9 University of Illinois at Chicago Euro-Link Statement of Work #1: Connections To create and maintain a high-performance connection between the vBNS and European NRNs via STAR TAP –Provide high-performance circuits connecting European NRNs to NGI networks via STAR TAP –Implement and manage a Level 3 service –Provide a coordinated NOC, NIC and user services on a 24 x 7 basis

10 University of Illinois at Chicago Euro-Link Statement of Work Connections: CERN Star Tap 155Mb /s

11 University of Illinois at Chicago Euro-Link Statement of Work Connections: Israel

12 University of Illinois at Chicago Euro-Link Statement of Work Connections: Nordic Countries 155Mb

13 University of Illinois at Chicago Euro-Link Statement of Work Connections: France

14 University of Illinois at Chicago Euro-Link Statement of Work Connections: The Netherlands 622Mb SURFnet

15 University of Illinois at Chicago Euro-Link Statement of Work Connections: Level 2 and Level 3 Once connected to STAR TAP, the NRNs, in addition to connecting to the vBNS, can peer with other US NGI networks, the Internet2, and advanced networks from other countries. NRNs can peer using the STAR TAP Router or by bilateral agreement. They may also connect to one or more ISPs at the AADS facility, which is outside the scope of Euro-Link, but a useful capability nonetheless.

17 University of Illinois at Chicago Euro-Link NOC http://noc.euro-link.org HPIIS (Euro-Link, TransPAC, MIRnet) helps support the Global Research NOC staff, network engineers and applications engineers Jim Williams will present the Global NOC.

18 University of Illinois at Chicago Euro-Link Statement of Work #2: Ensuring High Performance Traffic To ensure, to the extent supportable by prudent application of networking technology, that only approved institutions traffic uses the high-performance connection –Implement routing and switching configurations consistent with AUPs of European NRNs and vBNS –Update routing and switching hardware and software as new capabilities for implementing routing policies become available –Document AUP traffic segregation measures and procedures on Euro-Link web site

19 University of Illinois at Chicago Euro-Link Statement of Work Ensuring High Performance Traffic Compliance with NSF vBNS AUP documented in Euro-Link annual report at http://www.euro-link.org/PUBLICATIONS/ Most of the NRNs have a policy to connect all the universities in their countries without discrimination as to research need; however, to comply with the NSF AUP, they segregate traffic either at home or on the US East Coast prior to connecting to STAR TAP

20 University of Illinois at Chicago Euro-Link Statement of Work #3: Monitoring Performance and Use To monitor Euro-Link performance and use –Monitor traffic parameters to manage the utilization of Euro-Link networks and assure high-performance quality –Develop a new generation of performance and analysis tools. Adopt and adapt emerging network performance monitoring technologies and develop advanced visualization, persistent databases and visualization/VR techniques to create new applications-oriented performance measuring tools for HPIIS

21 University of Illinois at Chicago Euro-Link Statement of Work Monitoring Performance and Use CERN provides its own Internet traffic statistics: http://sunstats.cern.ch/mrtg Performance monitoring – CERN hosts three Internet probes (Surveyor, RIPE and NIMI) and is also part of the Internet End- to-end Performance Monitoring (IEPM) PINGER project, supported by DOE MICS through the Stanford Linear Accelerator Center CERN has plans to install Netlogger and to study alternatives to TCP-based file transfer in order to reduce problems linked to error recovery on high-bandwidth delay paths

22 University of Illinois at Chicago Euro-Link Statement of Work Monitoring Performance and Use IUCC statistical information about all its connections (Home page): http://www.internet-2.org.il/stats.html IUCC FastEthernet1/0 traffic analysis: http://noc.ilan.net.il/stats/TAU- GIGAPOP/tau-gp1-fe-i2.ilan.net.il.html STAR TAP IUCC peering statistics: http://noc.ilan.net.il/stats/ILAN-I2- uplinks/peers.html IUCC has, in addition, installed an NLANR passive monitor: http://moat.nlanr.net/Datacube/Data/TAU/

23 University of Illinois at Chicago Euro-Link Statement of Work Monitoring Performance and Use NORDUnet NOC operations are carried out at KTH in Stockholm and by the national Nordic networks NORDUnet participates in the ANS Surveyor measurement infrastructure with UNINETT, operating a measurement station at the University of Oslo

24 University of Illinois at Chicago Euro-Link Statement of Work Monitoring Performance and Use RENATER2 does not presently have a web page regarding STAR TAP traffic. Hopefully this will change at some time this year, once the current call for tenders is completed. A higher transatlantic link, along with associated services, will improve performance.

