Issues

• Technical
• Speed on a fibre
• Switching (packet, circuit or combined)
• Multiple Lambda or Fibre (dark or lit)
• Political
• Geopolitics
• Financial
• Organisational

4
Technical

• Speed on the fibre
• At present 10 Gb/s/lambda (in the laboratory 80)
  in near future 40 Gb/s/lambda in production
• Total capacity at this time 150 Gb/s
• A single planned experiment (VLBI-E) of the order
  of 15 Gb/s
• GRID computing - massive data, high speed, QoS
• GÉANT will have to upgrade in the near future

Ipv6 Land Speed Record

• Internet2 Land Speed Competition
• October 9, 2002
• ARNES, RedIRIS, DANTE
• Static routing, native IPv6, standard TCP/IP,
  single stream
• Route SI - AT - NY - UK - FR - CH - IT - ES
• Length 14800 km
• 5154 terabit-meters/second 384.22 Mb/s
• Better than any previous single/multiple IPv4 or
  IPv6
• Concurrently with the production traffic

6
Technical

• Switching
• Present IP technology employs packet switching
• Future applications require high speed dedicated
  links
• Planning for a layered, mixed technology network
  with IP and optical switching
• Multiple lambda, dark or lit fibre
• Dark fibre requires man on wheels
• Regardless of the fibre glut they are not
  available in all places
• Stick to multiple lambda for a while

Global Networking some way to go
8
Horses for Courses.

• A single approach to developing global
  connectivity with all regions is not practical
• Different stages of networking development.
• Different levels of regional organisation
• Different funding levels and structures
• Various approaches needed for greatest effect and
  most cost effective

9
Options

• Come to GÉANT
• Euro-centric approach, offers transit within and
  across the EDA, would lose/slow most
  inter-regional connectivity if sole approach
• Co-operative development
• The GTREN approach, fairest but slow, cumbersome
  and potentially complex to administer. Embryonic
  networks not ready for this
• Meet in the US
• The historical approach, gave connection to all
  established networks, but unequal costs, doesnt
  help develop embryonic networks
• Inter-regional consortium backbone
• GTREN owned by consortium of regional networks,
  complex and politically difficult to set up,
  shares costs

10
Come to GÉANT Option

• Most applicable for Central Asia, Asia Pacific
  and Mediterranean, also relevant to Latin
  America and other regional networks
• Gives Connectivity across GÉANT EDA to all
  European NRENs and other regional networks
• NREN or regional entity provide connection to EDA
• Termination on GÉANT router

11
Co-operative Development Option

• Most applicable to North America
• Transatlantic connectivity provided by GÉANT
  7.5Gb/s
• Connectivity provided by North America10 Gb/s
  ????
• Problems by North American funding issues, driven
  by IEEAF donations
• Co-operative approach is complex to manage but
  worth continuing
• Proposed bilateral collaboration with Canarie

12
GÉANT Inter-Regional Backbone Option

• Most applicable to
• Asia Pacific 2003 (proposed in TEIN)
• Latin America 2004 (already planned through ALIS)
• Mediterranean 2005?
• Extends GÉANT backbone into these regions
  building on transatlantic experience
• Invite in-region NRENs to connect at own expense
  to the nearest regional GÉANT PoPs
• As regional networking develops, seek cost
  sharing

13
Financial

• Costs still significant
• Telcos need income - not reducing prices, willing
  to upgrade
• Cost of routers becoming a problem
• Cost of local tails !
• Problem of cost sharing with the US networks a
  serious issue

14
Conclusion

• GTRN - a dream?
• Yes, a dream in short term sense, if speaking of
  networks with trunks running at terabit speeds
• Not a dream if speaking of the global
  connectivity
• Not a dream if speaking of backbone networks with
  aggregate speeds of multiple terabits per second
• Timescale - 3 to 4 years
