  1. Highlights from the recent Esnet International Meeting in Paris Manuel DelfinoApril 9, 1999

  2. Topics that were touched but which I will not cover to avoid repetition or because of scope • Status of TEN-155 • Developments in Multicasting • Medical, weather, fusion, etc. applications • ICFA SCIC • On the topic of Asia: All I mention is concerns about Europe-Asia interconnect

  3. ESnet International Meeting James Leighton Department Head Networking & Telecommunications Dept. Computing Sciences Directorate Lawrence Berkeley National Laboratory Paris, 17 Feb, 1999

  4. CURRENT STATUSStatistics • Dec, 1998 • 32.4 Giga-packets accepted • 12.9 Tera-bytes accepted • 398 bytes/packet (average packet size) • Dec, 1997 • 15.6 Giga-packets accepted • 6.98 Tera-bytes accepted • 447 bytes/packet (average packet-size) 6Jan99

  5. OTHER TOPICSProcurement Activities • Sprint Contract Extension • Have signed a two-year contract extension with Sprint • Will extend current contract to Aug. ‘01 • Contract includes ATM port charge reductions for FY99 and additional reductions for FY00 and FY01 • Follow-on Procurement underway (ESnet3) • Will overlap Sprint contract, roughly from FY00-04 • Will ask for both production and advance capabilities • one goal is SSI/P support up to 1Tbps by ‘03 • Completed 1st vendor briefings during Jan ‘99 • Plan to launch formal RFP April ‘99 • Plan for contract signature by fall ‘99

  6. CURRENT ISSUESUniversity Access • Shifting from reliance on vBNS • vBNS contract with NSF expires Mar ‘00 • no intent to renew/rebid (?) • but something else may be going on … • Focus now on peerings with Abilene & GigaPoPs • First GPoP up with (CalREN2-North) @ OC12 • Will do interim peering with Abilene • Peering with CalREN2-South underway @ T3 • First peering with Abilene up via Chicago Pop @ OC3 • Planning on peering with Atlanta GPoP at T3 • Will peer with Abilene across ATM GPoP 6Feb99

  8. RESEARCH & ADV. TECH.Current Activities (1/3) • Differentiated Services • testing & evaluating backbone technologies • e.g. traffic shaping, queue management, policing, classifiers, marking, etc. • looking at overall initial architecture for ESnet DS approach • considering a low-end (Petite) and high-end (Gonzo) approach • try to minimize startup complexity and cost • deploying clipper testbed facilities • Now have routers interconnected at ANL, LBNL, SLAC • developing white paper on QoS ancillary issues - “what makes QoS so complex to deploy” • Participating member in I2/Qbone projects

  9. NEW INITIATIVESNGI • The Next Generation Internet (NGI) is a multi-year, multi-agency federal research and development program to develop, test, and demonstrate advanced networking technologies and applications. • DOE has $15M for FY99 • Several Calls for Proposal have been issued • Basic Technologies, Applications, Testbeds • ESnet is participating in several proposal submissions

  10. NEW INITIATIVESIT2/SSI • One of the Clinton Administration's major science and technology initiatives in the FY 2000 budget request to be sent to Congress will be a $366 million, or 28%, increase, in information technology research. The program is called "Information Technology for the Twenty-First Century," or IT2. • DOE’s program is known as the SSI/SSP (Science Simulation I/P) • Proposed Agency Budget Increases: • National Science Foundation - $146 million • Department of Defense - $100 million • Department of Energy - $70 million • NASA - $38 million • NIH - $ 6 million • NOAA - $6 million • DOE’s program contains a networking component • DOE’s program calls for Tbps networking capability by ‘03 • ESnet has launched an RFP to meet such requirements

  30. Technical Innovation: Quality of Service • Chair: Ben Teitelbaum, Internet2 staff • Focus: Multi-network IP-based QoS • Relevant to advanced applications • Interoperability: carriers and kit • Architecture • QBone distributed testbed

  31. Big Problem #1: Understanding Application Requirements • Range of poorly-understood needs • Both intolerant and tolerant apps important • Many apps need absolute, per-flow QoS assurances • Adaptive apps may require a minimum level of QoS, but can exploit additional network resources if available

  32. Big Problem #2: Scalability • # flows through core >> # flows through edge • Goal: keep per-flow state out of the core • Design principles • Put “smarts” in edge routers • Allow core routers to be fast and dumb

  33. CampusNetworks CampusNetworks GigaPoPs GigaPoPs Big Problem #3: Interoperability ... between separately administered and designed clouds ... Backbone Networks(vBNS, Abilene, …) … and between multiple implementations of network elements ... … is crucial if we are to provide end-to-end QoS.

  34. Premium Service • Emulates a leased line • Contract: peak rate profile • PHB = “forward me first” (e.g. priority queuing, WFQ) • Policing rule = drop out-of-profile packets • On egress, clouds need to shape Premium aggregates to mask induced burstiness • GigaPoPs: • scalable access to wide-area resources • Backbones: • vBNS • Abilene

  36. Internet2 International Collaborations • Building peer to peer relationships • Looking for similar goals/objectives and similar constituencies • Mechanism: Memoranda of Understanding • Signed: CANARIE, Stichting SURF, NORDUnet, TERENA*, SingAREN, JAIRC, UKERNA-INFN/GARR-DFN-Verein-RENATER

  37. International collaborations cont’d • Network interconnection • Interconnection at STAR TAP (CAnetII, SURFnet, NORDUnet, SingAREN underway) • Second interconnection directly with Abilene (NY - NORDUnet, SURFnet) • Specific project collaboration • QBone (e.g. SURFnet an initial participant) • middleware • research/learning applications

  38. Next Steps • Continue to interconnect member desktops and servers at high speed • Continue to support advanced applications development • focus on multi-campus implementations • Adopt, develop and implement • QoS end-to-end • middleware end-to-end • new business models

WHITE HOUSE Executive Office of the President Office of Science and Technology Policy Presidential Advisory Committee on High Performance Computing and Communications, Information Technology, and the Next Generation Internet National Science and Technology Council Executive Committee Committee on Technology Subcommittee on Computing, Information, and Communications R&D National Coordination Office (NCO) for Computing, Information, and Communications Human Centered Systems Working Group (HuCS) Education, Training, and Human Resources Working Group (ETHR) Federal Information Services Applications Council (FISAC) High Confidence Systems Working Group (HCS) High End Computing and Computation Working Group (HECC) Large Scale Networking Working Group (LSN) Next Generation Internet Implementation Team

  41. What is NGI? • “The goal of the NGI is to conduct R&D in advanced networking technologies, to demonstrate those technologies in testbeds that are 100 to 1,000 times faster than today’s Internet [~ 1 megabit/sec], and to develop and demonstrate on those testbeds revolutionary applications that meet important national needs and that cannot be achieved with today’s Internet.” • In essence “to let our researchers live in the future.”

  47. Presentations from European participants in Esnet mtg • All European participants presented status of their national networks and their international connectivity • I have picked two presentations (Italy and Germany) to illustrate some points. • Common themes are Gigabit testbeds and plans, QoS/Differentiated services • Idea of “justified use” vs. “general Internet”