25 University of Illinois at Chicago Euro-Link Statement of Work Monitoring Performance and Use STAR TAP SURFnet traffic monitoring: http://www.surfnet.nl/surfnet/persons/ bos/startap-traffic/ SURFnet monitors traffic on its STAR TAP connection, as it does on all its connections (external connections, backbone links, and customer links). Results are put on the web using MRTG or RRDTool. This information is typically protected by userid/passwds and access-lists

26 University of Illinois at Chicago Euro-Link Statement of Work Monitoring Performance and Use EVL visualization network performance analysis tools: Motivation QoSIMoTo (QoS Internet Monitoring Tool) visualizes historic as well as real-time Netlogger data consisting of bandwidth, latency and jitter: www.evl.uic.edu/cavern/qosimoto Forward Error Correction schemes, both parity- based and XOR-based, are being developed as an alternative to TCP for transmitting real-time data, which has substantial latency over international links. Jason Leigh will discuss this research this afternoon

27 University of Illinois at Chicago Euro-Link Statement of Work #4: Engineering Advancements Cooperate with vBNS and NLANR to develop testbeds of new networking protocols (IPv6, multicast and Mbone, resource reservation, cache services, etc.)

28 University of Illinois at Chicago Euro-Link Statement of Work Engineering Advancements CERN participates in the Internet2 Distributed Storage Initiative IPv6 (with Lawrence Berkeley Lab via 6TAP) Exploring DiffServ to deliver the required grade of service to its users (with iCAIR and EVL using STAR TAP DiffServ Router) –Working with Brian Carpenter, IBM/iCAIR, on the Virtual Room Video-conferencing System (VRVS) DiffServ testbed http://vrvs.cern.ch/About/VRVS_Paper.pdf High-speed file transfer with Caltech/SLAC/Fermilab

29 University of Illinois at Chicago Euro-Link Statement of Work Engineering Advancements IUCC is benchmarking and testing solutions that can negate the influence of large satellite delays that influence TCP throughput; results of testing two products at the Intelsat lab in Washington DC: www.internet-2.org.il/satellite-testing.html IUCC installed Mentat XH45 boxes in Israel and its co- location site in Chicago and found instances of a 160- fold performance increase for TCP streams. (NASA also tested the Mentat boxes; they help with both high- latency and low-latency (70 ms) links, which is applicable to the USs high-performance networks. www.mentat.com/skyx/xh45.html Previously IUCC worked with researchers to TCP tune their systems, but this is not scalable: www.psc.edu/networking/perf_tune.html

30 University of Illinois at Chicago Euro-Link Statement of Work Engineering Advancements NORDUnet has set up native multicast connectivity with most of the STAR TAP-connected networks

31 University of Illinois at Chicago Euro-Link Statement of Work Engineering Advancements RENATER2 is increasing available transatlantic bandwidth. A call for tender is in progress. The transatlantic capacity should be increased above 622 Mbps, including an OC-3 path to STAR TAP. Experiments with QoS services, aiming at a more efficient (in terms of performance and of bandwidth allocation and usage) use of the costly transatlantic infrastructure, and make them operational as soon as possible. Experiment with IPv6 as part of the 6Bone activity. Experiment with end-to-end (campus to campus) QoS services

32 University of Illinois at Chicago Euro-Link Statement of Work Engineering Advancements EVL is collaborating with SARA in The Netherlands on network performance tests SURFnet is cooperatively planning with CA*net3/4 to bring 2.5Gb to STAR TAP as part of the I-WIRE/ Star Light effort

