NGI-NZ Society

• Research, Innovation & Education
• At High Speed

An Innovative New Zealand

• "Collaborating at Speed"
• Access to Next Generation Internet "crucial"
• Many other countries have such a network
• Research and Education, and "innovation economy"
• NGI-NZ Society the spearhead

Around the World

• AARNet and Grangenet in Australia
• Internet2 in USA, CANARIE in Canada
• Research and Education sectors on private networks: AUPs and member conditions
• Very high speed networks. Different business models in Telcos

Thinking About Data

• Voice is 64 Kbps, real time - only local access is "bursty"
• Data can be real time or store and forward. Very bursty and variable bandwidth
• Early technologies mix data and voice; not cost-effective
• Voice, text, image, video, file transfer - all data
• Computers and databases become universal tools - data communications ought to be about remotely connecting them

LAN interconnectivity

• Interconnecting LANs:
  • A telecommunications link for digital tools:
    • LANS - PCs, servers, host computers etc
    • TV and Film studios
    • Comms tools - phones, PABX
  • All demand different network characteristics
• Internet is universal access
• Technology has led to abundant capacity at low incremental cost
• The telecommunications industry is constraining take-up: scaling up is too expensive

The data tariff structure

• Data tariffs are based on leased lines: dedicated pipes charged for every second of every hour of every day
• Telcos aggregate voice calls onto high bandwidth
• Data is harder to aggregate, so LANs provide high bandwidth loops to all users on a burst-over-shared-access basis
  • Same pipe as LAN itself
  • Always-on access
  • Pay per burst long distance
• Telcos don’t do this anywhere in the world: Only R+E networks do

Using a LAN speed network: Grid services

• Computer grid - sharing spare computer capacity
• Data grid - sharing databases
• Access grid & distributed visualisation
• Instrument grid - telepresence

Justification needed?

• Eg: Grid Computing - think computational needs, not computers:
  • Computer grids - better utilisation
  • Data grids - better user efficiency
  • Scalability and flexibility improvement
  • Research collaboration - accessible data+s/w
  • Q-S enabled network for Voice and Video over IP
  • Multicast enabled backbone

A programme for NZ

• A different service-tariff model
  • LAN based
  • Big pipes
• A national network first with international connectivity
• Expanding local access
• Conditions of use and membership considerations

Network Architecture

• National
  • A private network and a not-for-profit organisation
  • The NGI core can provide multiple GigE service
  • Usage conditions:
    • Any type of traffic between members
    • Sub-contractors and suppliers case studies
    • Gateway to international R+E networks
    • "Preferred" only supplier of access
• International
  • RFO for International connectivity
  • Several deal possibilities
  • Partnering
  • Primary supplier/market
  • Secondary market
  • Phased intro to national and international service
  • Funding, costs and economic development driven

Quick start-up possible

• Existing arrangements can be used
• Up and running within 8 weeks
• Start-up national network and international access to R+E - Abilene, AARNet

Conclusion

• NGI-NZ is about establishing an advanced network for R+E+I
• NZ trails the rest of the world, but can leapfrog
• Technology advances allow new model
• High speed networks important for social development and economic growth
