  2. Next Generation Networks for Experiments: Goals and Needs • Providing rapid access to event samples and subsets from massive data stores • From ~500 Terabytes in 2001, ~Petabytes by 2002, ~100 Petabytes by 2007, to ~1 Exabyte by ~2012. • Providing analyzed results with rapid turnaround, bycoordinating and managing the LIMITED computing, data handling and NETWORK resources effectively • Enabling rapid access to the data and the collaboration • Across an ensemble of networks of varying capability • Advanced integrated applications, such as Data Grids, rely on seamless operation of our LANs and WANs • With reliable, quantifiable (monitored), high performance • For “Grid-enabled” event processing and data analysis,and collaboration

  3. Key Network Issues & Challenges Net Infrastructure Requirements for High Throughput • Packet Loss must be ~Zero (at and below 10-6) • I.e. No “Commodity” networks • Need to track down uncongested packet loss • No Local infrastructure bottlenecks • Multiple Gigabit Ethernet “clear paths” between selected host pairs are needed now • To 10 Gbps Ethernet paths by 2003 or 2004 • TCP/IP stack configuration and tuning Absolutely Required • Large Windows; Possibly Multiple Streams • New Concepts of Fair Use Must then be Developed • Careful Router, Server, Client, Interface configuration • Sufficient CPU, I/O and NIC throughput sufficient • End-to-end monitoring and tracking of performance • Close collaboration with local and “regional” network staffs TCP Does Not Scale to the 1-10 Gbps Range

  4. The Rapid Pace of Network Technology Advances Continues Within the Next One to Two Years • 10 Gbps Ethernet on Switches and Servers; LAN/WAN integration at 10 Gbps • Intel 10 GbE server NICs in Beta Test • 40 Gbps Wavelengths Being Shown • NextGen Routers: 100 Mpps forwarding engines, 4 and More 10 Gbps ports per Slot; Terabit/sec backplanes etc. • Broadband Wireless [Multiple 3G/4G alternatives]: the drive to defeat the last mile problem • 802.11 ab, UWB; Mobile: CDMA2000/1xEV-DO

Workshops on HENP Grids and Networks • Feb. 2002: Grid and Network Session Brazil (Rio) • April 2002: Potential of Grids and IT Romania (Bucharest) • May 2002: Internet2 Members’ Plenary USA (Wash. DC) • June 2002: INET2002 (ISOC) USA (Wash. DC) • June 2002: TERENA Annual Meeting Limerick • Sept. 2002: iGrid2002 • Oct. 2002: ICFA Seminar CERN (Geneva) • Nov. 2002: Pan-European Ministerial Romania (Bucharest) Pre-Conference for the WSIS • Nov. 2002: SC2002 • March 2003: CHEP2003 USA (San Diego) • Lepton-Photon 2003 FNAL (Batavia) • 2003: GGF – TBD • 2003: World Summit on the Geneva Information Society (WSIS)

  11. WSIS-RO: Bucharest Nov. 7-9WSIS is 12/03 & 05 (Geneva & Tunis) • The Regional Ministerial Conference, based on the UN/ECE membership, is in preparation of the World Summit on the Information Society - Bucharest, 7-9 November 2002 • The UN General Assembly adopted in 2001 a resolution endorsing the organization of the World Summit on the Information Society (WSIS), to be convened under the patronage of the United Nations Secretary-General, Kofi Annan, with the International Telecommunication Union taking the lead role in its preparation along with interested UN organizations and the host countries. The Summit will offer a unique opportunity for the world community to discuss and give shape to the Information Society by bringing together governments, international organizations, private sector and civil society. In preparation for this Summit regional conferences are organized to develop specific proposals.

  12. WSIS-RO: Bucharest Nov. 7-9WSIS is 12/03 & 05 (Geneva & Tunis) • The Pan-European Ministerial Conference in Bucharest will focus on concrete issues of relevance for the region, but will keep the balance between regional specificity and the global dimension. • The Conference in Bucharest aims at strengthening the relations of cooperation between the participating states with a view to adopting a common action plan in the field of communications and information technology. • It will be an opportunity for presenting national strategies, achievements and challenges that will help the participants to have an accurate view of the stage in the transition process to an Information Society as well as an opportunity to develop a platform for dialogue that includes all major stakeholders at European level – Governments, civil society, private sector and international agencies.

  13. WSIS-RO: Role of New Technologies in Developing the Information Society • Tony Hey, UK Core E-Science Program • Peter Zangli, European Commission • Hans Hoffmann, CERN Scientific and TT Director • Fabrizio Gagliardi: EDG Project Leader • William Johnston, Lawrence Berkeley Lab • Dave Reese or Tom West, CENIC, Pacific and Nat’l Light Rail • Don Riley or Ed Fontegrossi, IEEAF • Harvey Newman, Caltech

  15. Tyco Northern Europe Donation

  16. Tyco Telecomm Donation Summary • Colocation space in NYC for Expanded NY Int’l Exch. Pt • Production R&E Bandwidth: 622 Mbps • NY-London-Groningen (Netherlands) • Connects to IEEAF fiber to Amsterdam & Hamburg • CA-Tokyo-Singapore • Research 10 Gbps optical wavelength • NY-London-Groningen (Netherlands) • CA-Tokyo-Singapore • 200sq.ft. Co-location space in each of global facilities • Additional donations as global build-out continues

  17. CENIC-GEO MOU led to IEEAF • GEO will donate real estate • 15K sq.ft. in each of two new International carrier hotels (Hayward/CA, MD/DC) • 200 sq.ft. in each of other facilities • GEO will try to get others (wet fiber/dry fiber/equipment/etc.) to donate as part of business negotiations

  18. Internet2 HENP WG [*] • Mission: To help ensure that the required • National and international network infrastructures(end-to-end) • Standardized tools and facilities for high performance and end-to-end monitoring and tracking, and • Collaborative systems • are developed and deployed in a timely manner, and used effectively to meet the needs of the US LHC and other major HENP Programs, as well as the at-large scientific community. • To carry out these developments in a way that is broadly applicable across many fields • Formed an Internet2 WG as a suitable framework: Oct. 26 2001 • [*] Co-Chairs: S. McKee (Michigan), H. Newman (Caltech); Sec’y J. Williams (Indiana) • Website: http://www.internet2.edu/henp; also see the Internet2End-to-end Initiative: http://www.internet2.edu/e2e
