Slide1:  TransPAC High-performance connectivity between the US and the Asia-Pacific region and Related Projects Donald F. (Rick) McMullen TransPAC U.S. User Services Indiana University PRAGMA Workshop I - March 11, 2002 The TransPAC Project is funded by the US National Science Foundation and the Japan Science and Technology Corporation Topics to be discussed:  Topics to be discussed TransPAC background and technical overview Global Network Operations Center iVDGL Grid Operations Center Global Terabit Research Network Slide3:  The TransPAC Project provides high-performance network connectivity between the Asia-Pacific region and the United States for the purpose of encouraging educational and scientific collaboration among scientists and researchers in these respective areas. Specifically, TransPAC connects the Asia-Pacific Advanced Network (APAN) to the US high-performance infrastructure (Abilene, the vBNS and “Fednets”) and to other international high-performance networks (Canarie, and EU networks). Background Slide4:  The TransPAC Project is jointly funded by the US National Science Foundation and the Japan Science and Technology Corporation. Initial 35Mbps ATM link from Tokyo to STAR TAP brought up September 1998. Several upgrades, latest in October 2001; currently two OC-12 routes (1.244Gbps aggregate) Indiana University provides technical and administrative support for TransPAC in the US. KDDI provides similar support for TransPAC in Japan. Background 2 Slide5:  On 15 October 2001, TransPAC was upgraded to 1.244Gbps. The new TransPAC network has dual 622Mbps connections from Tokyo to Seattle (Pacific Wave Connection Point) [POS] and to Chicago (StarLight Connection Point) [ATM]. The Tokyo-Seattle link is supplied by Teleglobe. The Tokyo-Chicago is supplied by KDDI. TransPAC Upgrades in 2001 Slide7:  TransPAC after October 2001 Slide8:  New OC-12 POS circuit from Tokyo to Seattle Trans-Pacific and west-coast circuit provided by Teleglobe Terminates into a Juniper M10 at the Pacific Northwest Gigapop Weekly Traffic graph from – 1/7/02 1/14/02 Slide9:  New OC-12 ATM circuit from Tokyo to Chicago Trans-Pacific link provided by KDDI Contains multiple PVCs to provide direct peering with US HPRENs Weekly Traffic graph from – 1/7/02 1/14/02 GlobalNOC:  GlobalNOC Manages international network connections from advanced research and education networks in the Asia/Pacific, Europe, Russia and South America One-stop NOC support for NSF HPIIS funded projects TransPAC EuroLink AmPath MirNet STAR TAP 24x7x365 network management and problem resolution This NOC also manages the Abilene network Marginal costs to add new networks is small and known. Slide12: iVDGL Grid Operations Center at IU:  iVDGL Grid Operations Center at IU The International Virtual Data Grid Laboratory supports these data intensive projects: Laser Interferometer Gravitational-wave Observatories (LIGO) ATLAS and CMS experiments at CERN Sloan Digital Sky Survey (SDSS) National Virtual Observatory (NVO) In conjunction with the GriPhyN project, the iVDGL Grid Operations Center (iGOC) provides technical support and grid management infrastructure (equipment and people) to the iVDGL consortium Single point of contact for security and directory services, resource monitoring and problem tracking/resolution Atlas tier 2 site support at Indiana University Network-enabled science and research in the 21st century:  Network-enabled science and research in the 21st century Science and research are becoming progressively more global with network-enabled world wide collaborative communities rapidly forming in a broad range of areas Many are based around a few expensive – sometimes unique – instruments or distributed complexes of sensors that produce vast amounts of data These global communities will carry out research based on this data This data will be analyzed by supercomputers and large computer clusters, visualized with advanced 3-D display technology, and stored in massive or large data storage systems – all of this will be distributed globally Note the tight interaction between computation, storage and networking Some examples of global science:  Some examples of global science NSF-funded Grid Physics Network’s (GriPhyN) need for petascale virtual data grids (i.e., capable of analyzing petabyte datasets) ( International Virtual Observatory (NVO  IVO, The Large Hadron Collider (LHC) located at CERN ( Earthscope Geological and Seismic Collaboratory ( Sloan Digital Sky Survey (SDSS) ( Earthscope Geological and Seismic Collaboratory:  Earthscope Geological and Seismic Collaboratory Earthscope applies the latest observational, analytic and telecommunications technologies to investigate the structure and evolution of the North American continent and the physical processes controlling earthquakes and volcanic eruptions Four components of a network-based instrument collaboratory USArray - continental scale seismic array to provide a coherent 3-D image of the lithosphere and deeper Earth SAFOD - San Andreas Fault Observatory at Depth PBO - Plate Boundary Observatory InSAR synthetic aperture radar images of tectonically active regions Earthscope - International Connections:  Earthscope - International Connections “The U.S. scientific community is poised to implement the Earthscope initiative that would provide urgently needed observations on a global scale.”1 Some project funding from the International Continental Scientific Drilling Program (ICDP); members include Canada, China, Germany, Japan, Mexico, Poland, and the US Array extensions in Canada and Mexico Large ground motion sensor array in Japan Taiwan ground motion sensor array 1Testimony before Congress, 3/21/2001 by M.

Slide21:  Our challenge is to design, build and manage the reliable, stable networks needed for scientists to collect and analyze their data globally. Global Terabit Research Network GTRN:  Global Terabit Research Network GTRN Global Cyber Infrastructure Network Requirements:  Global Cyber Infrastructure Network Requirements Provide a single global backbone inter-connecting global network access points (GNAPs) that provide peering within a country or region Provide global backbone speeds comparable to those at NRRENS, i.e. OC192 in 2002 Allow coordinated global advanced service deployment (e.g. QoS, IPv6, multicast) Persistent: Based on stable carrier infrastructure, leased/owned fiber, or wavelengths. Based on long-term (5-10 year) agreements with carriers, router vendors and optical transmission equipment vendors Scalable – e.g. OC768 by 2004, multiple wavelengths running striped OC768 by 2005, terabit/sec transmission by 2006 Allow GNAPs to connect at OC48 and above. To scale up as backbone speeds scale up Provides a production service with 24x7x365 management through a global NOC structure The Global Terabit Research Network:  The Global Terabit Research Network Announced 18 February 2002 as a production service A partnership to establish a true world-wide next generation Internet to interconnect national and multinational high speed research and education networks as a critical part of global cyberinfrastructure A coherent global solution that expands global cyber infrastructure for e-science Involves NREN-Consortium: Dante, Internet2, Indiana University, CANARIE, StarTAP/Starlight & Pacific Wave Regionally based (initially Europe & North America; soon Asia Pacific,… ) Currently connects the major research and education networks in Europe and North America Slide25: Future GTRN Expansion :  Future GTRN Expansion Anticipated additions in the next 90 days GTRN AS at STAR TAP/Starlight GTRN AS at Pacific Northwest GigaPop (PNG) Tunneled capacity across Abilene to connect these points Resulting GTRN topology: Europe, North America; Asia Pacific expected soon Participation in New York layer two exchange point (Manhattan Landing) Further deployment of GNAPs (e.g. in the Asia Pacific) Extension to the Latin Americas via AMPATH Slide27:  Questions and Comments Useful Links: Main TransPAC Web page: TransPAC NOC: TransPAC traffic graphs: GlobalNOC: iGOC: GTRN:
