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?
