  1. Can Internet transport technology support Grid Applications ? • National Institute of Communications Technology • Internet Architecture Research Group • Katsushi Kobayashi

  2. Agenda • Requirement for transport • Internet Transport researches in NICT • R&D network activities in Japan

  3. Who I am. • On SC’98 (Orlando), transpacific SDTV quality video transport (25Mbps) was demonstrated as an iGrid exhibition. • Contribute video system for tele- Ultra-High Voltage Electron Microscopy between US (UCSD) and Japan(Osaka-U). http://www.sfc.wide.ad.jp/DVTS/sc98.html

  4. Requirement for transport- on Grid applications - • Requirements for Internet transport are diversified, since different kind of application have different requirement. • A lot of application ideas are emerged with increasing network power, i.e. bandwidth, deployment and stability. • Transport protocol well deployed is not enough for leading-edge applications, e.g. Grid’s, on high-end network.

  5. Requirement for transport(cont’d) • Different communication types are required different applications: • massive bandwidth communications (e.g. Data Grid) • reliable and lower delay communications (e.g. derivatives from parallel computing middleware ) • one to many realtime communications (e.g. Access Grid) • reliable one to many communications

  6. Requirement for transport(cont’d) Real-time Access Grid Expanding Leading Edge of Network with Innovation VoIP for Parallel Processing Transaction Data Grid Terminal Data Transfer Reliability

  7. Requirement for transport(cont’d)- long-fat pipe issue- • fat-pipe issue will be led by Growing link bandwidth • 1 2/3 hour is needed to reach max window size for single TCP, in the case of 10Gbps, 100 msec RTT and 1.5KB mss, also unrealistic loss rate (1/5,000,000,000) • Some application still require single TCP stream, e.g. network storage. • Difficult to obtain enough performance with current transport stack, e.g. bandwidth difference 10Kbps to 10Gbps, and packet loss and delay difference from wireless to fiber.

  8. Requirement for transport(cont’d) • Some approaches are being studied to accomplish massive bandwidth communications: • Circuit switch (Lambda, GMPLS..) • Minimize transport layer’s overhead using provisioned network infrastructure. • Packet switch (IP) • Improve transport performance with protocol development and/or implementations.

  9. Requirement for transport(cont’d) • Light transport protocol assuming provisioned network using Lambda and/or GMPLS • SABUL/UDT, Tsunami • Improve transport performance on current Internet Infrastructure. • FastTCP, HSTCP, Scalable TCP.. • Modify Internet architecture to support massive transport layer. • XCP, TCP-QS, PPTP.......... ← Our Approach

  10. Requirement for transport(cont’d) • Although researcher emphasize the advantages of their own approach, each approach could be able to be combined. • Transport technology researches on both best-effort packet basis and/or provisioned network have been still ongoing and have not reached consensus yet, to keep this diversity of approaches in this layer is essential.

  12. Outline of the New Research and Development Testbed Network (JGN Ⅱ) 1. Objectives The following measures are being promoted through collaborations with industries, academia, government ,and regional organizations:  ・To promote basic/fundamental research and development (R&D), applied R&Dand demonstration on wide-ranging information and communications technologies  ・To stimulate regional R&D activities  ・To develop human resources through practical research activities  ・To explore the prospects of the future IT society 2. Features  ・Open network testbed for R&D  ・Nationwide network and access points in all prefectures (63 in total)  ・Maximum 20Gbps backbone network  ・Three kinds of services (L1:dark fiber, L2: ethernet, L3:IP)  ・Japan-U.S. circuits as a part of the network ( launched in August 2004) 3.
