Title: The State of the Research Networking World


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

6
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)

7
NREN Network Architecture
GRC
NGIX-Chi
NGIX-East
ARC/NGIX-West
GSFC
NASA WAN Testbed
HQ
JPL
MSFC
8
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

9
International HPRENs
10
StarLIGHT
  • New optical peering point in Chicago
  • Experimental optical switching
  • Very high speed connectionsGig-E or higher
  • Will carry transit from StarTAP

11
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

12
CAnet4 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

13
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

14
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

15
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)

16
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.

17
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.

18
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?

19

20
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

21
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.
