizations that support major collaborators • Mostly US, European, and Asia Pacific networks • Lab operations (e.g. conduct of business) and general population • Lab networking organizations These accountfor 85% of allESnet traffic

  17. Planning the Future Network - ESnet4 • Requirements of the ESnet stakeholders are primarily determined by 1) Data characteristics of instruments and facilities that will be connected to ESnet • What data will be generated by instruments coming on-line over the next 5-10 years? • How and where will it be analyzed and used? 2) Examining the future process of science • How will the processing of doing science change over 5-10 years? • How do these changes drive demand for new network services? 3) Studying the evolution of ESnet traffic patterns • What are the trends based on the use of the network in the past 2-5 years? • How must the network change to accommodate the future traffic patterns implied by the trends?

  18. (1) Requirements from Instruments and Facilities Advanced Scientific Computing Research National Energy Research Scientific Computing Center (NERSC) (LBNL)* National Leadership Computing Facility (NLCF) (ORNL)* Argonne Leadership Class Facility (ALCF) (ANL)* Basic Energy Sciences National Synchrotron Light Source (NSLS) (BNL) Stanford Synchrotron Radiation Laboratory (SSRL) (SLAC) Advanced Light Source (ALS) (LBNL)* Advanced Photon Source (APS) (ANL) Spallation Neutron Source (ORNL)* National Center for Electron Microscopy (NCEM) (LBNL)* Combustion Research Facility (CRF) (SNLL)* Biological and Environmental Research William R.

  19. The Largest Facility: Large Hadron Collider at CERN LHC CMS detector 15m X 15m X 22m,12,500 tons, $700M human (for scale)

  20. (2) Requirements from Examiningthe Future Process of Science • In a major workshop [1], and in subsequent updates [2], requirements were generated by asking the science community how their process of doing science will / must change over the next 5 and next 10 years in order to accomplish their scientific goals • Computer science and networking experts then assisted the science community in • analyzing the future environments • deriving middleware and networking requirements needed to enable these environments • These were complied as case studies that provide specific 5 & 10 year network requirements for bandwidth, footprint, and new services

  21. Science Networking Requirements Aggregation Summary

  22. Science Network Requirements Aggregation Summary Immediate Requirements and Drivers

  23. 3) These Trends are Seen in Observed Evolution of Historical ESnet Traffic Patterns top 100 sites to siteworkflows Terabytes / month • ESnet Monthly Accepted Traffic, January, 2000 – June, 2006 • ESnet is currently transporting more than1 petabyte (1000 terabytes) per month • More than 50% of the traffic is now generated by the top 100 sites — large-scale science dominates all ESnet traffic

  24. ESnet Traffic has Increased by10X Every 47 Months, on Average, Since 1990 Apr., 2006 1 PBy/mo. Nov., 2001 100 TBy/mo. 53 months Jul., 1998 10 TBy/mo. 40 months Oct., 1993 1 TBy/mo. 57 months Terabytes / month Aug., 1990 100 MBy/mo. 38 months Log Plot of ESnet Monthly Accepted Traffic, January, 1990 – June, 2006

  25. Requirements from Network Utilization Observation • In 4 years, we can expect a 10x increase in traffic over current levels without the addition of production LHC traffic • Nominal average load on busiest backbone links is ~1.5 Gbps today • In 4 years that figure will be ~15 Gbps based on current trends • Measurements of this type are science-agnostic • It doesn’t matter who the users are, the traffic load is increasing exponentially • Predictions based on this sort of forward projection tend to be conservative estimates of future requirements because they cannot predict new uses • Bandwidth trends drive requirement for a new network architecture • New architecture/approach must be scalable in a cost-effective way

  26. Large-Scale Flow Trends, June 2006Subtitle: “Onslaught of the LHC”) Traffic Volume of the Top 30 AS-AS Flows, June 2006(AS-AS = mostly Lab to R&E site, a few Lab to R&E network, a few “other”) Terabytes FNAL -> CERN traffic is comparable to BNL -> CERNbut on layer 2 flows that are not yet monitored for traffic – soon)

