Jari Miettinen
21st NORDUnet Networking Conference
Reykjavik, August 24th 2003
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
Outline of the presentation
• Nordic IPv6 deployment status
• the IPv6 network
• special networking activities
• future directions and guidelines
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
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
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
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
Special activities - Forskningsnettet
• University of Copenhagen leading the activity
• multiple different Unix platforms running test services
• dedicated national ethernet-based test network
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
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
Special activities - RHnet
• IPv6 support enabled in the backbone
• ftp.rhnet.is Open Source archive available also with IPv6
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
Futureware
• IPv6 services development with customers
• finalize the basic carrier service
• mature the router OS code
• get more operational experience
Q/A
• something missing/wrong/needs fixing in the deployment?
