  1. The State of the Research Networking World Thom Stone May 2002

  2. Topics • Technology and HPRENs • Areas • North America • Europe • Asia • South America • Africa

  3. Technology Updates • Wide area Ethernet • Resilient Packet Ring • Gig-E and 10 Gig Ethernet connections over wavelengths (SURFNET had a little Lambda) • New NREN • “Distributed StarTAP” • StarLIGHT • The “great technology dying” • Western Europe and Asia/Pacific march ahead, South America takes some steps, Africa lags

  4. Beating the Standards • Europe rolling out 10 Gig Ethernet over the wide area, Canada switches Lambda and US follows • ATM and SONET are becoming passé • Resilient Packet Ring Standard (RPR-802.17) brings protection, fast convergence • RPR is IP centric • Pure Lambda switching is next

  5. New NREN Backbone Up and Working • OC-12 ATM core with some OC-3 tail circuits • Connected to StarLIGHT (optical) in Chicago for international peering • NREN and NPN share bandwidth - NREN for Network Research, NPN for application prototyping. Three-tier HPREN model (NISN, NPN, NREN)

  6. Office of the Future Grand Challenge Applications Earth Sciences Spacecraft Future sites (dashed lines) NREN Sites OC-12ATM Hybrid Ground Station (35 Mbps) NREN Network Architecture GRC NGIX-Chi NGIX-East ARC/NGIX-West GSFC NASA WAN Testbed HQ JPL MSFC

  7. Distributed StarTAP • Allow for Non-US networks to terminate at coastal locations and use “International Transit Service” (ITN) to proxy peer via Abilene to STARTAP • Thai network (UNINET) lands at L.A.,South American networks (AMPATH) land in Miami • Abilene does not allow for FEDNET peering to ITN sites

  8. International HPRENs

  9. StarLIGHT • New optical peering point in Chicago • Experimental optical switching • Very high speed connections—Gig-E or higher • Will carry transit from StarTAP

  10. The Technology/Telecom Slump • Global Crossing gone and other IRCs in danger. Do not know how this will affect AMPATH or other transoceanic connections • Fiber switching, advanced routing, Wide/Metro area Ethernet companies all go into bankruptcy. Many established companies in trouble or pulling back

  11. CAnet*4 the Optical Avatar • Canarie is the leader in all optical networks and switching • DWDM backbone • New protocols such as Optical Border Gateway Protocol • Provide transit for other networks

  12. Europe Does Gig • TERENA - GEANT supercedes 10-155. 10 Gig-E Lambda backbone for Europe • Dutch SURFNET lights the Atlantic • 10 Gig-E IP over Lambda terrestrial backbone • Connection to StarTAP at 622 Mb/sec (OC-12) • Dual connection to StarLIGHT at GIG-E speed • Teleglobe and Global Crossing

  13. SuperJanet - Rule Britannica • Last month bought up two 2.5 Gig (OC-48 POS) links to US. Abilene, ESNET share one. • Also OC-48 POS to GEANT

  14. Eastern Europe Attempts HPRENS • CEENET Central and Eastern European Networking Association • 26 Country networks • Low-speed connections to the outside • Russia - FASTnet connected to StarTAP at OC-3 (Jan. 2002)

  15. Asia Pacific • AARNET • Current ATM backbone, going to 10 G-E in the near future • Dual 155 Mb/sec (OC-3) SONET links to the US • APAN • Dual OC-12 circuits to Chicago. One POS one ATM • Singapore (SINGAREN) • ATM National backbone 27 Mb/sec ATM to ABILENE/StarTAP • Malaysia (TEMAN) • ATM backbone -Satellite Link to US networks • Thailand (UNINET) • ATM backbone- 17 Mb/sec connection to Abilene ITN at L.A.

  16. More Asia Pacific • Philippine Research, Education, Government Information Network (PREGINET) • ATM network In planning- Connects now via APAN • CERNET- China Research and Education Network- OC-48 POS backbone connects to other China Academic networks • Networks for HK, Taiwan, Korea, etc.

  17. AMPATH - HPRENS for South America • Florida International University, Global Crossing, Cisco team to bring High Speed connectivity to networks in South America • DS-3 ATM links, routers in a ring around South America • Eleven connections now up • What will the demise of Global Crossing do?

  18. Africa Bleak Outlook • UNEP satellite based network decommissioned this year • National Library of Medicine network being redesigned • Uninet, the South African network has no external connectivity • The UN is going to hold sessions concerning the lack of Internet resources in Africa

  19. Conclusion • High-speed connections are here. Applications and protocols may not be ready for them. TCP performance is limited on single flows. • The current economic downturn could have a negative impact in the next period. New technologies may not emerge as fast as they have in the past. • The problem of the “have not” areas must be addressed.