  27. Traffic Patterns are Changing Dramatically total traffic,TBy total traffic, TBy • While the total traffic is increasing exponentially • Peak flow – that is system-to-system – bandwidth is decreasing • The number of large flows is increasing 1/05 6/06 2 TB/month 2 TB/month 7/05 2 TB/month 1/06 2 TB/month

  28. The Onslaught of Grids Question: Why is peak flow bandwidth decreasing while total traffic is increasing? Answer: Most large data transfers are now done by parallel / Grid data movers • In June, 2006 72% of the hosts generating the top 1000 flows were involved in parallel data movers (Grid applications) • This is the most significant traffic pattern change in the history of ESnet • This has implications for the network architecture that favor path multiplicity and route diversity plateaus indicate the emergence of parallel transfer systems (a lot of systems transferring the same amount of data at the same time)

  29. What is the High-Level View of ESnet Traffic Patterns? ESnet Inter-Sector Traffic Summary, Mar. 2006 7% Commercial 48% 5% ESnet Inter-Labtraffic ~10% 12% R&E (mostlyuniversities) DOE sites 3% Peering Points 58% 23% International(almost entirelyR&E sites) 43% Traffic coming into ESnet = Green Traffic leaving ESnet = Blue Traffic between ESnet sites % = of total ingress or egress traffic • Traffic notes • more than 90% of all traffic Office of Science • less that 10% is inter-Lab

  30. Requirements from Traffic Flow Observations • Most of ESnet science traffic has a source or sink outside of ESnet • Drives requirement for high-bandwidth peering • Reliability and bandwidth requirements demand that peering be redundant • Multiple 10 Gbps peerings today, must be able to add more bandwidth flexibly and cost-effectively • Bandwidth and service guarantees must traverse R&E peerings • Collaboration with other R&E networks on a common framework is critical • Seamless fabric • Large-scale science is now the dominant user of the network • Satisfying the demands of large-scale science traffic into the future will require a purpose-built, scalable architecture • Traffic patterns are different than commodity Internet

  31. Changing Science Environment  New Demands on Network Requirements Summary • Increased capacity • Needed to accommodate a large and steadily increasing amount of data that must traverse the network • High network reliability • Essential when interconnecting components of distributed large-scale science • High-speed, highly reliable connectivity between Labs and US and international R&E institutions • To support the inherently collaborative, global nature of large-scale science • New network services to provide bandwidth guarantees • Provide for data transfer deadlines for • remote data analysis, real-time interaction with instruments, coupled computational simulations, etc.

  32. ESnet4 - The Response to the Requirements I) A new network architecture and implementation strategy • Rich and diverse network topology for flexible management and high reliability • Dual connectivity at every level for all large-scale science sources and sinks • A partnership with the US research and education community to build a shared, large-scale, R&E managed optical infrastructure • a scalable approach to adding bandwidth to the network • dynamic allocation and management of optical circuits II) Development and deployment of a virtual circuit service • Develop the service cooperatively with the networks that are intermediate between DOE Labs and major collaborators to ensure and-to-end interoperability

  33. Next Generation ESnet: I) Architecture and Configuration • Main architectural elements and the rationale for each element 1) A High-reliability IP core (e.g. the current ESnet core) to address • General science requirements • Lab operational requirements • Backup for the SDN core • Vehicle for science services • Full service IP routers 2) Metropolitan Area Network (MAN) rings to provide • Dual site connectivity for reliability • Much higher site-to-core bandwidth • Support for both production IP and circuit-based traffic • Multiply connecting the SDN and IP cores 2a) Loops off of the backbone rings to provide • For dual site connections where MANs are not practical 3) A Science Data Network (SDN) core for • Provisioned, guaranteed bandwidth circuits to support large, high-speed science data flows • Very high total bandwidth • Multiply connecting MAN rings for protection against hub failure • Alternate path for production IP traffic • Less expensive router/switches • Initial configuration targeted at LHC, which is also the first step to the general configuration that will address all SC requirements • Can meet other unknown bandwidth requirements by adding lambdas
