Presentation Transcript

  1. Nordic NREN Jari Miettinen 21st NORDUnet Networking Conference Reykjavik, August 24th 2003

  2. The author • M.Sc. from Helsinki University of Technology 1998, started in CSC/Funet later same year • multiple resposibilities during the years, nowadays ”one of those backbone fellows” • special professional interests: DNS, NTP, DDoS and IPv6 • working as NORDUnet 6NET coordinator

  3. Outline of the presentation • Nordic IPv6 deployment status • the IPv6 network • special networking activities • future directions and guidelines

  4. Deployment status (1) • official addresses in use: • SUNET 2001:06B0::/32 • UNINETT 2001:0700::/32 • FUNET 2001:0708::/32 • Forskningsnettet 2001:0878::/32 • NORDUnet 2001:0948::/32 • 6BONE addresses mostly abandoned

  5. Deployment status (2) • customer universities: depending on research interests yes/no • services: experimental, early services available (ftp archives etc.) • access: tunnels most used interface media, conversion to native links underway • backbone: near production-class

  6. Deployment status (3) • active research field among technically oriented university laboratories and NRENs • strong Nordic involvement in the 6NET project (www.6net.org) • Nordic workgroup e-mail list and Web publishing area in www.nordu.net

  7. The IPv6 core network • NORDUnet IPv6 star: common IPv6 core router with native STM-1 level links to each country, dual-stack in the backbone • IPv6 over IPv4 tunnels as backup • tunnels to some 6BONE sites • world-wide connectivity: STM-1 to 6NET, dual-stack to IPv6 GÉANT RSN

  8. Special activities - Forskningsnettet • University of Copenhagen leading the activity • multiple different Unix platforms running test services • dedicated national ethernet-based test network

  9. Special activities - SUNET • operating the NORDUnet IPv6 core • piloting hardware-based L2TPv3 IPv6 tunnels for customer access in backbone giving decicated FE interface • internal IPv6 DNS

  10. Special activities - UNINETT • long-term interest and work in IPv6, separate national testbed in operation since 1998 • special activity in wireless access and multicast research • deployed IPv6 in the backbone (64 routers) • 6to4 gateway, most services available • present with IPv6 on the Norwegian IX

  11. Special activities - RHnet • IPv6 support enabled in the backbone • ftp.rhnet.is Open Source archive available also with IPv6

  12. Special activities - CSC/Funet • core forwarding IPv6 with hardware using Juniper routers • Nordic 6to4 relay service for experimenting • present with IPv6 in the Finnish Internet Exchange (FICIX) • piloting with the first dual-stack customers • newsfeed over IPv6 up&running

  13. Futureware • IPv6 services development with customers • finalize the basic carrier service • mature the router OS code • get more operational experience

  14. Q/A • something missing/wrong/needs fixing in the deployment? • contact the author