39 University of Illinois at Chicago Scientific Applications CERN Networked experiments of the European Laboratory for Particle Physics (CERN) CERN provides experimental facilities for particle physics experiments, mainly in the domain of high-energy physics. Four very large experiments in man- made caverns intersect the LEP tunnel, constituting about half of CERNs total experimental program for the 1990s. 50 participating institutions, several hundred physicists, in five continents. CERNs Large Electron Positron (LEP) collider, in a 27km tunnel – the largest machine of this type in the world http://www.cern.ch

40 University of Illinois at Chicago Scientific Applications CERN The Globally Interconnected Object Databases (GIOD) Project The Compact Muon Solenoid (CMS) detector will cleanly detect the diverse signatures of new physics at the Large Hadron Collider (LHC), due to be operational in 2005. It will identify and precisely measure muons, electrons and photons over a large energy range. The data is overwhelming. Even though the data from the CERN CMS detector will be reduced by a factor >107, it will amount to over a Petabyte (1015 bytes) of data per year accumulated for scientific analysis. Caltech, CERN, Hewlett Packard, others Particle physicists are engaged in large international projects to address a massive data challenge, with special emphasis on distributed data access. http://pcbunn.cithep.caltech.edu

41 University of Illinois at Chicago Scientific Applications CERN MONARC Project LHC experiments have envisaged Computing Models (CM) involving hundreds of physicists doing analysis at institutions around the world. Regional Centers are intended to facilitate access to the data; with more efficient and cost-effective data delivery to the groups in each world region, using high-speed national networks. This project intends to study network-distributed computing architectures, data access and data management systems that are major components of the CM, and the ways in which the components interact across networks. MONARC (Models of Networked Analysis at Regional Centers) will be created for data analysis from the Large Hadron Collider LHC experiments http://www.cern.ch/MONARC/

42 University of Illinois at Chicago Scientific Applications CERN @ iGrid 2000 Distributed Particle Physics Research California Institute of Technology, USA, USA CERN for authentication and resource discovery, a distributed object database containing several terabytes of simulated events, and a component that enables queries issued by the front-end application to be matched to available computing resources in the system (matchmaking service). http://pcbunn.cacr.caltech.eduhttp://iguana.web.cern.ch/iguana/ http://vrvs.cern.chhttp://cmsdoc.cern.ch/orca This application demonstrates remote viewing and analysis of particle physics events. The application is the front end to an engineered object-oriented global system that incorporates grid middleware

43 University of Illinois at Chicago Scientific Applications Israel Interactive Simulation in the Field of Plant Nutrition This US-Israel Bi-national Agricultural Research and Development (BARD) Foundation project involves hypotheses testing and result evaluation, using an interactive graphic model. SimRoot, a 3D model developed at Penn State, graphically describes the deployment of plant root systems in soil – and predicts the performance of plants under various environmental conditions, depending on their physiological characteristics. Tel Aviv University and Penn State University

44 University of Illinois at Chicago Scientific Applications Israel Visualization of Acetylcholinesterase: Nature's Vacuum Cleaner Acetylcholinesterase (AcChoEase) is an enzyme that plays a key role in the human nervous system. In vertebrates, nerve impulses travel from cell to cell by means of chemical messenger. When an electrical impulse reaches the end of one cell, messenger molecules – acetylcholine (AcCho), in this case – are released to diffuse though the fluid-filled, intercellular, synaptic gap. Upon reaching the destination cell, the AcCho molecules dock into special receptors triggering a new electrical impulse. Much like a vacuum cleaner, the enzyme AcChoEase is constantly sweeping up and hydrolyzing AcCho during this process, so that the whole cycle can begin again. Chemicals that inhibit the action of AcChoEase are being used in the treatment of glaucoma, myasthenia gravis and, experimentally, Alzheimer's disease. In spite of the ability to exploit the enzyme, its precise mechanism of operation is still a mystery. Cornell University, USA; Weizmann Institute of Science, Israel
