General trends within nrens Progressive move to more direct use of fibre Provisioning using sdhethernet or Wavelengths Move towards longer term planning horizons 15-20 year fibre leases and self provisioning
6 General trends within NRENs • Progressive move to more direct use of fibre • Provisioning using SDH/Ethernet or Wavelengths • Move towards longer term planning horizons • 15-20 year fibre leases and self provisioning
USA Abilene network(Internet2 backbone) 10Gbps backbone in production 2003 National lambda rail (nlr) Developing a national wdm network for research and experimental use Dark fibre is procured Use ethernet over wdⅣ IPv6 is adopted
