Outline • ESnet’s Role in DOE’s Office of Science • ESnet’s Continuing Evolutionary Dimensions • Capacity • Reach • Reliability • Guaranteed Services
DOE Office of Science and ESnet • “The Office of Science 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) • The large-scale science that is the mission of the Office of Science is dependent on networks for • Sharing of massive amounts of data • Supporting thousands of collaborators world-wide • Distributed data processing • Distributed simulation, visualization, and computational steering • Distributed data management • ESnet’s mission is to enable those aspects of science that depend on networking and on certain types of large-scale collaboration
The Office of Science U.S. Community 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 & Sandia National Laboratories Thomas Jefferson National Accelerator Facility General Atomics Oak Ridge National Laboratory Los Alamos National Laboratory Sandia National Laboratory National Renewable Energy Laboratory SC Program sites
Footprint of SC Collaborators - Top 100 Traffic Generators Universities and research institutes that are the top 100 ESnet users • The top 100 data flows generate 30% 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)
Changing Science Environment New Demands on Network • Increased capacity • Needed to accommodate a large and steadily increasing amount of data that must traverse the network • 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 • High network reliability • For interconnecting components of distributed large-scale science • New network services to provide bandwidth guarantees • For data transfer deadlines for remote data analysis, real-time interaction with instruments, coupled computational simulations, etc.
Network Utilization ESnet Accepted Traffic (Bytes)Jan 1990 to Jun 2006 ESnet is Currently Transporting over 1.2 Petabytes/monthand this volume is increasing exponentially 1.20 Petabyte/mo June 2006 1.04 Petabyte/mo April 2006 TBytes/Month
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
High Volume Science Traffic Continues to Grow • Top 100 flows are increasing as a percentage of total traffic volume • 99% to 100% of top 100 flows are science data (100% starting mid-2005) • A small number of large-scale science users account for a significant and growing fraction of total traffic volume 1/05 2 TB/month 6/05 2 TB/month 1/06 2 TB/month 7/06 2 TB/month
Who Generates ESnet Traffic? ESnet Inter-Sector Traffic Summary for June 2006 76% 7% Commercial DOE is a net supplier of data because DOE facilities are used by universities and commercial entities, as well as by DOE researchers 5% ESnet ~7% 30% R&E (mostlyuniversities) DOE sites 5% Peering Points 31% 31% International(almost entirelyR&E sites) DOE collaborator traffic, inc. data 14% 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 is Office of Science • less that 10% is inter-Lab

LIMAN and BNL • ATLAS (A Toroidal LHC ApparatuS), is one of four detectors located at the Large Hadron Collider (LHC) located at CERN • BNL is the largest of the ATLAS Tier 1 centers and the only one in the U.S, and so is responsible for archiving and processing approximately 20 percent of the ATLAS raw data • During a recent multi-week exercise, BNL was able to sustain an average transfer rate from CERN to their disk arrays of 191 MB/s (~1.5 Gb/s) compared to a target rate of 200 MB/s • This was in addition to “normal” BNL site traffic
CHIMAN: FNAL and ANL • Fermi National Laboratory is the only US Tier1 center for the Compact Muon Solenoid (CMS) experiment at LHC • Argonne National Laboratory will house a 5-teraflop IBM BlueGene computer part of the National Leadership Computing Facility • Together with ESnet, FNAL and ANL will build the Chicago MAN (CHIMAN) to accommodate the vast amounts of data these facilities will generate and receive • Five 10GE circuits will go into FNAL • Three 10GE circuits will go into ANL • Ring connectivity to StarLight and to the Chicago ESnet POP

Guaranteed Services Using Virtual Circuits • Traffic isolation and traffic engineering • Provides for high-performance, non-standard transport mechanisms that cannot co-exist with commodity TCP-based transport • Enables the engineering of explicit paths to meet specific requirements • e.g. bypass congested links, using lower bandwidth, lower latency paths • Guaranteed bandwidth [Quality of Service (QoS)] • Addresses deadline scheduling • Where fixed amounts of data have to reach sites on a fixed schedule, so that the processing does not fall far enough behind that it could never catch up – very important for experiment data analysis • Reduces cost of handling high bandwidth data flows • Highly capable routers are not necessary when every packet goes to the same place • Use lower cost (factor of 5x) switches to relatively route the packets • End-to-end connections are required between Labs and collaborator institutions
