| Lawrence Berkeley National Laboratory |
| Support the large-scale, collaborative science of DOE’s Office of Science | |
| Provide high reliability networking to support the operational traffic of the DOE Labs | |
| Provide network services to other DOE facilities | |
| Provide leading-edge network and Grid services to support collaboration | |
| ESnet is a component of the Office of Science infrastructure critical to the success of its research programs (program funded through Office of Advanced Scientific Computing Research / MICS; managed and operated by ESnet staff at LBNL) |
Drivers for the Evolution of ESnet
Evolving Quantitative Science Requirements for Networks
ESnet is Currently Transporting About 350 terabytes/mo.
A Small Number of Science
Users
Account for a Significant Fraction of all ESnet Traffic
Top Flows - ESnet Host-to-Host, 2 Mo., 30 Day Averaged
| Since BaBar (SLAC high energy physics experiment) production started, the top 100 ESnet flows have consistently accounted for 30% - 50% of ESnet’s monthly total traffic | ||
| As LHC (CERN high energy physics accelerator) data starts to move, this will increase a lot (200-2000 times) | ||
| Both LHC tier 1 (primary U.S. experiment data centers) are at DOE Labs – Fermilab and Brookhaven | ||
| U.S. tier 2 (experiment data analysis) centers will be at universities – when they start pulling data from the tier 1 centers the traffic distribution will change a lot | ||
Monitoring DOE Lab ↔ University Connectivity
| With the current architecture ESnet cannot address | |||
| the increasing reliability requirements | |||
| Labs and science experiments are insisting on network redundancy | |||
| the long-term bandwidth needs | |||
| LHC will need dedicated 10/20/30/40 Gb/s into and out of FNAL and BNL | |||
| Specific planning drivers include HEP, climate, SNS, ITER and SNAP, et al | |||
| The current core ring cannot handle the anticipated large science data flows at affordable cost | |||
| The current point-to-point tail circuits are neither reliable nor scalable to the required bandwidth | |||
ESnet Strategy – A New Architecture
| Goals derived from science needs | |||
| Fully redundant connectivity for every site | |||
| High-speed access to the core for every site (at least 20 Gb/s) | |||
| 100 Gbps national bandwidth by 2008 | |||
| Three part strategy | |||
| 1) Metropolitan Area Network (MAN) rings to provide dual site connectivity and much higher site-to-core bandwidth | |||
| 2) A Science Data Network core for | |||
| large, high-speed science data flows | |||
| multiply connecting MAN rings for protection against hub failure | |||
| a platform for provisioned, guaranteed bandwidth circuits | |||
| alternate path for production IP traffic | |||
| 3) A High-reliability IP core (e.g. the current ESnet core) to address Lab operational requirements | |||
New ESnet
Strategy:
Science Data Network + IP Core + MANs
Tactics for Meeting Science Requirements – 2007/2008
ESnet Services Supporting Science Collaboration
| In addition to the high-bandwidth network connectivity for DOE Labs, ESnet provides several other services critical for collaboration | ||||
| That is ESnet provides several “science services” – services that support the practice of science | ||||
| Access to collaborators (“peering”) | ||||
| Federated trust | ||||
| identity authentication | ||||
| PKI certificates | ||||
| crypto tokens | ||||
| Human collaboration – video, audio, and data conferencing | ||||
DOEGrids CA Usage - Virtual Organization Breakdown
ESnet Collaboration Services: Production Services
ESnet Collaboration Services: H.323 Video Conferencing
| Radvision and Codian | ||
| 70 ports on Radvision available at 384 kbps | ||
| 40 ports on Codian at 2 Mbps plus streaming | ||
| Usage leveled, but, expect increase in early 2005 (new groups joining ESnet Collaboration) | ||
| Radvision increase to 200 ports at 384 kbps by mid-2005 | ||
| ESnet is an infrastructure that is critical to DOE’s science mission and that serves all of DOE | |
| ESnet is working on providing the DOE mission science networking requirements with several new initiatives and a new architecture | |
| ESnet is very different today in both planning and business approach and in goals than in the past | |
