Can Internet transport technology support Grid Applications ?

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.
